Peak Search 18
Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz 439
Peak Search
Sets the mode for Peak Search to either Max or Param and applies to Peak Search only.
• Max (Maximum mode) places a marker on the highest peak whenever a Peak Search is
performed.
• Param (Parameter mode) searches only for peaks that meet the values set with Peak
Excursn and Pk Threshold.
Key Path: Peak Search, Search Param
State Saved: Saved in Instrument State.
Factory Preset: Maximum
Remote Command:
:CALCulate:MARKer:PEAK[1]|2|3|4:SEARch:MODE
PARameter|MAXimum
:CALCulate:MARKer:PEAK[1]|2|3|4:SEARch:MODE?
Remote Command Notes:
If mode is set to MAXimum (Max), peak search will place the marker at the maximum
amplitude in the trace. If mode is set to PARameter (Param), peak search will place the
marker at the highest peak that rises and falls by at least the peak excursion above the peak
threshold. If no peak meets the excursion and threshold criteria, a No Peak Found error
(error 202) is issued.
The following commands are not affected by the setting of CALC:MARK:PEAK SEAR:MODE.
They will always use the parameter search mode that defines peaks based on peak
excursion and peak threshold.
:CALCulate:MARKer[1]|2|3|4:MAXimum
:CALCulate:MARKer[1]|2|3|4:MAXimum:LEFT
:CALCulate:MARKer[1]|2|3|4:MAXimum:NEXT
:CALCulate:MARKer[1]|2|3|4:MAXimum:RIGHt
:CALCulate:MARKer:PEAK:TABLe:STATe OFF|ON|0|1
Example:
CALC:MARK:PEAK:SEARC:MODE PAR sets the parameter search mode.
CALC:MARK:PEAK:THR –60 dBm sets the threshold to –60 dBm.
CALC:MARK:PEAK:EXC 30 dB sets the minimum peak excursion requirement to 30
dB.
