R&S ESU Remote Control – Description of Commands
CALCulate Subsystem
6.5.3.1 CALCulate:LIMit:ACPower Subsystem
The CALCulate:LIMit:ACPower subsystem defines the limit check for adjacent channel power measure-
ment.
CALCulate<1|2>:LIMit<1...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...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...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...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
CALCulate<1|2>:LIMit<1...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...8> are irrelevant for this command.
