6.5.4.3 CALCulate:MARKer:FUNCtion:POWer Subsystem
The CALCulate:MARKer:FUNCtion:POWER subsystem contains the commands for control of power
measurement.
CALCulate<1|2>:MARKer<1...4>:FUNCtion:POWer:SELect ACPower | CPOWer | MCACpower |
OBANdwidth | OBWidth | CN | CN0
This command selects – and switches on – one of the above types of power measurement in the
selected measurement window. This function is independent of the selected marker, i.e. the numerical
suffix <1...4> appended to MARKer has no effect.
The channel spacings and channel bandwidths are configured in the SENSe:POWer:ACHannel
subsystem.
Please note the following:
If CPOWer is selected, the number of adjacent channels (command: [SENSe:]POWer:ACHannel:
ACPairs) is set to 0. If ACPower is selected, the number of adjacent channels is set to 1, unless
adjacent channel power measurement is switched on already.
This command is a query and therefore has no *RST value.
The channel/adjacent channel power measurement is performed for the trace
selected with SENSe:POWer:TRACe 1|2|3.
The occupied bandwidth measurement is performed for the trace on which marker 1 is positioned. To
select another trace for the measurement, marker 1 is to be positioned on the desired trace by means
of CALC:MARK:TRAC 1|2|3.
Parameter: ACPower: adjacent channel power measurement with a single carrier signal
CPOWer: Channel power measurement with a single carrier signal (equivalent to
adjacent channel power measurement with NO. OF ADJ CHAN = 0)
MCACpower: Channel/adjacent channel power measurement with several carrier
signals
OBANdwidth | OBWidth: Measurement of occupied bandwidth
CN: Measurement of carrier-to-noise ratio
CN0: Measurement of carrier-to-noise ratio referenced to 1 Hz bandwidth
Example:
"CALC:MARK:FUNC:POW:SEL ACP"
'Switches on adjacent channel power measurement in window A.
Characteristics: *RST value: -
SCPI: device-specific
Mode: A-F
