CALCulate<1|2>:LIMit<1 to 8>:ACPower[:STATe] ON | OFF
This command switches on and off the limit check for adjacent channel power measurements in the
selected measurement window. The commands CALCulate:LIMit:ACPower:ACHannel:STATe or
CALCulate:LIMit:ACPower:ALTernate:STATe must be used in addition to specify whether the limit
check is to be performed for the upper/lower adjacent channel or for the alternate adjacent channels.
The numeric suffixes <1 to 8> are irrelevant for this command.
Example: "CALC:LIM:ACP ON" 'Switches on the ACP limit check in screen A.
Characteristics: *RST value: OFF
SCPI: device-specific
Mode: A
CALCulate<1|2>:LIMit<1 to 8>:ACPower:ACHannel[:RELative] 0 to 100dB, 0 to 100dB
This command defines the relative limit of the upper/lower adjacent channel for adjacent channel
power measurements in the selected measurement window. The reference value for the relative limit
value is the measured channel power.
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 value defined with CALCulate:LIMit:ACPower:ACHannel:ABSolute. 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> are irrelevant for this command.
Parameter: The first numeric value is the limit for the upper (lower) adjacent channel. The
second value is ignored but must be indicated for reasons of compatibility with the
FSE family.
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.
Characteristics: *RST value: 0 dB
SCPI: device-specific
Mode: A
