R&S FSQ Remote Control – Description of Commands
6.5.5.2 CALCulate:LIMit:ACPower Subsystem
CALCulate Subsystem
The CALCulate:LIMit:ACPower subsystem defines the limit check for adjacent channel power measurement.
CALCulate:LIMit: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 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 compatibility 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
SCPI: device-specific
Mode: A
CALCulate:LIMit:ACPower:ACHannel:ABSolute:STATe ON | OFF
This command activates the limit check for the adjacent channel when adjacent channel power
measurement (Adjacent Channel Power) is performed. Before the command, the limit check for the
channel/adjacent channel measurement must be globally switched on using CALC:LIM:ACP 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 in LIMIt 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.
