R&S FSQ Remote Control – Description of Commands
CALCulate Subsystem
CALCulate:LIMit:ACPower:ALTernate:ABSolute -200DBM to 200DBM,
-200DBM to 200DBM
This command defines the absolute limit value for the lower/upper alternate adjacent channel power
measurement (Adjacent Channel Power) in the selected measurement window.
The numeric suffix after ALTernate denotes the alternate channel. The numeric suffixes
are irrelevant for this command.
It should be noted that the absolute limit value for the limit check has no effect as soon as it is below
the relative limit value defined with CALCulate:LIMit:ACPower:ALTernate:
RELative. This mechanism allows automatic checking of the absolute basic values defined in mobile
radio standards for the power in adjacent channels.
Parameter: The first value is the limit for the lower and the upper alternate adjacent channel.
The second limit value is ignored but must be indicated for reasons of compatibility
with the FSE family.
Example: "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.
Characteristics: *RST value: -200DBM
SCPI: device-specific
Mode: A
CALCulate:LIMit:ACPower:ALTernate: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 denotes the alternate channel. The numeric suffixes
are irrelevant for this command.
The result can be queried with CALCulate:LIMit:ACPower:ALTernate: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.
