break. So what does this mean to modern oscilloscopes?Wave Inspector®Navigation and Search: Simplifying Waveform AnalysisApplication Note 2As designs become faster and more complex, the need for long records, more bandwidth and higher sampling rate, will also increase. Record length is the number of samples an oscilloscope can digitize and store in a single acquisition. The longer the record length, the longer the time window the oscilloscope can capture with high timing resolution (high sample rate). The record length required for a specific application is directly affected by the bandwidth and sample rate. As bandwidth goes up, the sampling rate mustbe approximately five times higher to accurately capturethe signal’s high frequency content. As the sampling rate goes up, a given time window of signal acquisition requires more samples.For example, to capture 2 milliseconds of a 100 MHz signal at 5 GS/s requires a 10 million point record. (Divide2 milliseconds by the 200 picosecond sample interval.) Even at lower frequencies, there are many applications that require long records. Just capturing a single frame of NTSC video (two fields in a 1/30th of a second interval, at 100 MS/s to resolve all the luminance information) requires over3 million points (33 milliseconds divided by 10 nanoseconds). Capturing several seconds of bus traffic on a 1 Mb/sCAN bus to diagnose problems in an electro-mechanical system may require 10 million points for adequate resolution. These and a variety of other applications have driven and continue to drive the need for longer and more detailed data capture windows.Analyzing all that DataThe first digital oscilloscopes had very short record length. As such, it was easy to see everything the oscilloscope captured because it was all on the screen at one time. As oscilloscopes evolved and records got longer, horizontal scrolling was used to see all the data. This was not a big issue as you move from one screen’s worth of information to two, then up to four, eight, twenty, etc. However, as records became longer and longer with each generationof oscilloscope, the time required to look through all the data captured in a single acquisition grew longer and longer.We are now dealing with record lengths in the millions of points that represent thousands of screens worth of signal activity. By way of comparison, imagine trying to find what you’re looking for on the Internet without the assistance of your favorite search engine, web browser, or bookmarks.It would be like searching for a needle in a haystack. Until recently, this is what oscilloscope users faced with their long record length oscilloscopes. Clearly, the old solutions will no longer work.Wave Inspector ®Navigation and Search: Simplifying Waveform AnalysisApplication Note3/oscilloscopes Wave Inspector ®Navigation and SearchAvailable on the MSO/DPO4000, DPO3000, andMSO/DPO2000 Series oscilloscopes, Wave Inspector ®controls make working with long records and extracting the answers you need from your waveforms a simple and efficient process.Zoom / PanMost digital oscilloscopes on the market today offer some form of zoom capability. However, the controls associated with the zoom view (zoom factor and position) are oftenburied in menus or multiplexed with other front-panelcontrols. For example, the zoom window’s horizontal position is typically controlled by the horizontal position knob on the front-panel. Once you’ve zoomed in on an event of interest, if you want to move the zoom window to another location in the acquisition it typically means either turning the horizontal position knob countless times to slowly move the window to the new location, or zooming back out, adjusting the window’s location and then zooming back in. Neither approach is efficient or intuitive. It becomes even less efficient when you have to navigate through menus just to access these basic zoom controls.Figure 1.Wave Inspector ®provides dedicated front-panel controls for efficient waveform analysis.Wave Inspector ®ControlsWave Inspector®Navigation and Search: Simplifying Waveform AnalysisApplication NoteAs shown in Figure 1A, Wave Inspector provides a dedicatedtwo-tier front-panel Zoom / Pan knob for efficient waveformnavigation. The inner knob controls the zoom factor. Thefarther clockwise you turn it, the farther you zoom in. Turningit counter-clockwise zooms back out and ultimately turnszoom off.The outer ring is a force/rate sensitive pan control. Turningit clockwise pans the zoom window right on the waveform,counterclockwise pans it left. The farther you turn it, thefaster the zoom window moves across the waveform. InFigure 2, we can quickly navigate from one packet to thenext by simply turning the pan control in the desired direction.Even with a 10 million point aquisition, you can rapidly movethe zoom window from one end of the record to the otherin a few seconds, without ever having to change yourzoom factor.In Figure 2 we’re probing an I2C bus. The complete acquisitionis shown in the upper window and the zoomed portionis in the lower, larger window. In this case we’ve zoomedin to view the decoded address and data values for oneparticular packet.Figure 1A.Wave Inspector®provides dedicated front-panel zoomand pan controls.4Wave Inspector ®Navigation and Search: Simplifying Waveform AnalysisApplication Note5/oscilloscopes Figure 2.Navigating through a long acquisition of an I 2C bus.Wave Inspector®Navigation and Search: Simplifying Waveform AnalysisApplication NotePlay / PauseMany times when debugging a problem, you don’t know what’s causing the problem so you’re not sure what to look for in the waveform you’ve acquired. However, you know you’ve captured the time window that contained the problem and you now need to look through the data you’ve captured to see if you can find the issue. Again, on most modern oscilloscopes this is done by manually turning the horizontal position knob countless times to inspect the acquired waveforms for any suspicious activity. Wave Inspector®controls help in this area as well. You can simply press the Play button on the front-panel to have