Keysight E6680A - Query the Signal Peaks (Remote Query Only)

3 IQ Analyzer (Basic) Mode
3.1 Complex Spectrum Measurement
The Peak Search type simply finds the highest point on the trace, subject to the
peak-search qualifications.
However, using Peak Search Mode, you can change the Peak Search type so that it
also uses the Excursion and Threshold criteria. This allows you to find the Maximum
point on the trace that also obeys the Excursion and/or Threshold criteria. This
would be useful if, for example, you did not want to perform the peak search at all
unless there was a signal on the screen above a certain level.
Option SCPI Behavior
Highest Peak
MAXimum
Pressing Peak Search simply finds the highest peak on the
marker’s trace
Use Excursion &
Threshold
PARameter
The search is also qualified by the Excursion and Threshold
values (as long as these criteria are ON)
Note that this control also affects "Continuous Peak Search" on page 212 and the
Peak Search half of "Pk-Pk Search" on page 211.

Complex Spectrum:
:CALCulate:SPECtrum:MARKer:PEAK:SEARch:MODE MAXimum | PARameter
:CALCulate:SPECtrum:MARKer:PEAK:SEARch:MODE?
Streaming:
:CALCulate:STReaming:MARKer:PEAK:SEARch:MODE MAXimum | PARameter
:CALCulate:STReaming:MARKer:PEAK:SEARch:MODE?
Example
:CALC:SPEC:MARK:PEAK:SEAR:MODE MAX
Sets Highest Peak mode
:CALC:SPEC:MARK:PEAK:SEAR:MODE PAR
Sets Excursion & Threshold mode
:CALC:SPEC:MARK:PEAK:SEAR:MODE PAR
For Complex Spectrum, this sets Same as Next Pk mode

MAXimum
State Saved Saved in instrument state
Range Highest Peak | Use Excursion & Threshold
Query the Signal Peaks (Remote Query Only)
Provided for backwards compatibility with ESA and PSA. For new designs, use
:CALC:DATA:PEAK instead.
Returns the signal peaks by frequency or by amplitude. This query uses only Trace 1
data. The sort mode is determined by :TRACe:MATH:PEAK:SORT.
:CALCulate:MARKer:PEAK:EXCursion and
:CALCulate:MARKer:PEAK:THReshold are used to determine what is a signal
