Spectrum Emission Mask Measurement
Meas Setup
PSD Sets the power spectral density in the carrier that is used to compute the relative power spectral density values for the offsets when Meas Type is set to PSD Ref. When the state is set to auto, this will be set to the measured carrier power spectral density.For WLAN 802.11ac (80 MHz + 80 MHz), the higher of the power density readouts of the two carriers is used for computing the relative PSD values for the offset.
Remote Command: [:SENSe]:SEMask:CARRier[:POWer] <real>
[:SENSe]:SEMask:CARRier[:POWer]?
[:SENSe]:SEMask:CARRier:AUTO[:STATe] OFF|ON|1|0
[:SENSe]:SEMask:CARRier:AUTO[:STATe]?
Example: SEM:CARR 100dBm
SEM:CARR?
SEM:CARR:AUTO OFF
SEM:CARR:AUTO?
Notes: The min and max values given are for Meas Type = Total Pwr Ref.
You must be in the mode that includes SEM measurement to use this
command. Use :INSTrument:SELect to set the mode..
This BAF SCPI command is available in all the Meas Type case.
Dependencies: This "Total Power Ref" parameter is coupled with the "Meas Type" parameter.
The softkey would be active if the Meas Type is set to Total Power Ref.
Otherwise, it is grayed out.
Preset: Measured carrier reference power
State Saved: Saved in instrument state.
Min: –200 dBm
Max: 200 dBm
