Press the Measurement main menu key and select the appropriate measurement. The setup instructions below apply to all cable and antenna measurements. For specific instructions on how to setup Distance-To-Fault, refer to Distance-To-Fault (DTF).

For accurate results, the instrument must be calibrated before making any measurements. The instrument must be re-calibrated whenever the temperature exceeds the calibration temperature range or when the test port extension cable is removed or replaced. Unless the calibration type is Flexcal, the instrument must also be re-calibrated every time the setup frequency changes. See Calibration for details on how to perform a calibration.
