20. Enter the measurement frequency (0.1 MHz) into the power meter to enable cal factor
(frequency) correction.
Note
The recommended power meter has power sensor calibration factors stored
internally in the sensor. Setting the input frequency in the power meter
automatically selects the appropriate cal factor for the measurement.
However, the power sensor may also be accompanied by a table of
calibration factors which must be applied externally.
