R&S FSP Remote Control – Description of Commands
CALCulate Subsystem
6.30 Operating Manual 1164.4556.12 - 06
6.5.5.2 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: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...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 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<1|2>:LIMit<1...8>: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 <1...8> in LIMIt are irrelevant for this command.
