Src Port 1" is the ratio of the outgoing wave at DUT port 2 and the incident
wave at DUT port 1 (i.e. DUT port 1 ist stimulated). This corresponds to the forward
transmission coefficient S

Detector Settings
The "Detector" settings select the algorithm that is used to calculate the displayed
measurement points from the raw data. The "Detector" can be selected in the "More
Wave Quantities" and More Ratios dialogs.

The following detectors are available:
●
"Normal"
selects the default detector mode where each valid measurement point
is displayed without modification. The analyzer then proceeds to the next sweep
point. Normal detector mode ensures that the measurement is performed at maxi-
mum speed and that a meaningful complex result is obtained.
●
"AVG Real Imag"
collects all valid results at each sweep point during the "Detector
Meas Time" set in the "More Wave Quantities" or More Ratios dialog and calcu-
lates the complex arithmetic mean of their real and imaginary parts.
●
AVG Mag Phase
collects all valid results at each sweep point during the "Detector
Meas Time" set in the "More Wave Quantities" or More Ratios dialog. It calculates
the arithmetic mean of the magnitude and phase values of these results separately.
