The 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 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 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 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