your zoom window automatically pan across the waveform. Play speed and direction are adjusted using the intuitive pan control. The farther you turn the pan control the faster the waveform plays by. This allows hands-free playback so you can concentrate on what’s important – the waveform itself. In the I2C example (Figure 2), you could play the waveform while watching the decoded address and data values to monitor activity on the bus. When you spot the event you’re looking for simply press the Play/Pause button again to stop the waveform.6Wave Inspector ®Navigation and Search: Simplifying Waveform AnalysisApplication Note7/oscilloscopes MarksWhile looking for the source of the problem, you may find numerous areas of the waveform that either warrant further investigation or are indicative of something happening in the device under test that you want to use as a reference point during the rest of your analysis. For example, assume you need to make timing measurements associated with the latency from when a driver presses the Passenger Window Down switch on the driver’s door panel to when the passenger window actually starts to move. The first event you’ll want to find in the acquisition is when the switch was pressed. The next may be when the CAN module in the driver’s side door issues the command to the CAN module in the passenger door. The last event may be when the motor engaged in the passenger door and the window started to move. Wouldn’t it be nice to mark each of these locations on the waveform so you can quickly jump back and forth between the areas of interest for timing measurements? With the Tektronix Wave Inspector ®Navigation Series you can.In Figure 3, Channel 1 is the output of the switch in the driver’s door, channel 2 is the CAN bus, and Channel 3 is monitoring the motor drive in the passenger door.Wave Inspector®Navigation and Search: Simplifying Waveform Analysis Application NoteWe’ve set the oscilloscope up to trigger on the packet of interest by specifying the appropriate Identifier and Data. Next, we’ve used the front-panel Set / Clear Mark button to mark each of the events of interest on the waveform. These user marks are shown as solid white triangles along the top edge in both the upper and lower windows. The rising edge on channel 1 indicates when the switch was pressed. The trigger event is the CAN module in the driver’s door issuing the command and the window beginning to move is the transition on Channel 3. Using the front-panel Previous and Next buttons we can instantly jump between marks to place cursors for quick and easy latency measurements. In Figure 3, we find that the total time from the press of the switch to window movement is 58.8ms, well within the amount ofacceptable delay.Figure 3.Placing marks on the waveform to assist in latency measurements on a CAN bus.8Wave Inspector ®Navigation and Search: Simplifying Waveform AnalysisApplication NoteSearch & MarkIn addition to placing marks on waveforms manually,Wave Inspector ®has the power to search through the entire acquisition and automatically mark every occurrence of a user-specified event. For example, imagine you are capturing laser pulses. The laser fires approximately every 20 µs, with each pulse being only 15 ns wide. You want to look at multiple pulses to characterize their shape and to make precise timing measurements between them, but to navigate from one to the next you need to sift through close to 20 µs of dead time. Then you need to repeat this for every other pulse in the acquisition. Clearly, it would be desirable to be able to move from pulse to pulse instantly without having towaste time “twiddling” a position knob.9/oscilloscopes Figure 3A.Wave Inspector's ®powerful Search capability allows you to find every occurrence of a user-specified event in the acquisition.Previous ButtonNextWave Inspector®Navigation and Search: Simplifying Waveform Analysis Application NoteA very simple search setup that looks for rising edges that cross a threshold of 300mV is illustrated in Figure 4. Marks generated by the search are shown as hollow white triangles along the top edge in both the upper and lower windows. This search resulted in 105 marks being placed throughout the record. Now all you have to do is press the front-panel previous and next buttons to jump from one pulse to the next, no adjustment of zoom scale or positionis required!Figure 4.Wave Inspector®marking every pulse that crosses 300mV in a long acquisition.10Wave Inspector®Navigation and Search: Simplifying Waveform AnalysisApplication NoteWave Inspector’s®Search goes well beyond simple edge searches. Imagine the chip you’re working with has an indeterminate output every so often that’s causing the overall system to crash. You suspect that it’s a metastability issue caused by Setup & Hold violations. In a matterof seconds, you can specify search criteria to have the oscilloscope automatically find every occurrence in the acquisition where setup and hold times you specify were violated. In this case, the part we’re using has published setup and hold times of 12 ns and 6 ns, respectively. To have the oscilloscope automatically find violations of these limits, we simply need to tell it clock is on Channel 1, Data is on Channel 2, set the thresholds, and enter the desired setup and hold times. The oscilloscope then checks the timing relative to every clock edge throughout the entire acquisition and marks the occurrences that violate the specified setup and hold times. In Figure 5, our search resulted in sixviolations. The six events are marked with hollow white11/oscilloscopes Figure 5.Setup & Hold violation search results in six occurrences found.Wave Inspector®Navigation and Search: Simplifying Waveform Analysis Application Notetriangles in the upper window. The lower window is showing a zoomed in view of one of the violations. It’s clear that the narrow negative pulse on the data line is violating the 12 ns setup time.We’ve found the metastability source without having to manually scroll through the waveform and without havingto use cursors to measure anything. You can even perform worst case checks by adjusting the setup and hold times and seeing how many events Wave Inspector®finds. For example, you can set the hold time to zero and then reduce the setup time until only one event is found.1Another powerful search capability provided by Wave Inspector is searching for data in a bus. You can use the front-panel bus buttons to define your signals as an I2C, SPI, CAN, RS-232, or parallel bus. Then the oscilloscope will decode the bus into packets, displaying the informationin a meaningful form. You can trigger on or search for datain the packets. (Requires optional application modules.) 