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
