Manual operation:
See
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
, 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>
–
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
Suffix:
<Chn>
.
Channel number used to identify the active trace
Example:
*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.
CALC:STAT:NLIN:COMP ON
Display the compression point result in the diagram area.
Usage:
Query only
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
CALCulate<Chn>:STATistics:NLINear:COMP:REFerence
set to
DVALue
. For phase formatted traces, the reference level can be set using
CALCulate<Chn>:STATistics:NLINear:COMP:RPHase
.
Suffix:
<Chn>
.
Channel number used to identify the active trace
Parameters:
