Manual operation:
CALCulate<Chn>:STATistics:NLINear:COMP:RESult?
Returns the compression point of an S-parameter or ratio measured in a power sweep.
For dB formatted traces, the compression value x is set via
STATistics:NLINear:COMP:LEVel, for phase formatted traces it is set via
CALCulate<Chn>:STATistics:NLINear:COMP:PHASe.
The response contains two numeric values:
● <Cmp In> – stimulus level at the compression point in dBm.
●
<Cmp Out>
–

Suffix:
<Chn>

Usage:
Manual operation:
CALCulate<Chn>:STATistics:NLINear:COMP:RLEVel <Level>
Manually defines the reference level for compression point calculation on dB formatted
traces.
This only applies if
set to DVALue. For phase formatted traces, the reference level can be set using
CALCulate<Chn>:STATistics:NLINear:COMP:RPHase.
Suffix:
<Chn>

For dB formatted traces, the sum of <Cmp In> plus the magnitude of the mea-
sured response value at the compression point in dBm.
For phase formatted traces, the response value at the compression point

Channel number used to identify the active trace
*RST; SWE:TYPE POW
Select a power sweep with default CW frequency and sweep
range.
CALC:STAT:NLIN:COMP:LEV 2
Define a compression value of 2 dB.
CALC:STAT:NLIN:COMP:RES?
Query the compression point results <Cmp In>, <Cmp Out>. An
execution error message (error no. -200) is returned if no com-
pression point is found.
