Datasheet

11.3. Mkr->Start
Set the start frequency of analyzer to be the frequency of current valid marker.
If Normal is selected, the start frequency will be set to the frequency of current marker.
If Delta, Delta Pair, or Span Pair is selected, the start frequency will be set to the frequency
where Delta Marker is.
In Zero span mode, this function is invalid.
11.4. Mkr->Stop
Set the stop frequency of analyzer to be the frequency of current valid marker.
If Normal is selected, the stop frequency will be set to the frequency of current marker.
If Delta, Delta Pair, or Span Pair is selected, the stop frequency will be set to the frequency
where Delta Marker is.
In Zero span mode, this function is invalid.
11.5. Marker Δ->Span
Set the span of analyzer to be the difference between the two markers in type of of Delta, Delta Pair
or Span Pair. In Zero span mode, this function is invalid.
11.6. Mkr->Ref
Set the reference level of analyzer to be the amplitude of current valid marker.
If Normal is selected, the reference level will be set to the amplitude of current marker.
If Delta, Delta Pair, or Span Pair is selected, the reference level will be set to the amplitude
where Delta Marker is.
