3 Short-Range Comms & IoT Mode
3.5 Channel Power Measurement
3.5.8.2 Meas Method
Allows you to choose between Integration Bandwidth and RRC Weighted methods
of making the measurement, and to set certain other relevant parameters.
In MSR, LTE-A FDD/TDD and 5G NR Modes, this feature is not supported.
Meas Method
Selects either the Integration BW (OFF) or RRC Weighted (ON) methods. Selecting
the RRC Weighted method turns the Root Raised Cosine (RRC) filter on. The a value
(roll off) for the filter is set to the value of "RRC Filter Alpha" on page 632, and the
RRC filter bandwidth is set to "RRC Filter BW" on page 633.
Remote Command
[:SENSe]:CHPower:FILTer[:RRC][:STATe] OFF | ON | 0 | 1
[:SENSe]:CHPower:FILTer[:RRC][:STATe]?
Example
:CHP:FILT OFF
:CHP:FILT?
Notes This parameter is normally used when TETRA is selected as the Radio Std
Dependencies For WLAN 802.11 ac (80 + 80 MHz ), RRC Weighted is not supported
Preset

Range Integration BW | RRC Weighted
RRC Filter Alpha
Inputs the alpha value for the Root Raised Cosine (RRC) filter.
Remote Command
[:SENSe]:CHPower:FILTer[:RRC]:ALPHa <real>
[:SENSe]:CHPower:FILTer[:RRC]:ALPHa?
Example
:CHP:FILT:ALPH 0.5
:CHP:FILT:ALPH?
Notes This parameter is normally used when TETRA is selected as the Radio Std
Preset 0.22
