438 Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz
18 Peak Search
Example:
:CALC:MARK:PEAK:EXC 30 DB sets the minimum peak excursion requirement to
30 dB.
See the full example for the CALC:MARK:PEAK:SEAR:MODE command below.
Pk Threshold
Specifies the minimum signal level for the N8201A internal peak identification routine to
recognize as a peak. To be considered a peak, a signal must rise above the Peak Threshold
value by at least the value specified in Peak Excursn, then fall back down by at least the
Peak Excursn. This applies to all traces and all windows. Press ESC or select another active
function to hide the threshold line. Applies to Next Peak, Next Peak Left, and Next Peak
Right. If Peak Search is set to Param, it also applies to Peak Search.
Key Path: Peak Search, Search Param
Dependencies/Couplings: This function is not available when Y-Axis is set to
Frequency instead of Amplitude.
State Saved: Saved in Instrument State.
Factory Preset: –90 dBm
Te rm in a tor s: dBmV, dBμV, dBμΑ, V, W, A
Default Terminator: dBm
Resolution/Rounding/Truncation: .001 dBm
Range: From the current reference level to the bottom of the display range
Remote Command:
:CALCulate:MARKer[1]|2|3|4:PEAK:THReshold <ampl>
:CALCulate:MARKer[1]|2|3|4:PEAK:THReshold?
Remote Command Notes:
CALC:MARK:PEAK:SEAR:MODE must be set to PARameter if you want peak search
to take advantage of the threshold excursion.
Example:
:CALC:MARK:PEAK:THR -60 dBm sets the threshold to -60 dBm.
See the full example for the CALC:MARK:PEAK:SEAR:MODE command below.
