OBWidth
Measurement of occupied bandwidth
The occupied bandwidth in Hz is returned.
PPOWer Power of the highest peak
In a Spectrum Emission Mask measurement, the query returns the power
result for the reference range, if this power reference type is selected.
Example of channel/adjacent–channel power measurement
POW:ACH:ACP 3
Sets the number of adjacent/alternate channels to 3.
POW:ACH:BAND 30KHZ
Sets the bandwidth of the transmission channel to 30 kHz.
POW:ACH:BAND:ACH 40KHZ
Sets the bandwidth of each adjacent channel to 40 kHz.
POW:ACH:BAND:ALT1 50KHZ
Sets the bandwidth of each alternate channel to 50 kHz.
POW:ACH:BAND:ALT2 60KHZ
Sets the bandwidth of alternate channel 2 to 60 kHz.
POW:ACH:SPAC 30KHZ
Sets the spacing between the transmission channel and the adjacent channel to 30 kHz, the
spacing between the transmission channel and alternate channel 1 to 60 kHz, and the spacing
between the transmission channel and alternate channel 2 to 90 kHz.
POW:ACH:SPAC:ALT1 100KHZ
Sets the spacing between the alternate adjacent channels and the TX channel. For details refer
to the [SENSe<1|2>:]POWer:ACHannel:SPACing:ALTernate<1...11> command.
POW:ACH:SPAC:ALT2 140KHZ
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 measurements.
Note: If the channel power only is to be measured, all commands relating to
adjacent/alternate channel bandwidth and channel spacings are omitted. The number of
adjacent/alternate channels is set to 0 with
[SENSe<1|2>:]POWer:ACHannel:ACPairs.
