Averaging
Various averaging modes let youfurther refine spectrum analysismeasurements. Time averagingextracts repetitive signals out of thenoise while rms averaging reducesthe noise to its mean value. Exponen-tial averaging, available for both timeand rms averaging, is useful forreducing the noise while followingchanging signals—tracking theresonance shifts in a fatiguingstructure for example.
FFT-based spectrum analyzers, suchas the HP 35670A, are ideal formeasuring the spectra of low-frequency signals like speech ormechanical vibration. Transientcomponents, usually missed withswept-frequency analyzers, are easilymeasured and displayed at speedsfast enough to follow trends. TheHP 35670A has both the performanceand features required to take fulladvantage of this technology.
16-Bits for High Performance
With a 16-bit ADC (90 dB typicaldynamic range) and a real-timebandwidth of 25.6 kHz, you can besure nothing will be missed. Resolvesignals using 100 to 1600 linesresolution, or for really close-inanalysis, use frequency zoom toresolve signals with up to 61 µHzresolution. Use time or RPM armingto develop waterfalls of sequentialvibration spectra for trend analysis orfor an overview of device vibration.
Power and Linear Spectrums
Match your spectrum measurementmode to the signal being tested. Uselinear spectrum analysis to measureboth the amplitude and phase ofperiodic signals such as the spectra ofrotating machinery. Power spectrumanalysis is provided for averagingnonrepetitive signals.

Time Domain
Use your spectrum analyzer as a low-frequency oscilloscope or viewsignals in the time and frequencydomains simultaneously. (Note: anti-alias filters can be switched off.)Special markers for time-domain datafacilitate extraction of key controlsystem performance parameters:overshoot, rise time, setting time, anddelay time.
Data Table
Use a tabular format to keep trackof key frequencies in the spectra ofrotating machinery. The amplitudeand frequency of the signal and a16-character entry label field arelisted for each selected point.
Markers
Markers streamline analysis byhelping you select and display specificdata. Marker functions include markerto peak, next right peak, and coupledmarkers for selecting points inmultiple data displays. Markersreadouts are absolute or relative toyour selected reference.
Special Markers
Three special marker functionsfacilitate analysis of your spectraldata. Sideband markers aid analysisof modulation signals. Use thisfunction to quickly locate sidebandsin the complicated spectra of rotatingmachines. A band-power marker readsthe total power in a selected band offrequencies and a total harmonicdistortion marker lets you calculatetotal harmonic distortion withoutincluding the effects of noise.

Automatic Units Conversion
Display vibration data in the unitsof your choice. Select g, m/sec2,
in/sec2, m/s, in/s, m, mil, inch,
Kg, lb, N, dyn, or pascals as appropri-ate for your application. The instru-ment automatically converts fre-quency-domain data from specifiedinput transducer units to the unitsyou select for display. For example,accelerometer data is automaticallyconverted and displayed as mils whenmils are selected. Of course, dB, dBV,
dBm and volts are available forelectrical applications.

The HP 35670A has the flexibilityto make measurements of bothelectrical networks and mechanicaldevices. FFT-based network analysisis fast enough to allow real-timeadjustments of circuit parameterswhile the swept-sine option providesexacting measurements over morethan six frequency decades, and a130 dB dynamic range.
Source
Select the optimum stimulus for eachapplication—random noise, periodicchirp, pink noise, fixed sine, burstrandom, and burst chirp. For zoomednetwork analysis measurements, thesource is band-translated to matchthe zoom span at frequencies up to51.2 kHz. An optional arbitrary sourcelets you test your product using real-world signals. A ±10 volt dc sourceoffset facilitates tests of controlsystems.
Impact Testing
Force and exponential windowsallow impact testing for modal andstructural analysis. Quality measure-ments are ensured using preview andaccept/reject during averaging. A4 mA constant current transducerpower supply is built-in for trueportability.
Limits
Test network measurements againstpreset limits. Up to 800 separate linesegments are available for settingupper and lower limits. Limits arealso used for testing spectrummeasurements.
Four Channels (option AY6)
Test up to three devices simulta-neously with a four-channelHP 35670A. Channel one is thecommon reference channel andtwo, three, and four are the responsechannels. Alternatively, selectchannels one and three as referencechannels for two totally independentnetwork measurements. Seeoption AY6 description for moreinformation.
Limits are used
for go/no go
testing in
production. The
response of an
accelerometer is