121The MSO4000, MSO2000, and DPO2000 Series oscilloscopes can search for setup & hold violations on every channel in the oscilloscope.Wave Inspector®Navigation and Search: Simplifying Waveform AnalysisApplication NoteWhile this triggering is critical to isolate the time window that contains the problem, it’s highly likely that you’ll need to view bus activity over many packets to understand what’s going on at a system level. The bus search feature enables you to specify packet level criteria and mark every occurrence of it in the record for quick viewing,navigation and analysis. Continuing the earlier CAN example, in Figure 6 we’ve searched for every message in a long acquisition of a CAN bus with the specific Identifier (549) and Data (A1) values we’re interested in.Wave Inspector®found four messages in the acquisition that met the criteria. Again, moving the zoom window from one occurrence to the next is as simple as pressing the previous and next buttons on the front-panel. And because the oscilloscope is decoding the packets for you, you can instantly see all the relevant information without having to manually decode from analog waveforms.In addition to the examples provided above, Wave Inspector®can search for many other types of events. The full list ofsearch capabilities is shown in Table 1.13/oscilloscopes Figure 6.Searching for specific Identifier and Data values in CAN messages.Wave Inspector ®Navigation and Search: Simplifying Waveform AnalysisApplication Note14Table 1.Search events.Search Type DescriptionEdge Searches for edges (rising or falling) with a user-specified threshold level.Pulse Width Searches for positive or negative pulse widths that are >, <, =, or ≠ a user-specified pulse width. RuntSearches for positive or negative pulses that cross one amplitude threshold but fail to cross a second threshold before crossing the first again. Search for all runt pulses or only those with duration >, <, =, or ≠ a user-specified time.LogicSearch for a logic pattern (AND, OR, NAND, or NOR) across multiple waveforms with each input set to either High, Low, or Don’t Care. Search for when the event goes true, goes false or stays valid for >, <, =, or ≠ a user-specified time. Additionally, you can define one of the inputs as clock for synchronous (state) searches.Setup & Hold Search for violations of user-specified Setup and Hold times.Rise / Fall Time Search for rising and/or falling edges that are >, <, =, or ≠ a user-specified time.BusI 2C: Search for Start, Repeated Start, Stop, Missing Ack, Address, Data or Address & Data.SPI: Search for SS Active, MOSI, MISO, or MOSI & MISO.CAN: Search for Start of Frame, Type of Frame (Data, Remote, Error, Overload), Identifier (standard or extended), Data, Identifier & Data, End of Frame, or Missing Ack.LIN: Search for Sync, Identifier, Data, Identifier and Data, Wakeup Frame, Sleep Frame or Errors such as Sync, Parity, or Checksum Errors.RS-232/422/485/UART: Search for Tx Start Bit, Rx Start Bit, Tx End of Packet, Rx End of Packet,Tx Data, Rx Data, Tx Parity Error and Rx Parity Error. Parallel: Search for data value.FlexRay (MSO/DPO4000 Series only): Search for Start of Frame, Type of Frame (Normal, Payload, Null,Sync, Startup), Identifier, Cycle Count, Complete Header Field, Data, Identifier and Data, End of Frame or Errors such as Header CRC, Trailer CRC, Null Frame, Sync Frame, or Startup Frame Errors.Multiple SearchesAn obvious question at this point is,“What if I want to perform another search, but don’t want to lose the results (marks) from my first search?”Simply select the Save All Marks menu selection and you’ll see that the hollow white triangle search marks become filled in, appearing the same as marks placed with the front-panel Set Mark button. These marks are now saved on the waveform and a new search can be performed. You can do this as many times as you like, effectively creating unlimited searching ability. Of course, if you would like to start over with a clean slate you can press the Clear All Marks button to remove all marks from the waveform or you can remove any single mark using theSet/Clear Mark front-panel button.Search Interaction with TriggerTwo other powerful and time-saving capabilities are included in the Search menu: the ability to copy trigger settings to search and copy search settings to trigger. Copying the current trigger settings to the search menu is most useful when you want to search through the acquisition to see if there are any other occurrences of the trigger event in the captured data. Alternatively, copying search settings to the trigger menu is most useful when you’ve found an event in your data and you want to reacquire new data using that event as the trigger criteria.ConclusionModern digital oscilloscopes can capture massive amounts of data. Until now, searching through that data has beena time-consuming and frustrating process. With Tektronix Wave Inspector®Navigation and Search, you can extract the answers you need with efficiency and precision and unlikeany other oscilloscope.Wave Inspector®Navigation and Search: Simplifying Waveform AnalysisApplication Note15/oscilloscopes MSO/DPO4000 Series DPO3000 Series MSO/DPO2000 Series Bandwidth 1 GHz, 500 MHz, 350 MHz500 MHz, 300 MHz, 100 MHz200 MHz, 100 MHzChannels (analog) 2 or 4 analog 2 or 4 analog 2 or 4 analogChannels (digital)16 digital (MSO series)–16 digital (MSO series)Record Length10 M 5 M 1 M(All Channels)Sample Rate 5 GS/s*, 2.5 GS/s 2.5 GS/s 1 GS/sDisplay10.4 in.

