Datasheet

The Stanford Research Systems SR785 Two-Channel Dynamic Signal Analyzer is a precision, full-featured signal analyzer that offers state-of-the-art performance at a price that's less than half that of competitive analyzers. Building on its predecessor, the SR780, the SR785 incorporates new firmware and hardware that make it the ideal instrument for analyzing both mechanical and electrical systems. For measurements involving servo systems, control systems, acoustics, vibration testing, modal analysis, or machinery diagnostics, the Stanford Research Systems SR785 has the features and specifications to get the job done.
 

Standard measurement groups include FFT, order tracking, octave, swept-sine, correlation, time capture, and time/histogram. The Stanford Research Systems SR785 brings the power of several instruments to your application: a spectrum analyzer, network analyzer, vibration analyzer, octave analyzer and oscilloscope.
 

A unique measurement architecture allows the Stanford Research Systems SR785 to function as a typical dual-channel analyzer with measurements like cross spectrum, frequency response, coherence, etc. Alternatively, the instrument can be configured so that each input channel functions as a single-channel analyzer with its own span, center frequency, resolution and averaging. This allows you to view a wide-band spectrum and simultaneously zoom in on spectral details. The same advanced architecture provides storage of all measurement building blocks and averaging modes. Vector averaged, rms averaged, unaveraged, and peak hold versions of all measurements are simultaneously acquired and can be displayed without re-taking data.

Features:

  • DC to 102.4 kHz bandwidth
  • 90 dB dynamic range
  • 145 dB dynamic range in swept-sine mode
  • Order tracking
  • 20-pole/20-zero curve fitting
  • Real-time octave analysis
  • Up to 32 Mbyte memory
  • GPIB and RS-232 interfaces
