Note:
Risk of damage due to high power settings. If an external device (e.g. an ampli-
fier) is connected between the calibrated test port and the power meter, ensure that the
"Reference Receiver Cal Power" does not exceed its maximum input power.

Power Meter Transmission Coefficients dialog
The power calibration is taken at another reference plane compared to the system
error correction. This happens, e.g., in on-wafer measurements, but also at more trivial
things like using a simple attenuator to connect the power meter to the measurement
system.
Two scenarios have to be considered:
●
A two-port connected to the DUT which is not present during power calibration
(e.g. an on-wafer probe)
●
A two-port connected to the power Meter during the power calibration (e.g. an
adapter)
The "Power Meter Transmission Coefficients" dialog allows you to modify the results of
a scalar power calibration to account for these two-ports.

These buttons open the "Two Port Configuration" dialog that allows you to define the
transmission coefficients of additional two-port devices between VNA and DUT (during
the measurement), and between VNA and power meter (during power calibration). See
