Freq Offset
You can set a frequency offset value to account for frequency conversions between
the device under test (DUT) and the input terminal of the spectrum analyzer.
Remarks:
The change of this parameter only changes the display values of the center
frequency, start frequency, and stop frequency; but does not affect any
hardware settings of the spectrum analyzer.
You can use the numeric keys, the knob, and the arrow keys on the front panel
to modify this parameter; also you can modify it on the touchscreen. For details,
refer to descriptions in "Parameter Setting".
To eliminate the frequency offset, you can set the frequency offset to 0 Hz.

CF Step
Changes the step size for the center frequency. Changing the center frequency by a
constant step-size value switches the channel to be measured continuously.
Remarks:
Set a proper CF step value, and then select the center frequency. Use the
