Spectrum Emission Mask Measurement
Meas Setup
Spectrum Peak
Sets the spectrum peak power in the carrier that is used to compute the relative power spectral density
values for the offsets when Meas Type is set to Spectrum Peak. When the state is set to auto, this is set to
the measured carrier spectrum peak power. When set to manual, the result takes on the last measured
value, or can be manually entered
Notes: Although the default value is defined, the value is recalculated by the
measurement result just after completing the measurement.
Carrier sub op code. 1 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.
Dependencies: See Couplings
Couplings: This "PSD" parameter is coupled with the "Meas Type" parameter. The key
will be active if the Meas Type is set to PSD. Otherwise, it is grayed out.
Preset: Measured carrier PSD reference power
State Saved: Saved in instrument state.

parameter. This softkey would be active if the "Meas Type" is set to
"Spectrum Peak Ref". Otherwise, grayout.
