CALCulate<1|2>:LIMit<1 to 8>:ACPower:ALTernate<1|2>[:RELative] 0 to 100dB, 0 to 100dB.
This command defines the limit for the first/second alternate adjacent channel in the selected
measurement window for adjacent channel power measurements. The reference value for the
relative limit value is the measured channel power.
The numeric suffix after ALTernate<1|2> denotes the first or the second alternate channel. The
numeric suffixes <1 to 8> are irrelevant for this command.
It should be noted that the relative limit value has no effect on the limit check as soon as it is below th
absolute limit defined with CALCulate:LIMit:ACPower:ALTernate<1|2>:ABSolute. This
mechanism allows automatic checking of the absolute basic values of adjacent channel power as
defined in mobile radio standards.
Parameter: The first value is the limit for the lower and the upper alternate adjacent channel.
The second limit value is ignored but must be indicated for reasons of
compatibility with the FSE family.
Example: "CALC:LIM:ACP:ALT2 30DB, 30DB" 'Sets the relative limit value in
'screen A for the power in the lower
'and upper alternate adjacent
'channel to 30 dB below the channel
'power.
