Looking at raw measurements performed by supported receivers

[marcvb]

When the RF analyzer is set to Correction Level: None, it will perform uncalibrated measurements. The receiver data connected to the coupler sampling the incident wave gets stored in the "Voltage" variable and the reflected wave from the port gets stored into the "Current" variable.

In this way knowing approximately the losses and coupling factors and assuming one uses reasonable good couplers, one can get an idea of what goes towards and comes from the port. For certain receivers the value is not at all calibrated and absolute value has no meaning.

This can be confusing as the "A" and "B" variable are NOT representative for the raw receiver measurements.

As long as no valid calibration is done, any derived quantity is wrong and not representative.
