Example: CALC:MARK:FUNC:POW:RES:PHZ ON
Output of results referred to the channel bandwidth.
Manual operation: See "Channel Power Levels and Density (Power Unit)"
on page 154
[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
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 153
11.5.3.10 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 ............................722
● Example: Configuring and Performing an MSR ACLR Measurement ...................724
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---------------------
*RST
//Resets the instrument
INIT:CONT OFF
//Selects single sweep mode.
CALC:MARK:FUNC:POW:SEL ACP
//Activates adjacent-channel power measurement.
CALC:MARK:FUNC:POW:PRES GSM
//Selects the user standard "GSM"
//---------------Setting Up Channels------------
POW:ACH:TXCH:COUN 1
//Creates one transmission channel.
