By default, the "Reference Receiver Cal Power" is set to the resulting Port Cal Power.
However, the accuracy of the source power calibration depends on the power meter's
measurement accuracy. Therefore it is advantageous to select a "Reference Receiver
Cal Power" at which the power meter provides maximum accuracy.
The "Reference Receiver Cal Power" is also used for the power calibration step in a
SMARTerCal; see Chapter 4.5.7, "SMARTerCal", on page 197.
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.

5.11.3.3 Power Meter Transmission Coefficients dialog
The "Power Meter Transmission Coefficients" dialog allows you to modify the results of
a scalar power calibration to account for an additional two-port device (with known
transmission characteristics) in the test setup.
Access: Channel – [Cal] > "Pwr Cal Settings" > "Transm. Coefficients..."
