Agilent Technologies 35670A Dynamic Signal AnalyzerProduct OverviewThe Agilent 35670A is a portable two- or four-channel dynamic signal analyzer with the versatility to be several instruments at once. Rugged and portable, it’s ideal for field work. Yet it has the performance and functionality required for demanding R&D applications. Optional features optimize the instrument for troubleshooting mechanical vibration and noise problems, characterizing control systems, or general spectrum and network analysis.Take the Agilent 35670Awhere it’s needed!Whether you’re moving an instrument around the world or around the lab, portability is a real benefit. Small enough to fit under an airplane seat, the 35670A goes where it’s needed. But there’s more to portability than size. Like a nominal 12- to 28-Volt DC power input and self-contained featuresthat do not require externalhardware, such as built-inpiezoelectric integrated circuitpower supply, analog trigger andtachometer inputs, and optionalcomputed order tracking.Versatile enough to beyour only instrument forlow frequency analysisWith the 35670A, you carry severalinstruments into the field in onepackage.

Themaximum powerrequirement is350 VA.34Laboratory-qualitymeasurements in the fieldObtain all of the performance of your bench-top analyzer in a portable instrument.Ease-of-usePortability, versatility, and perfor-mance are valued attributes, but to be really valuable an instrument must also be easy to use. The 35670A has a friendly front panel,plus online help that’s alwaysavailable to answer your questions.An interactive measurement state lets you configure the instrumentsetup from a single display.Two spectrums of road induced vibration measured at different speeds are comparedusing the front/back modeof the Agilent 35670A.FFT-based spectrum analyzers, such as the 35670A, are ideal for measuring the spectra of low-frequency signals like speech or mechanical vibration. Transient components,usually missed with swept-frequency analyzers, are easily measured and displayed at speeds fast enough to follow trends. The 35670A has both the performance and features required to take full advantage of this technology.16-Bits for High PerformanceWith a 16-bit ADC (90 dB typical dynamic range) and a real-time bandwidth of 25.6 kHz, you can be sure nothing will be missed. Resolve signals using 100 to 1600 lines resolution, or for really close-in analysis, use frequency zoom to resolve signals with up to 61 µHz resolution. Use time or RPM arming to develop waterfalls of sequential vibration spectra for trend analysis or for an overview of device vibration.Power and Linear SpectrumsMatch your spectrum measurement mode to the signal being tested. Use linear spectrum analysis to measure both the amplitude and phase of periodic signals such as the spectra of rotating machinery.Power spectrum analysis is provided for averaging nonrepetitive signals.AveragingVarious averaging modes let you further refine spectrum analysis measurements. Time averaging extracts repetitive signals out of the noise while rms averagingreduces the noise to its mean value.Exponential averaging, available for both time and rms averaging, is useful for reducing the noise while following changing signals—tracking the resonance shifts in a fatiguing structure for example.Spectrum Analysis5Time DomainUse your spectrum analyzer as alow-frequency oscilloscope or view signals in the time and frequency domains simultaneously. (Note: anti-alias filters can be switched off.) Special markers for time-domain data facilitate extraction of key control system performance parameters: overshoot, rise time,setting time, and delay time.Data TableUse a tabular format to keep track of key frequencies in the spectra of rotating machinery. The amplitude and frequency of the signal and a 16-character entry label field are listed for each selected point.Automatic Units ConversionDisplay vibration data in the units of your choice. Select g, m/sec 2, in/sec 2, m/s, in/s, m, mil, inch, Kg, lb, N, dyn,or pascals as appropriate for your application.The instrument automatically converts frequency-domain data from specified input transducer units to the units you select for display. For example, accelerometer data is automatically converted and displayed as mils when mils are selected. Of course, dB, dBV, dBm and volts are available for electrical applications.MarkersMarkers streamline analysis by helping you select and display specific data. Marker functions include marker to peak, next right peak, and coupled markers for selecting points in multiple data displays. Markers readouts are absolute or relative to your selected reference.Special MarkersThree special marker functions facilitate analysis of your spectral data. Sideband markers aid analysis of modulation signals. Use thisfunction to quickly locate sidebands in the complicated spectra of rotating machines. A band-power marker reads the total power in a selected band of frequencies and a total harmonic distortion marker lets you calculate total harmonic distortion without including the effects of noise.Measurement results at key frequencies can be labeled and listed using data table.Harmonic markers are used to calculate the THD of a signal without including the effects of noise.Simultaneousdisplay of frequency and time domain data facilitates analysis of gear mesh vibration.6The 35670A has the flexibility to make measurements of both electrical networks and mechanical devices. FFT-based network analysis is fast enough to allow real-time adjustments of circuit parameters while the swept-sine option