BOONTON ELECTRONICSa Wireless Telecom Group Company4400A/4500A MANUAL ADDENDUMApplies to Instruction Manual Model 4500A RF Peak Power Meter /Analyzer, Model 4400A RF Peak Power Meter, Part Number 98404700A, revised 09/97.Effective for Control Software Revision 20020511 and later.1.0 NEW FEATURES1.1 Peak Sensor Temperature CompensationWhen used with a peak sensor that contains a valid temperature compensation table, the model 4400A and 4500A Peak Power Meters can provide temperature compensated power measurements. The default mode for temperature compensation is active. The Chan n > Calibration>Temp Comp menu box will be visible with “Sensor Tbl” displayed. To turn off temperature compensation press the menu button and “Off” will be displayed. The “Off” setting is volatile and not preserved through power cycles or major mode changes. If the sensor in use does not have a temperature compensation table the Temp Comp menu box will not appear at all.The Spcl>Chan n Sensor report will include the message “Sensor has Temperature Compensation Table” when appropriate. The Spcl>Servicing>Configuration report shows TC system status if either channel has a sensor with a valid table. The format of this messageif present is:TC System Status 1:[err code] #### 2:[err code] ####The error codes are:0 No error.145 TC # of Temps Err Table parameter error146 TC # of Powers Err Table parameter error147 TC Interp Err Table interpolation error148 TC Expand Err Table expansion error149 TC Extend Err Table extension error150 TC Chksum Err Table read checksum error151 TC Table Length Error152 TC Temp Value Err A temperature value is out of range98404706A1 1981153 TC Temp Non-mono A temperature array is non-monotonic154 TC Power Value Err A power value is out of range155 TC Power Non-mono A power array is non-monotonic156 TC Corr Value Err A correction value is out of range Use CH1 or CH2 to specify to which channel the following temperature compensation related GPIB commands apply:TCON Turn on temperature compensation if available. If not, ignore.TCOFF Turn off temperature compensation. This is a volatile setting ifavailable.compensationis1.2 Sensor Auto-calibration File RetentionSensor auto-calibration files are now saved by channel as .AC1 and .AC2 files in non-volatile (flash) memory. This avoids the need to perform auto-cal every time a sensor is removed and replaced by a different one, provided the sensors are known to the channel(s) involved. When a sensor is plugged-in a search is made to find an existing auto-cal file. If one is found, it is installed. If not, the “Needs Auto-cal” message will appear. When auto-cal is performed the existing file is overwritten with the new result. If no previous file exists, one is created. Sensor filenames have the form SEN#####.AC n, where ##### is the serial number and n is the channel number.The file directory system is expanded to display auto-calibration files in flash memory as well as the previous files on the floppy disk. The Utility>Disk>Flash Disk path lists sensor auto-cal files by channel. The Select File <> menu contains a sequence number which refers to the position of the file in the list. The selected file is shown in RED and may be deleted by pressing the menu button next to the “Delete” box. Deletion of files must be confirmed or cancelled.There are no GPIB operations on the file directory.1.3 Color *.bmp File of DisplayThe Hardcopy section now includes a color *.bmp file of the current display that can be saved to the floppy disk, sent to the COM1 port or the GPIB. To select this feature set the Util>Hardcopy>Device menu to “Plotter”. Then select Util>Hardcopy>Model “.BMP”.Choose the Plot Label, Output Port and File Select number if the output is the floppy disk. Graph & Text is not applicable. Note that the “IEEE-488” output selection applies to the listen only (lon) GPIB addressing mode only. For controller directed GPIB output298404706Asee below. Press the PLOT key to send the file to the selected output. The .bmp extension is added to the floppy disk file directory to allow viewing the filenames saved on disk. The GPIB commands for controller directed return of the .bmp file contents are:Send the sequence PLOTTER PLOT.BMP to select the bit-map mode.Send TKPLOT to set the talk mode that returns the file when addressed to talk.The GPIB commands to send the plot file contents to an output other than the GPIB are:Send the sequence PLOTTER PLOT.BMP to select the bit-map mode.Send PLOTSER1, PLOTCOM1, PLOTLPT1 or PLOTDISK to select the output.{Use PLOT488 only with the front panel PLOT key manually to send in the talk only (ton) mode to a listen only (lon) device}.For PLOTDISK send FILENO ## to select a filename.Send PLOT to simulate pressing the PLOT key to send the file to the selected output.1.4 External Trigger Input CalibrationA provision to zero and calibrate the external trigger inputs has been added to provide better accuracy for voltage measurements made with the trigger inputs. The following procedure is used to calibrate each external trigger input:Set Time>Timebase to “5 ms/Div”Set Trig>Trig Mode to “Auto”Select the external trigger input in the Trig>Trig Source menu corresponding to the selected measurement channel (CH1 to 1EXT or CH2 to 2EXT).Set the Chan#>Extensions>Display to “Trig” (Trigger View Mode)Set the Chan#>Vert Scale to 1.00 V/DivSpcl>Servicing>Cal Mode “On”SettheWith Cal Mode “On” two boxes labeled Ext Trig Zero and Ext Trig Cal will appear in the Chan#>Extensions menu. Ext Trig Zero will have a bright “Start” label.With no input to the selected external trigger input, press the menu button for Ext Trig Zero “Start”. The input will be zeroed and the Ext Trig Cal “Start” label will be bright.With +3.00 volts applied to the selected external trigger input, press the menu button for Ext Trig Cal “Start”. The input will be calibrated for 3 divisions of deflection at 1 V/Div.Set the Spcl>Servicing>Cal Mode “Off”The results of the calibration are stored in non-volatile memory with file extension .TRV. Absent a file, default data is supplied automatically and simulates the existing software. External trigger level calibration is not available on the GPIB.398404706A1.5 UNDIM Command.A GPIB command, UNDIM, is added to reset the screen saver without touching the panelor re-loading the color table. This is helpful in remotely controlled applications.2.0 Changes2.1 Instrument Setup Save/Recall change.The instruments setup save and recall system has been modified to save a binary file instead of an ASCII file. The binary file is smaller and more comprehensive and is identical to the internal save/recall format. The new file has the extension .ISU. For customers with existing .INS files the ability to read an .INS file is still present, but new features will not be available using this method. Existing files should be converted by reading the .INS files and saving them as .ISU. The file directory is modified to display .ISU files. The GPIB commands are not affected.2.2 GPIB command *OPT? change.An installed hardware options list has been appended to the *OPT? GPIB command format previously used. For example, a single channel instrument with Option 04 hardware installed and a sensor plugged-in returns:1,1,0,0,42.3 Configuration report change.Installed options are now identified in the Configuration Report. For example:The Spcl>Servicing>Configuration Report for Option 04 installed reports:Opt 04 – Trigger Delay by Events installed2.4 Sensor Temperature Reporting change.Sensor auto-cal temperature and current temperature readings have been moved from the Utility>Report to the Spcl>Ch 1 Sensor>Report and Spcl>Ch 2 Sensor>Report.498404706A3.0 Corrections1. Remove glitches that occur when in Triggered mode (as opposed to Auto) and certaincommands are executed. Also, measurement traces can now be moved and re-scaledwhen Waiting for Trigger on the slow time bases.2. Calculate the auto-measure parameter “OFF TIME”. This function has always beenenabled but there was no calculation method included.3. Correct an overflow error in the cal table expansion that overwrites the first positionof the channel 2 table when channel 1 is expanded. This may cause the channel 2PDF to not appear.4. GPIB command TKBMEAS now reports the sign of Pk/Avg ratio correctly.5. Marker math mode changes now occur immediately even in wait for trigger.6. When both markers are in trigger view mode the marker math functions MK1-MK2,MK2-MK1, MAX-MIN and MIN-MAX are computed as voltage difference andappear in the middle window with voltage difference units. The PK/AVG mode is notrecognized in trigger view mode but is not an error. This correction also appears inthe parameters of GPIB commands TKMEAS, TKBMEAS and TKUNITS whenappropriate.7. The trigger pointer is now removed when the direct set of a statistical mode occurs.8. Restore the legacy GPIB command MKDELTA to set the marker math to powerdifference in the linear units mode only. This command was deleted by mistake in the“A” series.9. Update the RUN/STOP message in the recall stored setup function to avoid out ofsync messages.10. Change the linear mode reference lines to track vertical offset in “divisions” ratherthan watts, which is incorrect.Revised 20020513598404706A。

