Manual operation: See "Channel power level and density (Power Unit)"
on page 172
[SENSe:]POWer:ACHannel:MODE <Mode>
This command selects the way the R&S FSW displays the power of adjacent channels.
You need at least one adjacent channel for the command to work.
Parameters:
<Mode> 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
*RST:
RELative
Manual operation: See "Absolute and Relative Values (ACLR Mode)" on page 172
14.5.3.10 Programming Examples for Channel Power Measurements
The following programming examples are meant to demonstrate the most important
commands to perform channel power measurements in a remote environment.
● Example: Configuring and Performing an ACLR Measurement ............................891
● Example: Configuring and Performing an MSR ACLR Measurement ...................893
● Example: Configuring and Performing an Asymmetrical MSR ACLR Measurement
.............................................................................................................................. 895
Example: Configuring and Performing an ACLR Measurement
In this example we will configure and perform an adjacent-channel power measure-
ment. Note that this example is primarily meant to demonstrate the remote control
commands, it does not necessarily reflect a useful measurement task. For most com-
mon measurement standards, the R&S
FSW performs the measurement optimally with
the predefined settings, without further configuration.
//-----------Preparing the measurement ------------
//Reset the instrument
