1...12
the TX channel
Parameters:
<Name> *RST: TX<1...12>
Example:
POW:ACH:NAME:CHAN3 'XYZ'
Defines the name of the third transmission channel as 'XYZ'.
Manual operation: See "Names" on page 329
[SENSe:]POWer:ACHannel:PRESet
<Setting>
This command adjusts the frequency span, the measurement bandwidths and the
detector as required for the number of channels, the channel bandwidths and the chan-
nel spacings selected in the active power measurement. If necessary, adjacent-chan-
nel power measurement is switched on prior to the adjustment.
To obtain correct results, a complete sweep with synchronization to the end of the
sweep must be performed after the adjustment. Synchronization is possible only in the
single sweep mode.
The result is queried with the CALCulate<n>:MARKer<m>:FUNCtion:POWer:
RESult? command.
Parameters:
<Setting> ACPower | CPOWer | MCACpower | OBANdwidth | OBWidth |
CN | CN0
Example:
POW:ACH:PRES ACP
Sets the frequency span, the measurement bandwidths and the
detector as required for the ACLR 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 the adjacent-channel power measurement.
Manual operation: See "Adjust Settings" on page 331
See "Adjust Settings " on page 340
[SENSe:]POWer:ACHannel:PRESet:RLEVel
This command adapts the reference level to the measured channel power and – if
required – switches on previously the adjacent channel power measurement. This
ensures that the signal path of the instrument is not overloaded. Since the measure-
ment bandwidth is significantly smaller than the signal bandwidth in channel power
measurements, the signal path can be overloaded although the trace is still signifi-
cantly below the reference level. If the measured channel power equals the reference
level, the signal path is not overloaded.
