1-Port Calibration Procedure (OSL)
1. If a test port extension cable is to be used, connect the cable to the RF Out connector on the BTS Master. The calibration components will be connected at the end of the cable (Figure: 1-Port Calibration).
2. Set the frequency range, refer to Frequency for additional information.
3. Press the Shift key and then the Calibrate (2) key.
4. On the Cal Mode submenu key, select Standard or FlexCal.
FlexCal is a broadband calibration that allows you to change the frequency after calibration. It is more time efficient and particularly helpful if you are troubleshooting the system. For optimum accuracy, the Standard Cal method is recommended.
5. Verify that the Device Under Test (DUT) connector, as shown on the DUT Connector submenu key, is appropriate for the test setup. To choose a different connector, press the DUT Connector submenu key and use the rotary knob or Up/Down arrow keys to highlight the appropriate connector and press the rotary knob or Enter to select.
