[SENSe:]ADEMod:DETector PPEak | MPEak | PAVerage | RMS | AVERage | SRMS | THD | SINad
[[,PPEak | MPEak | PAVerage | RMS | AVERage | SRMS | THD | SINad],…]
This command switches on the detectors whose results are to be displayed in the modulation
summary.
PPEak
Result of measurement with +PK detector
MPEak Result of measurement with -PK detector
PAVerage Result of averaging
±
PK/2, i.e. (plus peak + minus peak)/2
AVERage Result of measurement with average detector
RMS Result of measurement with RMS detector
SRMS Result of measurement with \ 2 RMS detector
THD Total harmonic distortion
SINad Signal, noise and distortion
THD and SINad are always displayed together. The above command can be used to
activate any combination of detectors. For the detailed configuration of the individual
detectors, including relative measurements, see the commands below.
Example:
"ADEM:DET PPE, RMS, THD"
'The peak and RMS detectors are switched on
together with the THD and the SINAD display.
Characteristics: *RST value: PPE
SCPI: device-specific
[SENSe:]ADEMod:DETector:AVERage:MODE ABSolute | RELative
This command switches on absolute or relative measurement for the average detector in the
modulation summary. Each time the relative measurement mode is switched on, the current
measured value is taken as a reference for the subsequent relative measurements. The command is
executed independently of the settings for the other detectors.
Example: "
ADEM:DET:AVER:MODE REL
" 'Switches on the relative measurement
'for the average detector.
Characteristics: *RST value: ABS
SCPI: device-specific
[SENSe:]ADEMod:DETector:AVERage:REFerence <numeric_value>
This command sets or queries the reference value for the relative measurement for the average
detector in the modulation summary.
Example: "
ADEM ON
" 'Switches on the demodulator.
"
CALC2:FEED 'XTIM:FM:TDOM'
" 'Switches on the FM modulation summary.
"
ADEM:DET:AVER ON
" 'Switches on the average detector.
"
ADEM:DET:AVER:MODE REL
" 'Switches on the relative measurement
for the average detector.
"
ADEM:DET:AVER:REF 20 kHz
" 'Sets the reference value.
Characteristics: *RST value: 0
SCPI: device-specific
[SENSe:]ADEMod:DETector:AVERage:REFerence:AUTO ONCE
This command uses the current measured value as a reference for the relative measurement for the
average detector in the modulation summary.
Example: "
ADEM:DET:AVER:REF:AUTO ONCE
" 'Uses the current measured value
'as a reference for the relative
'measurement.
Characteristics: *RST value -
SCPI: device-specific