provides exacting measurements over more than six frequency decades, and a 130 dB dynamic range.SourceSelect the optimum stimulus for each application—random noise,periodic chirp, pink noise, fixed sine, burst random, and burst chirp.For zoomed network analysismeasurements, the source is band-translated to match the zoom span at frequencies up to 51.2 kHz. An optional arbitrary source lets you test your product using real-world signals. A ±10 Volt DC source offset facilitates tests of control systems.Impact TestingForce and exponential windows allow impact testing for modal and structural analysis. Quality measurements are ensured using preview and accept/reject during averaging. A 4 mA constant current transducer power supply is built-in for true portability.Frequency ResponseMeasurementsLimits are used for go/no go testing in production. The response of an accelerometer is being checked inthis example.Characteristics of a selected resonance are automatically calculated from an impact measurement using the frequency and damping marker.LimitsTest network measurements against preset limits. Up to 800 separate line segments are available for setting upper and lower limits.Limits are also used for testing spectrum measurements.Four Channels (option AY6)Test up to three devicessimultaneously with a four-channel 35670A. Channel one is the common reference channel and two, three,and four are the response channels.Alternatively, select channels one and three as reference channels for two totally independent network measurements. See option AY6 description for more information.7MarkersA frequency and damping marker provides the resonant frequency and the damping ratio of single-degree-of-freedom frequency response measurements.Gain and phase margin markers extract key frequency-domain stability data from frequency response measurements of control systems.Signal Injection for Control LoopsUse one of three Agilent signal injection devices for testing control loops. The 35280A summing junction provides convenient DC to 1 MHz signal injection for most control loops. Use the 35281A clip-on transformer when it is not possible to temporarily open the loop, or use the 35282A signal injection transformer when secondary voltages are up to 600 Vpk.Capture transient events or time histories for complete analysis in any measurement mode (except swept-sine). Use either the entire time-capture record or a selected region of interest for repetitive analysis in the FFT, octave, order track, correlation or histogram instrument modes.Standard 16 Mbytes of memory for deep time-capture capability.Time CaptureAn interval of time-capture data has been selected for analysis in the octave mode.8Taking the measurement is only half the job. Raw measurement data must be stored, recalled, printed,plotted, integrated with other data for analysis, and reported. The 35670A has a variety of tools to help you finish the job.Enhanced Data Transfer Utilities for PCsStandard Data Format (SDF)Utilities, provided with the 35670A,allow you to easily move data from the instrument to wherever it’s needed:Using Measurement ResultsSelf-contained—no ratio synthesizer or tracking filter required Order Maps Order Tracking RPM or Time Trigger Display RPM ProfileTrack Up to Five Orders/Channel Up to 200 Orders Composite Power RPM MeasurementsOrder tracking facilitates evaluation of spectra from rotating machines by displaying vibration data as a function of orders (or harmonics)rather than frequency.All measurement spectra is normalized to the shaft RPM.Now you can have order tracking without compromising portability.Traditional analog order tracking techniques require external tracking filters and ratio synthesizers. With Agilent’s computed order tracking algorithm, external hardware is gone.Because order tracking isimplemented in the software, data is more precise and your job is easier. Compared to traditional analogorder tracking techniques, computed order tracking offers:Computed Order Tracking(Option 1D0)The slice marker feature is used to select and display an order or suborder from an order map.•For general digital signal processingand filtering , translate data files to formats compatible with MATLAB and MATRIX X , Data Set 58, or ASCII for use in popular spreadsheets.•For specific applications, useapplication software that reads SDF files directly, such as STARModal and STARAcoustics from SMS and CADA-PC from LMS.•Transfer data to and from the 35665A, 3566A, 3567A, 3562A,3563A.•Use the viewdata feature to display data on your PC or to convert to the HP-GL format for transfer to Microsoft’s Word for Windows or Lotus’ AMI PRO word processing software.•Convert between HP-LIF and MS-DOS ®formats.•Read data files into a program.Documented ResultsThe 35670A supports a variety of GPIB, serial and parallel printers and plotters for direct hardcopy output.The internal 3.5 inch flexible disk drive stores data, instrument states,HP-GL plots and Agilent Instrument BASIC programs in HP-LIF or MS-DOS formats for future recall or use on HP workstations or a personal computer.Entire display screens can be import-ed directly into your word processing program by plotting HP-GL files to your named DOS file. HP-GL files are interpreted and displayed directly by Microsoft’s Word for Windows and AMI PRO from Lotus Development Corp.