CALCulate<1|2>:LIMit<1 to 8>:ACPower:ACHannel[:RELative]:STATe ON | OFF
This command activates the limit check for the relative limit value of the adjacent channel when
adjacent channel power measurement is performed. Before the command, the limit check must be
activated using CALCulate:LIMit:ACPower:STATe ON.
The result can be queried with CALCulate:LIMit:ACPower:ACHannel: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.
The numeric suffixes <1 to 8> are irrelevant for this command.
Example: "CALC:LIM:ACP:ACH 30DB, 30DB" 'Sets the relative limit value in screen A for
'the power in the lower and upper adjacent
'channel to 30 dB below the channel 'power.
"CALC:LIM:ACP:ACH:ABS -35DBM, -35DBM"
'Sets the absolute limit value in screen A
'for the power in the lower and upper
'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 adjacent channels in 'screen A.
"CALC:LIM:ACP:ACH:ABS:STAT ON"'Switches on the check of absolute 'limit
values for the 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
'adjacent channels in screen A.

CALCulate<1|2>:LIMit<1 to 8>:ACPower:ACHannel:ABSolute -200DBM to 200DBM, -200 to 200DBM
This command defines the absolute limit value for the lower/upper adjacent channel during adjacent-
channel power measurement (Adjacent Channel Power) in the selected measurement window.
It should be noted that the absolute limit value has no effect on the limit check as soon as it is below
the relative limit value defined with CALCulate:LIMit:ACPower:ACHannel:RELative. This
mechanism allows automatic checking of the absolute basic values of adjacent channel power as
defined in mobile radio standards.
The numeric suffixes <1 to 8> in LIMIt are irrelevant for this command.
Parameter: The first value is the limit for the lower and the upper adjacent channel. The second limit
value is ignored but must be indicated for reasons of compatibiltiy with the FSE family.
Example: "CALC:LIM:ACP:ACH:ABS -35DBM, -35DBM"
'Sets the absolute limit value in 'screen
A for the power in the lower 'and upper
adjacent channel to '-35 dBm.
Characteristics: *RST value: -200DBM
