14.5.3.3 Defining Weighting Filters
The following commands define weighting filters for ACLR measurements.
[SENSe:]POWer:ACHannel:FILTer:ALPHa:ACHannel........................................................ 848
[SENSe:]POWer:ACHannel:FILTer:ALPHa[:ALL]............................................................... 848
[SENSe:]POWer:ACHannel:FILTer:ALPHa:ALTernate<ch>................................................. 848
[SENSe:]POWer:ACHannel:FILTer:ALPHa:CHANnel<ch>.................................................. 849
[SENSe:]POWer:ACHannel:FILTer[:STATe]:ACHannel....................................................... 849
[SENSe:]POWer:ACHannel:FILTer[:STATe][:ALL].............................................................. 849
[SENSe:]POWer:ACHannel:FILTer[:STATe]:ALTernate<ch>................................................ 850
[SENSe:]POWer:ACHannel:FILTer[:STATe]:CHANnel<ch>................................................. 850
[SENSe:]POWer:ACHannel:FILTer:ALPHa:ACHannel <Alpha>
This command defines the roll-off factor for the adjacent channel weighting filter.
For asymmetrical MSR signals, this command defines the roll-off factor for the lower
adjacent channel. To configure the factor for the upper adjacent channel, use the
[SENSe:]POWer:ACHannel:FILTer:ALPHa:UACHannel command.
Parameters:
<Alpha> Roll-off factor
Range: 0 to 1
*RST: 0.22
Manual operation: See "Weighting Filters" on page 176
See "Weighting Filters" on page 187
[SENSe:]POWer:ACHannel:FILTer:ALPHa[:ALL] <Value>
This command defines the alpha value for the weighting filter for all channels.
Parameters:
<Value> *RST: 0.22
Example:
POW:ACH:FILT:ALPH:ALL 0.35
[SENSe:]POWer:ACHannel:FILTer:ALPHa:ALTernate<ch> <Alpha>
This command defines the roll-off factor for the alternate channel weighting filter.
For asymmetrical MSR signals, this command defines the roll-off factor for the lower
alternate channels. To configure the factor for the upper alterante channels, use the
[SENSe:]POWer:ACHannel:FILTer:ALPHa:UALTernate<ch> command.
