FREQ 
Sets 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/Stop Frequency (
start
f
/
stop
f
); or Center 
Frequency/Span (
center
f
/
span
f
). If any of the four parameters is changed, the other 
three parameters will make adjustment automatically to ensure the coupling 
relationship among them:
