2. Implementing Receiver Calibration
Receiver calibration is required for the absolute measurement. Receiver calibration of the
port to be used for the measurement increases the accuracy in the absolute measurement.
For detailed information on receiver calibration, see "Receiver Calibration" on page 220.
3. Setting Absolute Measurement Parameters
The frequency-offset function has an added absolute measurement function.
