Spectrum Emission Mask Measurement
Meas Setup
Power Ref
Sets the power reference in the carrier that will be used to compute the relative values for the offsets.
Total Power
Sets the power in the carrier (ref channel) that is used to compute the relative power values for the
offsets. When the state is set to auto, this value is set to the measured carrier reference power. When set
to manual, the result takes on the last measured value, or can be manually entered.
For WLAN 802.11ac (80 MHz + 80 MHz), the higher of the power readouts of the two carriers is used
for computing the relative power values for the offset.
Notes: Bandwidth sub op code, 1 is for BTS, 2 for MS. Default is BTS.
You must be in the mode that includes SEM measurement to use this
command. Use :INSTrument:SELect to set the mode.
Couplings: When Res BW is set manually, Mode coupling is set to MANual
When set to Auto, the VBW/RBW Ratio is automatically calculated.
