CALCulate<1|2>:LIMit<1...8>:ACPower:ALTernate<1...11>:ABSolute:STATe ON | OFF
This command activates the limit check for the alternate adjacent channels in the selected
measurement window for adjacent channel power measurement (Adjacent Channel Power).
Before the command, the limit check must be globally switched on for the channel/adjacent channel
power with the command
CALCulate:LIMit:ACPower:STATe ON
.
The numeric suffix after ALTernate<1...11> denotes the alternate channel. The numeric suffixes
<1...8> are irrelevant for this command.
The result can be queried with
CALCulate:LIMit:ACPower:ALTernate<1...11>:RESult?
. It
should be noted that a complete measurement must be performed between switching on the limit
check and the result query, since otherwise no valid results are available.
Example:
"CALC:LIM:ACP:ALT2 30DB, 30DB"
'Sets the relative limit value in screen A for the power in the lower and upper
second alternate adjacent channel to 30 dB below the channel power.
"CALC:LIM:ACP:ALT2:ABS -35DBM, -35DBM"
'Sets the absolute limit value in screen A for the power in the lower and upper
second alternate adjacent channel to -35 dBm.
"CALC:LIM:ACP ON"
'Switches on globally the limit check for the channel/adjacent channel
measurement in screen A.
"CALC:LIM:ACP:ACH:REL:STAT ON"
Switches on the check of the relative limit values for the alternative adjacent
channels in screen A.
"CALC:LIM:ACP:ACH:ABS:STAT ON"
'Switches on the check of absolute limit values for the alternative adjacent
channels in screen A.
"INIT;*WAI"
'Starts a new measurement and waits for the sweep end.
"CALC:LIM:ACP:ACH:RES?"
'Queries the limit check result in the second alternate adjacent channels in
screen A.

CALCulate<1|2>:LIMit<1...8>:ACPower:ALTernate<1...11>[:RELative] 0 to 100dB, 0 to 100dB.
This command defines the limit for the alternate adjacent channels 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...11> denotes the alternate channel. The numeric suffixes
<1...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 the
absolute limit defined with
CALCulate:LIMit:ACPower:ALTernate<1...11>:ABSolute
. This
mechanism allows automatic checking of the absolute basic values of adjacent channel power as
defined in mobile radio standards.