英语作文如何保存文件How to Save Files: A Comprehensive Guide。

Introduction:In today's digital age, saving files has become an essential skill. Whether it's for work, school, or personal use, knowing how to save files properly ensures that important data is stored securely and can be easily accessed whenever needed. This article aims to provide a comprehensive guide on how to save files effectively.1. Organizing Your Files:Before saving any file, it is crucial to establish a well-organized system. Create folders and subfolders that reflect the type of files you will be saving. For instance, you can have separate folders for work-related documents, personal photos, and educational materials. This organization will make it easier to locate files later on.2. Naming Conventions:Developing a consistent naming convention is essential for efficient file management. Use clear and descriptive names that accurately represent the content of the file. Avoid using generic names like "Document1" or "Untitled." Instead, opt for specific titles that provide context at a glance. For example, if you are saving a report on climate change, name the file "Climate Change Report 2022."3. Choosing the Right File Format:Different file formats serve different purposes. Consider the purpose of the file and select an appropriate format accordingly. For text-based documents, such as essays or reports, saving them as PDFs ensures that the formatting remains intact across various platforms. On the other hand, images should be saved in formats like JPEG or PNG, while videos require formats like MP4 or MOV.4. Saving Locally vs. Cloud Storage:When it comes to saving files, it is essential to consider both local storage and cloud storage options. Local storage refers to saving files on your computer's hard drive or an external storage device, while cloud storage involves saving files on remote servers accessible via the internet. Utilizing both options provides an extra layer of security and ensures accessibility from anywhere.5. Regular Backups:To safeguard your files from potential data loss, it is crucial to create regular backups. This can be done by copying important files to an external hard drive or using cloud backup services.

