SCPI Command Reference
Operating Manual 1145.1084.12 – 30 686
SCPI, Command Types
Device-specific, command or query.
Example:
See CALCulate<Chn>:STATistics:[:STATe]
CALCulate<Chn>:STATistics:NLINear:COMP:LEVel <compression_value>
Defines the compression value x for the x-dB compression point measurement (enabled via
CALCulate<Chn>:STATistics:MSTDdev[:STATe] ON).
<Chn>
Channel number used to identify the active trace.
<compression_value>
Compression value.
Range [def. unit]
+0.01 dBm to +100.00 dBm [dBm]
*RST value
1 dBm
SCPI, Command Types
Device-specific, command or query.
Example:
See CALCulate<Chn>:NLINear:COMP:RESult?
CALCulate<Chn>:STATistics:NLINear:COMP:RESult?
Returns the x-dB compression point of an S-parameter or ratio measured in a power sweep, where the
compression value x is set via CALCulate<Chn>:STATistics:NLINear:COMP:LEVel.
In order to get more accurate results the command should be preceded by activation of enhanced
compression point measurement via CALCulate<Chn>:STATistics:NLINear:COMP[:STATe]. The
accuracy depends on the state set by this command:
 If set to ON, the enhanced calculation method is activated which uses the explicitly measured
reference receiver value of the driving port as input power.
 If set to OFF, the calculation can use only the nominal stimulus power of the trace for calculation.
But the nominal input power may differ slightly from the real input power especially if no flatness
calibration or ALC is applied to the driving port
<Chn>
Channel number used to identify the active trace.
Result
<Cmp_In>, <Cmp_Out>
<Cmp_In> is the stimulus level at the compression point
<Cmp_Out> is the magnitude of the wave reflected or transmitted by the DUT.
Range [def.
unit]
For <Cmp_In>: Current sweep range or evaluation range
(CALCulate<Chn>:STATistics:DOMain:USER), if different from the sweep
range. [dBm]
For <Cmp_Out>: Measurement range of the analyzer. [dBm]

Types

*RST; SWE:TYPE POW
Select a power sweep with default CW frequency and sweep range.
