Basic Settings
FREQ
Sets the frequency parameters of the analyzer.
Center Freq
Sets the center frequency of the current channel.
Remarks:
When you modify the center frequency, the start and stop frequency will be
modified automatically if the span remains to be unchanged.
Modifying the center frequency indicates that the frequency is changed along
the current channel horizontally, and the adjustable range should be within the
frequency range specified in the technical specifications of the analyzer.
You can use the numeric keys, the knob, or arrow keys to modify this parameter;
you can also use the touch screen to modify the parameter.

Note
[1]
: The maximum measurement frequency Fmax is determined by the instrument model. For
RSA3030E, Fmax is 3 GHz; for RSA3015E, Fmax is 1.5 GHz.
Start Freq
Sets the start frequency of the current frequency channel.
Remarks:
When you modify the start frequency, the center and stop frequency will be
changed if the span remains to be unchanged.
You can use the numeric keys, the knob, or arrow keys to modify this parameter;
you can also use the touch screen to modify the parameter.