RPM Measurements
Order tracking facilitates evaluationof spectra from rotating machines bydisplaying vibration data as a functionof orders (or harmonics) rather thanfrequency. All measurement spectrais normalized to the shaft RPM.
Now you can have order trackingwithout compromising portability.Traditional analog order tracking
techniques require external trackingfilters and ratio synthesizers. WithHP’s computed order trackingalgorithm, external hardware is gone.
Because order tracking is imple-mented in the software, data is moreprecise and your job is easier.Compared to traditional analog ordertracking techniques, computed ordertracking offers:
• Improved dynamic range athigh orders
•More accurate tracking of rapidlychanging shaft speeds
•Accurate RPM labeled spectrawith exact RPM trigger arm
•Wide 64:1 ratio of start to stop RPMs
Order Map
Use order maps for an overview ofvibration data versus RPM or time.Display the amplitude profile ofindividual orders and suborders usingthe slice marker function. Alterna-tively, use trace markers to selectindividual traces for display.
Taking the measurement is onlyhalf the job. Raw measurement datamust be stored, recalled, printed,plotted, integrated with other datafor analysis, and reported. TheHP 35670A has a variety of tools tohelp you finish the job.
Enhanced Data Transfer
Utilities for PCs
Standard Data Format (SDF) Utili-ties, provided with the HP 35670A,allow you to easily move data from theinstrument to wherever it’s needed:
• For general digital signal processingand filtering , translate data files toformats compatible with MATLABand MATRIXX, Data Set 58, or ASCIIfor use in popular spreadsheets.
• For specific applications, useapplication software that reads SDFfiles directly, such as STARModaland STARAcoustics from SMS andCADA-PC from LMS.
• Transfer data to and from theHP 35665A, 3566A, 3567A, 3562A,3563A.
• Use the viewdata feature to displaydata on your PC or to convert to theHP-GL format for transfer to Micro-soft’s Word for Windows or Lotus’AMI PRO word processing software.
• Convert between HP-LIF andMS-DOS formats.
• Read data files into a program.
Documented Results
The HP 35670A supports a variety ofHP-IB, serial and parallel printers andplotters for direct hardcopy output.The internal 3.5 inch flexible diskdrive stores data, instrument states,HP-GL plots and HP InstrumentBASIC programs in HP-LIF or MS-DOSformats for future recall or use on HPworkstations or a personal computer.
Entire display screens can beimported directly into your wordprocessing program by plottingHP-GL files to your named DOS file.HP-GL files are interpreted anddisplayed directly by Microsoft’sWord for Windows and AMI PROfrom Lotus Development Corp.

Characterize Nonlinear
Networks
Use the auto-level feature to hold theinput or output amplitude constantduring a sweep. This provides thedevice response for a specific signalamplitude. With FFT-based networkanalysis using random noise, therandom amplitudes of the stimulustend to “average out” the non-linearities and therefore does notcapture the dependency of theresponse on the stimulus amplitude.
Logarithmic Sweep
Test devices over more than sixdecades of frequency range usinglogarithmic sweep. In this mode, thefrequency is automatically adjusted toprovide the same resolution overeach decade of frequency range. WithFFT-network analysis, resolution isconstant—not a problem whenmeasuring over narrow frequencyranges.
Flexible
Make the measurement your way.Independently select logarithmic orlinear sweep, sweep up or down,automatic or manual sweep, andautoresolution.

Resolution
Use autoresolution to obtain thefastest sweep possible withoutsacrificing accuracy. Withautoresolution, the HP 35670Aautomatically adjusts the frequencystep according to the device re-sponse. High rates of amplitude andphase change are matched with smallfrequency steps. Low rate-of-changeregions are quickly measured withlarger frequency steps.
Test Multiple Devices
Simultaneously
Increase throughput in production.Swept-sine measurements up to25.6 kHz can be made on threedevices simultaneously using swept-sine on a four-channel HP 35670A.Channel one is the common referencechannel for these measurements.
Alternatively, channels one andthree can be designated as indepen-dent reference channels for twototally independent swept-sinemeasurements.
While FFT-based network analysis isfast and accurate, swept-sinemeasurements are a better choicewhen the device under test has awide dynamic range or covers severaldecades of frequency range. Useswept-sine measurements to extendthe network measurement capabili-ties of the HP 35670A.
Network Analysis Over a
130-dB Range
With traditional swept-sine, theHP 35670A is optimally configured tomeasure each individual point in thefrequency response. The result is a130 dB dynamic range. With FFT-based network analysis, all frequencypoints are stimulated simultaneouslyand the instrument configures itselfto measure the highest amplituderesponse—thereby limiting thedynamic range.