DataGuard基本概念Dataguard是ORACLE 推出的一种高可用性（HIGH AVAILABLE）的数据库方案，在8i之前称之为standby database，从9i开始，正式更名为Dataguard，它是在主节点与备用节点间通过日志同步来保证数据的同步，可以实现快速切换与灾难性恢复. Dataguard只是在软件上对数据库进行设置,并不需要额外购买任何组件，它能在对主数据库影响很小的情况下，实现备数据库的同步，而主备机的数据差异只在在线日志部分，所以被不少企业作为了数据容灾方案.一、DataGuard的发展史 ORACLE 从7。

3 开始支持standby database.7。

3。

x-8.0.x 需要手工拷贝所有归档日志并手工同步，从ORACLE815 开始，开始支持多节点复制，并实现了自动同步，但是这种同步是数据异步模式的，可能引起数据丢失.从ORACLE9i开始,备用服务器已经换了一种新的称呼，叫数据保护(DATA GUARD)，在这种模式中,开始支持三种不同的数据保护模式，并开始采用LGWR 对数据的传送而不是以往的ARCH，并增加了一个新的后台进程叫DMON 监控数据的同步，支持多达9个节点的同时复制。

从920开始，还开始支持物理与逻辑备用服务器。

二、运行要求1、主机运行在归档模式下2、主备数据库的版本必须一样,操作系统必须一样，但版本可以不同。

Redis源码剖析之内存淘汰策略（Evict）Redis作为⼀个成熟的数据存储中间件，它提供了完善的数据管理功能，⽐如之前我们提到过的和今天我们要讲的数据淘汰(evict)策略。

在开始介绍Redis数据淘汰策略前，我先抛出⼏个问题，帮助⼤家更深刻理解Redis的数据淘汰策略。

1. 何为数据淘汰，Redis有了数据过期策略为什么还要有数据淘汰策略？2. 淘汰哪些数据，有什么样的数据选取标准？3. Redis的数据淘汰策略是如何实现的？何为Evict我先来回答第⼀个问题，Redis中数据淘汰实际上是指的在内存空间不⾜时，清理掉某些数据以节省内存空间。

虽然Redis已经有了过期的策略，它可以清理掉有效期外的数据。

但想象下这个场景，如果过期的数据被清理之后存储空间还是不够怎么办？是不是还可以再删除掉⼀部分数据？在缓存这种场景下这个问题的答案是可以，因为这个数据即便在Redis中找不到，也可以从被缓存的数据源中找到。

所以在某些特定的业务场景下，我们是可以丢弃掉Redis中部分旧数据来给新数据腾出空间。

如何Evict第⼆个问题，既然我们需要有淘汰的机制，你们在具体执⾏时要选哪些数据淘汰掉？具体策略有很多种，但思路只有⼀个，那就是总价值最⼤化。

我们⽣在⼀个不公平的世界⾥，同样数据也是，那么多数据⾥必然不是所有数据的价值都是⼀样的。

所以我们在淘汰数据时只需要选择那些低价值的淘汰即可。

所以问题⼜来了，哪些数据是低价值的？这⾥不得不提到⼀个贯穿计算机学科的原理局部性原理，这⾥可以明确告诉你，局部性原理在缓存场景有这样两种现象，1. 最新的数据下次被访问的概率越⾼。

2. 被访问次数越多的数据下次被访问的概率越⾼。

这⾥我们可以简单认为被访问的概率越⾼价值越⼤。

基于上述两种现象，我们可以指定出两种策略 1. 淘汰掉最早未被访问的数据。

2. 淘汰掉访被访问频次最低的数据，这两种策略分别有个洋⽓的英⽂名LRU(Least Recently Used)和LFU(Least Frequently Used)。