Working Remotely with Tektronix Oscilloscopes ––TECHNICAL BRIEFThere are several approaches you can take to Array work remotely with Tektronix oscilloscopes. The available techniques differ somewhat between instruments that run the Windows operating system and instruments that do not. This guide is designed to help you interface with your oscilloscope without needing to physically interact with the instrument after the initial setup. This document applies to most Tektronix oscilloscopes that do not have a PC operating system installed.Oscilloscopes that run the Windows operating system offer different alternatives for working remotely. The Technical Brief “Working Remotely with Tektronix Oscilloscopes Running the Windows Operating System”offers information on interfacing with Windowsoscilloscopes.2 | | 3Figure 1. The rear panel of a 6 Series MSO includes Ethernet LAN and USB device interfaces available for remote access.REMOTE CONTROL USING BUILT-IN WEB SERVERMany modern Tektronix oscilloscopes feature a built-in webserver called e*Scope. On the 4 Series MSO, 5 Series MSO, and 6 Series MSO, e*Scope is an easy to set up, real-time display and interface that runs on a web browser as if you were at the instrument with a mouse and keyboard. Anyone with the IP Address can simultaneously access and control the oscilloscope.On many entry-level and previous generation oscilloscopes, e*Scope is a remote User Interface that allows you to quickly see a snapshot of the oscilloscope display and make adjustments to settings and measurements. Examples of these oscilloscopes include TDS3000B, TDS3000C, DPO2000, MSO2000, DPO3000, MSO3000, MDO3000, DPO4000, MSO4000, MDO4000, 3 Series MDO and more.SETTING UP THE OSCILLOSCOPEe*Scope requires a network connection between a modern web-browser and an oscilloscope. The web-browser may be running on a computer, smartphone, or other device. The network connection can be a direct connection with an Ethernet cable, a Local Area Network connection with a network switch or router, over a VPN, or via an externally accessible IP Address. You may need your IT Department’s assistance or permission to connect the instrument to a network.When the oscilloscope is connected to a network that you can access, you need to find the oscilloscope’s IP Address. This istypically in a Utility or I/O configuration menu.Figure 2. Example of the I/O Menu on a 6 Series MSOIn the I/O settings, you can find an automatically configured IP address or set a static IP address. Make note of the IP addressto be ready to enter it into your web-browser’s address bar.Figure 3. Example of the LAN Settings on a 6 Series MSOACCESSING THE OSCILLOSCOPE THROUGH A WEB BROWSEREnter the oscilloscope’s IP Address into the address bar of a web-browser. When you navigate to that IP Address as if it were a website, the oscilloscope will present you with a Home page with several connection and configuration options, including a link toe*Scope. Click the link to e*Scope to connect to the oscilloscope for remote control.Figure 4. Example of the Home page connected to a 6 Series MSOFILE SHARINGNo file sharing method is built-in to e*Scope. The File Sharing section of this guide explains a method of mounting network drives that works nicely with most e*Scope instruments.TROUBLESHOOTING AND SUPPORTFor additional instrument-specific guidance on e*Scope, please refer to the Primary User Manual or Online Help Manual for that oscilloscope model on . You can also contact Tektronix technical support through /support orby asking your local Tektronix support contacts.4 | | 5TEKSCOPE PC WAVEFORM ANALYSIS SOFTWARE AND REMOTE SCOPE DATA ACQUISTIONTektronix offers a PC-based analysis application called TekScope that can allow you to analyze previously-saved waveforms for free, without connecting to an oscilloscope. You can also connect to one or more oscilloscopes as a paid service to pull real-time data from the remote scopes. You can access this software and see more details at .This software allows engineers to collaborate withoutnecessarily having to share physical access to an oscilloscope and provides increased flexibility in each individual’sworkflows. Consider the following examples of workflows that this software enables:• One engineer can take data in a lab and send it to several other engineers with this free software installed, and everyone can independently make measurements.