By default, the "Reference Receiver Cal Power" is set to the resulting
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
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 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..."

Controls in the Power Meter Transmission Coefficients Dialog
Test Setup
The button group on the right of the dialog allows you to select a test setup with an
additional two-port device. This device can be located in front of the DUT (during the
measurement) or in front of the power meter (during power calibration). "No Coeffi-
cients" disables the transmission coefficients but does not delete the entries in the
