●
"Cmp In" is the stimulus level at the compression point in units of dBm. "Cmp In"
always corresponds to the driving port level (e.g. the level from port no. j, if a trans-
mission parameter S
ij
is measured).
●
For dB formatted traces, "Cmp Out" is the sum of the stimulus level "Cmp In" and
the magnitude of the measured response value at the compression point. The
magnitude of a transmission S-parameter S
ij
is a measure for the attenuation (or
gain) of the DUT
, hence: "Cmp Out" = "Cmp In" + <Attenuation>.
For phase formatted traces, "Cmp Out" is the response value at the compression
point.
The info field shows invalid results ('----') if the wrong sweep type or trace format is
selected, or if no compression point with the configured properties was found.

Reference Value
This control is only available if compression point statistics are calculated. It selects the
reference value ("small signal value") for the compression point calculation.
"First Point"
(default)
uses the value at the first point of the selected evaluation range as
the reference value (see Chapter 5.5.8.2, "Evaluation Range dialog",
on page 415)
"Selected
Marker"
uses the value at a selectable marker as the reference value (see
"Selected Marker" on page 414)
"Range"
uses the average value in a configurable "Ref. Range" on page 415
as the reference value
"Defined
Value"
allows to specify the reference value manually (see "Defined Value"
on page 415)
Remote command:
CALCulate<Chn>:STATistics:NLINear:COMP:REFerence
Selected Marker
This button is only visible if "Selected Marker" is used as Reference Value. It allows
you to select the marker whose value shall be used as the reference ("small signal
value") for the compression point calculation.
