[SENSe:]POWer:ACHannel:SPACing:ALTernate<channel>
POW:ACH:SPAC:ALT2 140 KHZ
Sets the spacing between the transmission channel and alternate channel 2 to 140
kHz.
POW:ACH:MODE ABS
Switches on absolute power measurement.
CALC:MARK:FUNC:POW:SEL ACP
Switches on the adjacent-channel power measurement.
INIT:CONT OFF
Switches over to single sweep mode.
INIT;*WAI
Starts a sweep and waits for the end of the sweep.
CALC:MARK:FUNC:POW:RES? ACP
Queries the result of adjacent-channel power measurement.
POW:ACH:REF:AUTO ONCE
Defines the measured channel power as the reference value for relative power mea-
surements.
If the channel power only is to be measured, all commands relating to adjacent/alter-
nate channel bandwidth and channel spacings are omitted. The number of adjacent/
alternate channels is set to 0 with
