[SENSe:]POWer:ACHannel:BWIDth:ALTernate<1...11>
<AltChannelBandwidth>
This command defines the bandwidth of the alternate channels.
If you set the channel bandwidth for the first alternate channel, the R&S Spectrum
Rider sets the bandwidth of the other alternate channels to the same value. The com-
mand works hierarchically: to set a bandwidth of the 10th and 8th channel, you have to
set the bandwidth of the 8th channel first.
Instead of BWIDwidth, you can also use the alias BANDth.
The suffix at ALTernate selects one of the 11 alternate channels.
Suffix:
<1...11>
.
1...11
Parameters:
<AltChBw>
*RST:
14 kHz
Default unit: GHz
Example:
[SENSe:]POWer:ACHannel:TXCHannel:COUNt
[SENSe:]POWer:ACHannel:MODE
<AdjacentChannelMode>
This command selects the way the R&S Spectrum Rider displays the power of adja-
cent channels.
The number of adjacent and alternate channels has to be greater than 0 for the com-
mand to work.
Parameters:
<AdjChMode>
ABSolute | RELative
ABSolute
Shows the absolute power of all channels..
RELative
Shows the power of adjacent and alternate channels in relation
to the transmission channel.
Example:
POW:ACH:MODE ABS
Shows absolute powers for all channels.
[SENSe:]POWer:ACHannel:PRESet:RLEVel
This command adjusts the reference level to the measured signal power.
This automatic routine makes sure that the that the signal power level does not over-
load the R&S Spectrum Rider or limit the dynamic range by too small a S/N ratio.
To determine the best reference level, the R&S Spectrum Rider aborts current mea-
surements and performs a series of test sweeps. After it has finished the test, it contin-
ues with the actual measurement.
This command is an event and therefore has no *RST value and no query.
