R&S FSP Remote Control – Description of Commands
CALCulate Subsystem
CALCulate<1|2>:STATistics:SCALe:AUTO ONCE
This command optimizes the level setting of the instrument depending on the measured peak power,
in order to obtain maximum instrument sensitivity.
To obtain maximum resolution, the level range is set as a function of the measured spacing between
peak power and the minimum power for the APD measurement and of the spacing between peak
power and mean power for the CCDF measurement. In addition, the probability scale for the number
of test points is adapted.
+
Example:
"CALC:STAT:SCAL:AUTO ONCE;*WAI"
'
Adapts the level setting for statistical measurements and activates the
synchronization.
Characteristics: *RST value: --
SCPI: device-specific
Mode: A
This command is an event and therefore has no *RST value and no query.
CALCulate<1|2>:STATistics:SCALe:X:MPOSition 0 … 100
This command defines the relative X position of the mean power value for the CCDF measurement.
The default position is 0% (left corner of the grid). This function is only available if the statistics
measurement function CCDF is switched on.
Example:
"CALC:STAT:SCAL:X:MPOS 10.0"
' set the mean power position to 10%
Characteristics: *RST value: 0
SCPI: device-specific
Mode: A
CALCulate<1|2>:STATistics:SCALe:X:RANGe 1dB to 200dB
This command defines the level range for the x-axis of the measurement diagram. The setting is
identical to the level range setting defined with the command
DISPlay:WINDow:TRACe:Y:SCALe
.
Example:
"CALC:STAT:SCAL:X:RANG 20dB"
Characteristics: *RST value: 100dB
SCPI: device-specific
Mode: A
Subsequent commands have to be synchronized with
*WAI
,
*OPC
or
*OPC?
to the
end of the auto range process which would otherwise be aborted.