• An engineer can spend one day in an instrumentation lab to collect a large set of data, but the rest of the week at their desk or out-of-office doing analysis.• As with other remote control options, users with the “Multi-Scope Analysis” option can connect directly to networked oscilloscopes to adjust instrument settings, collect newdata and transfer waveforms all from the TekScope interface to be viewed and analyzed in a centralized user interface.The TekScope interface duplicates the features and user-friendly interface of 4/5/6 Series MSOs. Any engineers that are familiar with those oscilloscopes will feel right at home with this software, and any unfamiliar users should find the interfaceeasy to pick up.Figure 5. TekScope software uses the same user interface as the 4, 5 and 6 Series MSOs. The basic analysis package is free. With the premium Multiscope option it can collect data from two oscilloscopes at once.TekScope supports importing waveforms in a variety of formats from a variety of vendors. Typical oscilloscope measurements, math capabilities, plots, cursors, etc. are available for free, while application-specific analysis features are available as paid services. For a summary of features and options, please see /#/packages .6 | FILE SHARINGEvery modern Tektronix oscilloscope has the capability to save Waveforms and Setups to internal and external storage. Habitually saving your work can make it easier to collaborate on-the-fly and look back at old projects. Anything from a TDS3000C oscilloscope to a 4 Series MSO to a DPO70000SX can save waveforms to a USB drive, for example. Many oscilloscopes can also be connected as a client to network drives for remote file management.Most recent non-Windows oscilloscopes, including DPO2000, MSO2000, DPO3000, MSO3000, MDO3000, DPO4000, MSO4000, MDO4000, 3 Series MDO, 4 Series MSO, 5 Series MSO, and 6 Series MSO have a File Utilities system through which you can mount a network drive as well.SAVING AND RECALLING FILESBoth direct and networked file management options can usually be accessed in the File menu of an oscilloscope. In the following example from a 6 Series MSO, the Recall selection can be used to load waveforms, setups, “sessions” (an all-in-one save type) and masks. The Save and Save As selectionscan be used to store screen captures, waveform data, setups, sessions and generate reports. The File Utilities selection is where you can connect to a network drive or do things like copy and paste, delete, and rename files on the oscilloscope’slocal memory.Figure 5. Example of the File menu on a 6 Series MSO.Figure 6. Example of saving a Session file on a 6 Series MSO.In the Save As menu, the save location can be altered with the “Browse” button. At the very least, the oscilloscope’s local memory (in this example, the C drive) will be accessible. If a USB Drive or Network Drive is connected, those locations will also appear as options.PREPARING A NETWORK DRIVE ON A WINDOWS PCConnecting to a Network Drive is often simple to configure on the oscilloscope but can sometimes be difficult to configure from a security and networking standpoint. The first step isto make some file, folder or directory accessible from a host server or computer to a network that the oscilloscope is on as well. The next step is to either Mount the network driveon a non-Windows oscilloscope or browse to it through File Explorer on a Windows Oscilloscope.As an example, to share from a Windows 10 PC, you can right click on a folder you wish to make your network drive, go to Properties, and then Sharing. In the new dialog that pops up, called Network Access, the list of Names are the users whose credentials can be used to access this shared folder. In other words, if left as the default, only your username and password can be used to access this new network drive, but you can optionally add more users or open the folder up to everyone on the network.When user access is configured as you like it, press Share in the Network Access dialog to finally host the network drive.The following image is an example of a simple configuration. Figure 7. Example of creating a shared folder on Windows 10. | 7MOUNTING THE NETWORK DRIVE FROM THE OSCILLOSCOPETo access this folder on a networked non-Windows oscilloscope, you can now go to File Utilities and enter the required fields. The following image shows a typical example of how each field maps to the folder settings in the previous image. An IP Address can be used instead of the