R&S FSP Remote Control – Description of Commands
SENSe Subsystem
[SENSe<1|2>:]POWer:ACHannel:BANDwidth|BWIDth[:CHANnel] 100 Hz to 1000 MHz
This command sets the channel bandwidth of the radio communication system. The bandwidths of
adjacent channels are not influenced by this modification (in contrast to the FSE family).
With
SENS:POW:HSP ON
the steep-edged channel filters from the table "List of available channel
filters" in chapter “Instrument Functions” , section “Setting the Bandwidths and Sweep Time – BW Key”
on page 4.18 are available.
Example:
"POW:ACH:BWID 30kHz"
'Sets the bandwidth of the TX channel to 30 kHz.
Characteristics: *RST value: 14 kHz
SCPI: device-specific
Mode: A-F
[SENSe<1|2>:]POWer:ACHannel:FILTer:ALPHa:ACHannel 0…1
This command sets the rolloff factor of the RRC weighting filter for the adjacent channel. It is only
available if Fast ACP is not active and no predefine standard is selected.
This command changes the setting for the alternate channels as well.
Example:
"POW:ACH:FILT:ALPH:ACH 0.26"
'sets Alpha to 0.26
Characteristics: *RST value: 0.22
SCPI: device-specific
Mode: A
[SENSe<1|2>:]POWer:ACHannel:FILTer:ALPHa:ALL 0…1
This command sets the rolloff factor of the RRC weighting filter for the TX channel, the adjacent
channel and all alternate channels as well. It is only available if Fast ACP is not active and no
predefined standard is selected. The query command is not supported..
Example:
"POW:ACH:FILT:ALPH:ALL 0.26"
'sets Alpha to 0.26
Characteristics: *RST value: 0.26
SCPI: device-specific
Mode: A
[SENSe<1|2>:]POWer:ACHannel:FILTer:ALPHa:ALTernate<1...11> 0…1
This command sets the rolloff factor of the RRC weighting filter for the alternate channels. It is only
available if Fast ACP is not active and no predefine standard is selected.
This command changes the setting for the adjacent channel as well. The numeric suffixes at ALTernate
are irrelevant for this command.
Example:
"POW:ACH:FILT:ALPH:ALT 0.26"
'sets Alpha to 0.26
Characteristics: *RST value: 0.22
SCPI: device-specific
Mode: A
