3 IQ Analyzer (Basic) Mode
3.1 Complex Spectrum Measurement
If the selected marker was OFF, then it is turned on as a POSition marker and a
peak search is performed.
Remote Command Complex Spectrum:
:CALCulate:SPECtrum:MARKer[1]|2|…|12:MAXimum:LEFT
Streaming:
:CALCulate:STReaming:MARKer[1]|2|…|12:MAXimum:LEFT
Example
:CALC:SPEC:MARK2:MAX:LEFT
State Saved Not part of saved state
Minimum Peak
Moves the selected marker to the minimum Y-Axis value on the current trace.
Minimum (negative) peak searches do not have to meet the peak search criteria. It
just looks for the lowest y-axis value. If the selected marker is OFF, it is turned on
before the minimum search is performed.
Remote Command Complex Spectrum:
:CALCulate:SPECtrum:MARKer[1]|2|…|12:MINimum
Streaming:
:CALCulate:STReaming:MARKer[1]|2|…|12:MINimum
Example
:CALC:SPEC:MARK:MIN

Pk-Pk Search
Finds and displays the amplitude and frequency (or time, if in zero span) differences
between the highest and lowest y-axis value. Places the selected marker on the
minimum value on its selected trace. Places that marker’s reference marker on the
peak of its selected trace.
This function turns on the reference marker and sets its mode to Normal if it is not
already on. (These markers may be on two different traces.)
The rules for finding the maximum peak are the same as for Peak Search, including
the use of the peak criteria rules. However, the minimum trace value is not required
to meet any criteria other than being the minimum y-axis value in the trace.
If the selected marker is OFF, a DELTa type marker is turned on and the peak-to-
peak search is done. If the selected marker is ON, but it is not a DELTa marker, then it
is changed to DELTa, which turns on the reference marker if needed, and then it
performs the peak-to-peak function.
