The SR785 Two-Channel Dynamic Signal Analyzer is a
precision, full-featured signal analyzer that offers state-ofthe-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 measurements are simultaneously
acquired and can be displayed without re-taking data.
