FREQ
Set the frequency parameters of the analyzer. The analyzer sweeps within a
specified frequency range and restarts sweeping every time the frequency
parameters are modified.
The frequency range of a channel can be expressed by either of two groups of
parameters: Start Frequency and Stop Frequency (
start
f
/
stop
f
); or Center
Frequency and Span (
center
f
/
span
f
). If any of the parameters is changed, the
others would be adjusted automatically in order to ensure the coupling relationship
among them:
