6.16.11 SENSe:POWer Subsystem
This subsystem controls the setting of the instrument's channel and adjacent channel power measure-
ments.
The measurement windows are selected by SENSe1 (screen A) and SENSe2 (screen B).
[SENSe<1|2>:]POWer:ACHannel:SPACing:CHANnel<1 to 11> 100 Hz to 2000 MHz
This command defines the channel spacing of the carriers. At the same time the spacing of carriers
with higher channel number are set to the same value. If the spacing is equal between all carriers it is
sufficient to set the spacing between carrier 1 and 2 with the command SENS:POW:ACP:SPAC:CHAN1
or SENS:POW:ACP:SPAC:CHAN. If the spacing are set in ascending order individual spacing of the
carriers can be set.
The command is available only for measurements in the frequency domain (span > 0).
Example:
"POW:ACH:SPAC:CHAN 25kHz"
'Sets the spacing between all carriers to 25 kHz
"POW:ACH:SPAC:CHAN2 4.8MHz"
'sets the spacing between TX carrier 2 and 3 to 4.8 MHz.
Characteristics: *RST value: 20 kHz
SCPI: device-specific
Mode: A-F
[SENSe<1|2>:]POWer:ACHannel:SPACing:ACHannel 100 Hz to 2000 MHz
This command defines the channel spacing of the adjacent channel to the TX channel. At the same
time, the spacing of alternate adjacent channels 1 to 11 is set to the double or triple etc. of the entered
value.
The command is only available in the frequency domain (span > 0).
Example:
"POW:ACH:SPAC:ACH 33kHz"
'Sets the spacing between the carrier signal and
'- the adjacent channel to 33 kHz
'- the alternate adjacent channel 1 to 66 kHz
'- the alternate adjacent channel 2 to 99 kHz
Characteristics: *RST value: 14 kHz
SCPI: device-specific
Mode: A-F
[SENSe<1|2>:]POWer:ACHannel:SPACing:ALTernate<1 to 11> 100 Hz to 2000 MHz
This command defines the spacing between the alternate adjacent channels and the TX channel. If
the spacing to an alternate adjacent channel ALTernate<k> is modified, the spacing to all the following
alternate adjacent channels ALTernate<n> is set to (<n> + 1) / (<k> + 1) times the entered value.
This command is only available in the frequency domain (span > 0).
Example:
"POW:ACH:SPAC:ALT1 100kHz"
'Sets the spacing between TX channel and alternate adjacent channel 1 to 100 kHz
and between TX channel and alternate adjacent channel 2 to 150 kHz.
