parameters (such as center frequency, reference level).
These menus are related with that whether spectrum
analyzer's frequency, span and frequency marker are in
normal mode or difference frequency marker mode.
3.3.9.16 [Frequency marker center frequency]
Set center frequency equal to frequency marker's frequency.
This function is able to quickly move signal in the center
of screen.
Notes:
If "normal" marker is selected, center frequency is set as
frequency at marker.
If "frequency marker difference" marker is selected,
center frequency is set as frequency at difference marker.
This function is invalid in zero span mode.
3.3.9.17 [Frequency marker
Set spectrum analyzer's center frequency stepping
according to frequency at current marker.
Notes:
If "normal" marker is selected, center frequency
stepping is set as frequency at marker.
If "frequency marker difference" marker is selected,
center frequency stepping is set as frequency at
difference marker.
This function is invalid in zero span mode.
3.3.9.18 [Frequency marker start frequency]
Set spectrum analyzer's start frequency according to
frequency at current marker.
Notes:
If "normal" marker is selected, start frequency is set as
frequency at marker.
If "frequency marker difference" marker is selected, start
frequency is set as frequency at difference marker.
This function is invalid in zero span mode.
frequency stepping] 3.3.9.19 [Frequency marker stop frequency]
Set spectrum analyzer's stop frequency according to
frequency at current marker.
If "normal" marker is selected, stop frequency is set as
frequency at marker.
If "frequency marker difference" marker is selected, stop
frequency is set as frequency at difference marker.
