CALCulate<n>:LIMit<li>:ACPower:ACHannel[:RELative] <LowerLimit>[,
<UpperLimit>]
This command defines the relative limit of the adjacent channels. The reference value
for the relative limit is the measured channel power.
If you have defined an absolute limit as well as a relative limit, the R&S FSW uses the
lower value for the limit check.

CALCulate<n>:LIMit<li>:ACPower:ACHannel:RESult?
This command queries the state of the limit check for the adjacent channels in an
ACLR measurement.
To get a valid result, you have to perform a complete measurement with synchroniza-
tion to the end of the measurement before reading out the result. This is only possible
for single sweep mode.