server name.A more detailed walkthrough for this example is available at / support/faqs/how-do-i-set-network-drive-my-5-series-mso-or-6-series-mso.Figure 8. Example of mounting a network drive on a 6 Series MSO PROGRAMMATIC CONTROLNearly every Tektronix oscilloscope with an external communication port (e.g. GPIB, USB, Ethernet) can be controlled with remote commands. This is a powerful, flexible and scalable method of remotely controlling your instrument and automating measurements. There is a higher upfront development cost to get up and running when compared with the other methods available to you, but basic scripting is surprisingly easy to accomplish.Tektronix instruments use SCPI style commands which are industry standard ASCII strings and therefore language-agnostic, which means any language and environment can be used for control. Commonly used languages for this include Python (with PyVISA), MATLAB (with the Instrument Control Toolbox), LabVIEW, and the C-family.PROGRAMMING RESOURCESGuides on programmatic control and the variety of remote commands with detailed descriptions can be found in the instrument’s Programmer’s Manual. You can find this on , easily accessible by searching for your model number and filtering by“Manual” and then by “Programmer.”Figure 9. Example of searching for a programmer’s manual8 | Examples of scripts can be found around the internet. Tektronix resources include:• Tektronix online forum at /viewtopic.php?f=580&t=133570• Tektronix GitHub at /tektronix.In addition, the Tektronix Support YouTube channel has a video of getting started from the ground-up for free in Python here: /watch?v=W5Brxiwnp5g.INSTALL A VISAIt is important to be aware of VISA (Virtual Instrument Software Architecture) applications and to have one installed. VISA is an I/O API that is largely industry standard, with many Test and Measurement vendors supplying their own implementation. See /hardware-support/ni-visa-keysight-visa-tekvisa.html for a few examples. While in general which VISA you use should not matter, it sometimes does, and sometimes installing multiple VISAs can cause conflicts.Some additional standard protocol specifications that commonly manage I/O on top of VISA are USB-TMC forUSB control and VXI-11 for TCP/IP control. Some users choose to use Raw Sockets instead of VXI-11 based control over Ethernet.CONTROL WITH USB AND UTILITY APPLICATIONSMany oscilloscopes can be controlled over USB via theirUSB-B port. While USB control often results in lower throughput and latency than Ethernet-based control methods, USB provides a network-less and convenient connection. Often USB control uses SCPI commands, as discussed inthe Programmatic Control section of this guide, with a GUI on top. Three notable examples of applications that support USB connections are TekScope Utility, OpenChoice Desktop, and Keithley KickStart.TEKSCOPE UTILITY FREEWARETekScope Utility is a free utility application written by a Tektronix engineer with a simple, usable GUI with accessto commonly scripted features such as screenshot transfer, measurement logging, action-on-trigger, and waveformdata transfer. This utility supports most recent and several older Tektronix oscilloscopes range from entry-level toultra-high-performance.TekScope Utility freeware is available at / viewtopic.php?t=140451.Figure 10. Sample screenshot of TekScope UtilityOPENCHOICE DESKTOPOpenChoice Desktop is a free official utility application provided by Tektronix that supports the most common simple behaviors like screenshot and waveform transfer on many previous generation oscilloscopes.OpenChoice Desktop is available at /oscilloscope/tds210-software/tektronix-openchoice-desktop-application-tdspcs1-v26.KEITHLEY KICKSTARTKeithley KickStart is an inexpensive official software that supports a variety of Tektronix and Keithley instruments. Common simple behaviors on oscilloscopes are supported, but KickStart provides many built-in data collection behaviors on Keithley DAQs, SMUs, DMMs, and Power Supplies. Engineers working with Tektronix and Keithley instruments in tandem should consider Kickstart.Kickstart is available at /keithley-kickstart.There are many approaches to controlling and getting data from Tektronix oscilloscope that run the Windows operating systems. The approach you take depends on your application and may also depend on your company’s policies. | 9Find more valuable resources at Copyright © Tektronix. All rights reserved.

