Carrier Power Measurement Bandwidth and Filter

Carrier powers are measured in some common swept measurements, i.e. CHP,
ACP and SEM. These measurements have parameters for measurement
bandwidth and RRC filter in all or most of the other modes. In the MSR these
parameters are not supported and carrier powers are measured with the
predefined bandwidths and filter states because they depend on the radio
format and because the MSR is designed to have the simpler UI. If it is required
to support them in the future release, they would be parameters of format
parameter set. Here are tables that show predefined measurement bandwidths
and filter states.

Offset/Limit Presets

Immediate action keys/commands are provided for Offset/Limit Presets. When
one of these keys is pressed or a corresponding SCPI command is sent,
Offset/Limit parameters of corresponding measurements are set to predefined
values depending on the carrier configuration and mode setup parameters.
There are two types of this preset command, meas global and local. Apply to
Meas Offset/Limits on Carrier Setup menu is the meas global one. Pressing it
would have ACP, SEM and SPUR recall mask files to set their offset or range
parameters. The meas local keys exist on their Meas Setup menu. They preset
only their local offset/limit parameters when the key is pressed. This preset is
done by recalling mask files provided with XA FW which can be found under
My Document/MSR folder. ACP, SEM and SPUR support Offset/Limit Preset.
Parameters affect the limit preset is listed below.
