8 Channel Power Measurement
Meas Setup
Method
Turns the Root Raised Cosine (RRC) filter On or Off. The
α
value (roll off) for the filter is set to the value of
the Filter Alpha parameter, and the RRC filter bandwidth is set to the Filter BW parameter.
Key Path
Meas Setup
Mode
SA, WCDMA,WIMAX OFDMA, DVB-T/H, DTMB (CTTB), ISDB-T, CMMB, LTE, LTETDD, Digital Cable
TV, WLAN, LTEAFDD, LTEATDD
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. You must be in the
Spectrum Analysis mode, DVB-T/H mode, DTMB (CTTB) mode, ISDB-T mode, CMMB mode, LTE
mode, LTE TDD mode, WLAN mode,WIMAX OFMDA mode or W-CDMA mode to use this command.
Use :INSTrument:SELect to set the mode.
Dependencies
For CDMA2K mode, this key is blank.
For 1xEVDO mode, this key is blank.
For MSR mode, this key is blank.
For LTE-Advanced FDD/TDD mode, this key is blank.
In order to keep backwards compitible with the legacy LTE FDD/TDD, the scpi command is
supported in LTE & LTE-A converged application
For WLAN 802.11 ac (80 + 80 MHz ), RRC Weighted is not supported .
Preset
OFF
State Saved
Saved in instrument state.

Filter Alpha
Inputs the alpha value for the Root Raised Cosine (RRC) filter.
