Remote Control – Description of Commands
CALCulate<1|2>:ADEMod:THD:FREQuency:FUNDamental:AUTO[:STATe]
ON | OFF
This command switches between automatic or manual selection of the fundamental frequency used
for the SINAD and THD calculations. With automatic selection the peak in the AF spectrum is used
as the fundamental frequency.
When switching the auto state off, the current modulation frequency result is used as a default for
CALC:ADEM:THD:FREQ if the measurement result is available at this time.
This command is available, if Result
AF SPECTRUM
is switched on.
Example:
"CALC:ADEM:THD:FREQ:FUND:AUTO OFF"
' deactivates the auto se
' lection and uses the
' current Modulation Freq.
' as fundamental frequency.
"CALC:ADEM:THD:FREQ:FUND:VAL 1kHz"
'
set the fundamental
' frequency.

*RST-Wert:
ON

CALCulate<1|2>:ADEMod:THD:FREQuency:FUNDamental:VALue
ON | OFF
This command sets the fundamental frequency used for the SINAD and THD calculations.
The query command is available only with "CALC:ADEM:THD:FREQ:FUND:AUTO OFF".
Example:
"CALC:ADEM:THD:FREQ:FUND:AUTO OFF"
' deactivates the auto se
' lection and uses the
' current Modulation Freq.
' as fundamental frequency.
Characteristics:
*RST-Wert:
ON
SCPI:
device-specific
The numeric suffix <1 to 4> at marker is irrelevant with this command.
:SENSe<1|2>:FILTer:AWeighted[:STATe]
ON | OFF
This command activates/deactivates the A weighted filter. The weighting filter is active in the
following demodulation bandwidth range:
100 kHz
b
demodulation bandwidth
b
800 kHz
Example:
":SENS:FILT:AW ON"
’ activates the A weighted filter
Characteristics:
*RST-Wert:
OFF
SCPI:
device-specific
The numeric suffix <1|2> is irrelevant with this command.
:SENSe<1|2>:FILTer:CCIR[:UNWeighted][:STATe]
ON | OFF
This command activates/deactivates the CCIR unweighted filter which is the combination of the
20 Hz highpass and 23 kHz low pass filter. The filter is active in the following demodulation
bandwidth range:
50 kHz
b
demodulation bandwidth
b
1.6 MHz
Example:
"SENS:FILT:CCIR ON"
’ activates the unweighted CCIR filter
Characteristics:
*RST-Wert:
OFF
SCPI:
device-specific
The numeric suffix <1|2> is irrelevant with this command.
