Output RF Spectrum Subsystem
MODE
MODE
Description Selects/queries the MODE for Output RF Spectrum measurements.
Syntax ORFSpectrum:MODE?
ORFSpectrum:MODE <string>
Options ’RAMP REF’ | ’RAMPING’ |
’MOD REF’ | ’MODULATN’
Where;
• RAMP REF means make a reference measurement needed to make Output RF
Spectrum due to ramping measurements.
• RAMPING means power is measured for the Output RF Spectrum during the time
when the envelope is ramping up and down. (The peak value is returned within the time
interval 28 us before bit 0 to 28 us after bit 147.)
• MOD REF means make a reference measurement needed to make Output RF Spectrum
due to modulation measurements.
• MODULATN (modulation) means power is measured for the Output RF Spectrum
during the useful bits.
SACalibrate
Description Calibrates the Spectrum Analyzer for making Output RF Spectrum or Pulse On/Off Ratio
measurements. This command is only active when TRIG:MODE[:DSP] = ’SINGLE’.
Syntax ORFSpectrum:SACalibrate
Options Not Applicable.
