POW:ACH:SPAC:ALT1 100 KHZ
Sets the spacing between the alternate adjacent channels and the TX channel. For
details refer to [SENSe:]POWer:ACHannel:SPACing:ALTernate<channel>
on page 733.
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 [SENSe:]POWer:ACHannel:ACPairs
on page 730.
11.17.5 Occupied Bandwidth Measurement
In the following example, the bandwidth is to be found in which 95 % of the power of a
GSM signal is contained. Signal frequency is 935.2 MHz; channel bandwidth is 200
kHz.