•Improved dynamic range athigh orders•More accurate tracking of rapidly changing shaft speeds•Accurate RPM labeled spectra with exact RPM trigger arm •Wide 64:1 ratio of start to stop RPMsOrder MapUse order maps for an overview of vibration data versus RPM or time.Display the amplitude profile of individual orders and suborders using the slice marker function. Alternatively, use trace markers to select individual traces for display.MS-DOS and Microsoft are U.S. registered trademarks of Microsoft Corp.9Order TrackingMeasure only the data you need.Order tracking lets you measure the amplitude profile of up to five orders plus composite power simultaneously on each channel. Up to four orders or three orders and composite power can be dis-played simultaneously.RPM ProfileUse RPM profile to monitor the variation of RPM with time during order tracking measurements.Composite PowerComposite power provides the total signal power in a selected channel as a function of RPM.Run-Up and Run-Down MeasurementsRun-up and run-down measurements of any order are made using external trigger as the phase reference.Display the results as bode or polar plots; both are available.Markers allow convenient notation of important shaft speeds.OrbitsObtain oscilloscope-quality orbit measurements with your 35670A.Unlike traditional FFT analyzers, the 35670A equipped with computed order tracking displays a selected number of loops (usually one) as theshaft RPM is varied.Order tracking is used to simultaneously display up to four orders or a combination of orders,composite power and RPM profile.Markers are used to annotate shaft speeds at selected points in a run-up measurement.Oscilloscope-quality orbit diagrams mean you carry only one instrument onto the shop floor.10Real-Time Third Octave to 40 kHz ANSI S1.11-1986 Filter Shapes Microphone Inputs and Power A-Weighted Overall SPLRPM or Time-Triggered Waterfalls Eliminate the expense and inconvenience of multiple instruments in the field. With optional real-time octave analysis,and the optional microphoneadapter and power supply, you have a complete real-time octave analyzer added to your 35670A at a fraction of the cost of a second instrument.Now you can carry both your FFT and real-time octave analyzers to the job site in the same hand.Real-Time 1/3-Octave to 40 kHz on One ChannelWith two input channels of1/3-octave real-time measurements at frequencies up to 20 kHz, you get all of the information you’ll ever need to understand the noise performance of your product. No misinterpreted measurementsbecause transient components were missed. When the frequency range requirement is 10 kHz or less, use four channels to characterize spatial variations. For those exceptional circumstances, use 1/3-octave resolution at frequencies up to 40 kHz on a single channel.Resolutions of 1/1- and 1/12-octave are also available.Real-Time Octave Measurements (Option 1D1)Microphone Adapter and Power Supply (Option UK4)Overall sound pressure level and A-weighted sound pressure level can be displayed with the octave bands individually, together, or not at all.A fan-off mode lets you use the instrument in the sound field being measured.ANSI S1.11-1986All octave filters comply with filter shape standards ANSI S1.11-1986(Order 3, type 1-D), DIN 45651, and IEC 225-1966. An 80 dB dynamic range for the audio spectrumprovides the performance required by acousticians. Switchable analog A-weighting filters in the input channels comply fully with bothANSI S1.4-1983 and IEC 651-1979 Type 0.Advanced AnalysisUse waterfall displays of octave data for an overview of device noise versus time or RPM.

The result is a 130 dB dynamic range. With FFT-based network analysis, all frequency points are stimulated simultaneously and the instrument configures itself to measure thehighest amplitude response—thereby limiting the dynamic range.Characterize Nonlinear NetworksUse the auto-level feature to hold the input or output amplitude constant during a sweep. This provides the device response for a specific signal amplitude. With FFT-based network analysis using random noise, the randomamplitudes of the stimulus tend to “average out” the non-linearities and therefore does not capture thedependency of the response on the stimulus amplitude.Logarithmic SweepTest devices over more than six decades of frequency range using logarithmic sweep. In this mode,the frequency is automatically adjusted to provide the same resolution over each decade offrequency range. With FFT-network analysis, resolution is constant—not a problem when measuring over narrow frequency ranges.FlexibleMake the measurement your way.Independently select logarithmic or linear sweep, sweep up or down,automatic or manual sweep, and autoresolution.Automatic Frequency ResolutionUse autoresolution to obtain the fastest sweep possible without sacrificing accuracy. With autoresolution, the 35670Aautomatically adjusts the frequency step according to the deviceresponse. High rates of amplitude and phase change are matched with small frequency steps. Low rate-of-change regions are quickly measured with larger frequency steps.Test Multiple Devices SimultaneouslyIncrease throughput in production.Swept-sine measurements up to 25.6 kHz can be made on three devices simultaneously using swept-sine on a four-channel 35670A.

流动分析仪原理
流动分析仪是一种用来分析流动样品中的物质含量的仪器。
它采用了一种叫做流动分析法的分析原理，该原理通过控制和监测流体的流动过程，来实现对样品中目标物质含量的测定。
流动分析法的原理基于化学反应和物质浓度的相关性。
在流动分析仪中，样品通过一个连续的流体系统进行处理。
首先，样品被引入到一个注射器中，然后注射器上方设有一个控制阀门，用于控制样品的进入速度。
样品进入后，会与试剂相遇，并在反应器中发生化学反应。
在反应器中，目标物质与试剂发生反应，生成一个可测量的物理或化学信号。
这个信号可以是电流、光强度、吸光度等。
这个信号随着目标物质浓度的增加而不断变化。
通过监测信号的变化，我们可以得出样品中目标物质的浓度。
流动分析仪中的传感器被用来检测和测量上述信号的变化。
传感器通常会将信号转化为电信号，并通过电子系统进行放大、处理和记录。
通过与标准样品进行对比，我们可以得出最终的测量结果。
流动分析仪的优点是操作简单、灵敏度高、分析速度快，并且可以实现自动化。
它在环境分析、食品安全检测、生物医学研究等领域广泛应用。
需要注意的是，为了确保测量的准确性，流动分析仪的各个部分需要严格控制和校准，以消除误差和提高重复性。
此外，样
品的处理和试剂的选择也会对测量结果产生影响，因此需要进行仔细的优化和验证。