泰克示波器的使用方法泰克示波器是一种用来测量电信号的仪器，广泛应用于电子工程、通信、计算机科学等领域。

它能够将电信号转换成图形显示，帮助人们分析信号的特征和性质。

本文将详细介绍泰克示波器的使用方法。

首先，泰克示波器的前期准备工作非常重要。

我们需要将示波器连接到待测信号的源头，确保信号传输的稳定和可靠。

通常情况下，示波器有两个输入通道，可以同时测量两路信号。

我们需要使用连接线将待测信号源与泰克示波器的输入通道连接起来。

在连接过程中，请务必确保连接线的质量良好，避免产生干扰和噪声。

接下来，我们需要对泰克示波器的设置进行调整。

首先是电压范围的调整。

我们需要根据待测信号的幅值范围来设定示波器的合适量程。

通常情况下，泰克示波器提供了多档量程可供选择，分别对应不同的信号幅值范围。

我们可以根据待测信号的预估幅值来选择相应的量程。

接着是时间基准的调整。

示波器的时间基准用来设定X轴的时间刻度。

根据待测信号的频率和时间长度，我们可以选择适当的时间基准，以便观察到信号的波形特征。

通常情况下，示波器提供了多个时间基准可供选择，包括微秒、毫秒、秒等。

我们可以根据需要灵活调整时间基准。

在设置完电压范围和时间基准后，我们需要对泰克示波器的触发功能进行配置。

触发功能能够使示波器只显示待测信号的一部分波形，以便我们能够更清晰地观察信号的特征。

触发功能包括触发源、触发方式和触发电平等设置。

触发源通常可以选择信号源或外部触发，触发方式可以选择边沿触发或脉冲触发，触发电平可以设置为上升沿、下降沿等。

我们可以根据待测信号的特点和需要来进行相应的触发配置。

接下来就是正式进行泰克示波器的测量操作了。

我们可以通过调整泰克示波器上的各种旋钮和按钮来获取我们需要的波形图像。

首先，我们可以通过调整竖直位置旋钮来使波形在屏幕上垂直居中。

然后，我们可以通过调整水平位置旋钮来使波形在屏幕上水平居中。

接着，我们可以通过调整增益旋钮来改变波形的放大倍数，以便更清晰地观察信号的细节。
