SR785 T wo Channel Dynamic Signal Analyzer FFT Spectrum Analysis The SR785 Two Channel Dynamic Signal Analyzer is a precision, full-featured signal analyzer that offers state-of-the-art performance and a wide selection of features at a price that's less than half that of competitive analyzers.
View order maps or track individual orders with the SR785. Run-up and run-down measurements in both polar and bode formats are available. time record, 1000 averages take exactly 4 seconds, during which the SR785 still operates at its maximum display rate.
provided to monitor variations of RPM as a function of time. And a complete selection of time and RPM triggering modes is included allowing you to make virtually any rotating machinery measurement. Swept-Sine Measurements Network analysis using FFT mode produces fast results but suffers from limited dynamic range and frequency resolution.
Top display shows the burst noise source. Bottom display shows an arbitrary waveform downloaded to the SR785 via the IEEE-488 interface. Top display shows a histogram of time data.
Two 2k deep waterfall buffers ensure you’ll never miss important waterfall data. The SR785 doesn’t limit you to a few preselected measurements. With user math you can create an infinite variety of measurements. Wa t e r f a l l Waterfall plots are a convenient way of viewing a time history of your data.
Output The SR785's built-in 3.5" 1.44 MB disk drive, GPIB and RS-232 computer interfaces and Centronics printer port combine to allow almost unlimited flexibility in saving, printing, plotting or exporting your measurement data.
The SRS DataViewer Windows utility enables you to view SR785 data files graphically and save them in different formats. DataViewer The SRS DataViewer is a Windows 95 program that allows you to quickly upload SR785 files into a graphical environment, perform simple editing and cut and paste into other applications.
