Setting basic spectrum RF measurement parameters
INIT;*WAI
//Performs a measurement and waits for it to end
CALC:MARK1:FUNC:NOIS:RES?
//Queries the measured noise level (per Hz bandwidth)
Example: measuring phase noise
This example demonstrates how to measure phase noise using markers in a basic
spectrum measurement in a remote environment. It assumes that the basic frequency
sweep described in
"Basic frequency sweep measurement for marker function exam-
ples"
on page 892 has been performed and thus does not begin by presetting the
instrument.
//------------- Configuring the phase noise marker -------------------
DET SAMP
//Switches to Sample detector
CALC:MARK1 ON
//Activates marker1 and sets it to the maximum power level
CALC:DELT:FUNC:PNO ON
//Activates phase noise marker function
CALC:DELT1 ON
CALC:DELT1:X 100kHz
CALC:DELT2 ON
CALC:DELT2:X 500kHz
CALC:DELT3 ON
CALC:DELT3:X 1MHz
CALC:DELT4 ON
CALC:DELT4:X 1.5MHz
//Activates the phase noise measurement function for offsets 100kHz/500kHz/1MHz/1.5MHz.
BAND:VID?
//Queries the used VBW (= 0.1*RBW)
//-------- Querying the phase noise results ------------------------------
