Functions and Measurements
Spectrum Monitor
Spectrum Monitor
The scrolling three- dimensional display is noted for its
ability to track the frequency and power behavior over the
time, particularly intermittent signals. Spectrum Monitor may
be used to analyze the stability of a signal over the time, or
to identify intermittent interference signals in
communications systems.
The X- axis represents frequency, and amplitude is
represented by color; red for a strong signal and blue for
noise floor. The Y- axis represents time, with the trace from
the newest sweep displayed at the bottom of the screen.
Earlier traces move up toward the top with each new sweep.
Two coupled markers allow the user to place a marker on
any trace in the Spectrum Monitor and view the normal
spectrum for the time of that sweep. The time interval
between sweeps can be adjusted, and up to 1500 traces can
be displayed and saved.