Contact SMC for specific drawings.3 Installation3.1 InstallationWarning• Do not install the product unless the safety instructions have been read and understood. 3.2 EnvironmentWarning• Do not use in an environment where corrosive gases, chemicals, salt water or steam are present.• Do not use in an explosive atmosphere.• Do not expose to direct sunlight. Use a suitable protective cover.• Do not install in a location subject to vibration or impact in excess of the product’s specifications.• Do not mount in a location exposed to radiant heat that would result in temperatures in excess of the product’s specifications. 3.3 PipingCaution• Before connecting piping make sure to clean up chips, cutting oil, dust etc.• When installing piping or fittings, ensure sealant material does not enter inside the port. When using seal tape, leave 1 thread exposed on the end of the pipe/fitting.• Tighten fittings to the specified tightening torque. 3.4 LubricationCaution• SMC products have been lubricated for life at manufacture, and do not require lubrication in service.• If a lubricant is used in the system, refer to catalogue for details. 3.5 Air supplyWarning• Use clean air. If the compressed air supply includes chemicals, synthetic materials (including organic solvents), salinity, corrosive gas etc., it can lead to damage or malfunction.Caution• Install an air filter upstream of the valve. Select an air filter with a filtration size of 5 μm or smaller.3.6 MountingCaution• Ensure gaskets are in good condition, not deformed and are dust anddebris free.• When mounting valves ensure gaskets are present, aligned and securely in place. For screw mount type (SX11-), tighten the valve mounting screws (M3 x 0.5) to the recommended tightening torque of 0.5 N ∙m to 0.7 N ∙m. 3.6.1 Installation of quick disconnect type (SX12-)Figure 3.3 Installation - continued3.6.2 Valve installation on manifold baseQuick disconnect type (SX12-) Screw mount type (SX11-)Electrical entry can be on the either side, right or left.Figure 4.3.7 Electrical circuitCaution• Using a surge voltage suppressor such as diode and surge absorber for the electric circuit may cause malfunction, such as delay in response, abnormal heat generation or burn out of the coil. Please consult with SMC when using it.• Use elements that are resistant to the surge voltage of 300 V for the output.• If a valve type without suppression is used, suppression must be provided by the host controller as close as possible to the valve.• Make sure that no excessive force larger than 15N is applied to the lead wires as it may cause the wires to break.• Use electrical circuits which do not generate chattering in their contacts.Figure 5.3.8 Countermeasure for surge voltageCaution• At times of sudden interruption of the power supply, the energy stored in a large inductive device may cause non-polar type valves in a de-energised state to switch.• When installing a breaker circuit to isolate the power, consider a valve with polarity (with polarity protection diode), or install a surge absorption diode across the output of the breaker. 3.9 Extended period of continuous energizationWarningIf a valve will be continuously energized for an extended period of time, the temperature of the valve will increase due to the heat generated by the coil assembly. This will likely adversely affect the performance of the valve and any nearby peripheral equipment. Therefore, if the valve is to be energized for periods of longer than 30 minutes at a time or if during the hours of operation the energized period per day is longer than the de-energized period, we advise using a 4 W type valve (SX1 -(D,H,M) ) or using other valve types as listed below.Powerconsumption [W] Model number Operating condition (at 24 VDC)80 W SX1 -(A,E,J)Use with an energy saving driver with holding voltage of 3 VDC to 6 VDC.40 W SX1 -(B,F,K)Use with an energy saving driver withholding voltage of 4 VDC to 8 VDC.10 WSX1 -(C,G,L)Use with an energy saving driver withholding voltage of 8 VDC to 16 VDC.

Actual performance may vary depending on the features of the model and the spec of devices. T ypically, 15MB XVL files can represent a CAD file of approximately 1GB or larger.I have XVL files copied or downloaded via iT unes and they are shown in the file list, but themessage ”iXVL Player cannot load an XVL which is not processed by iXVL Publisher.” appears to result in an error to open the files.iXVL Player can show only XVL files output by iXVL Publisher. XVL files output by XVL Converter or XVL S tudio can be shown on iXVL View.Although the XVL file was copied by iT unes, it is not displayed on the iXVL Player file list.Only XVL files with the extension .xv2 and .xv3 are supported by iXVL Player. xv2 and .xv3 is the extension used by P-XVL / V-XVL / U-XVL files. .xv0 files must be converted to .xv2 or .xv3 before viewing with iXVL Player.iXVL Player fails to open the file.This may occur when the XVL file is too large to process. If you encounter this, we recommend using XVL S tudio to create smaller files (e.g. sub-assemblies) from the larger file.Although I was able to open the file, not all of the data is displayed.This may occur in XVL files including a shape with an extremely large amount of display polygons.There is not solution at this time and we recommend using CAD system or XVL S tudio to divide the model into smaller segments.I restored iPad / iPhone from the backup file and the file name disappeared.When iPad / iPhone is restored from the backup file or the free storage space is running short, the XVL files with URLs downloaded from the Web site will disappear from the file list. This is the currentspecifications of iXVL Player.
