Perform the Return Loss Measurement as follows:

ew 74 From the Lucent CDMA Tests Main Menu screen, select the Calibration/Utilities field. The Test Software will display the Calibration/Utilities Menu screen.

ew 84 Select the Return Loss Test field.

ew 94 If prompted to do so, remove the RF connections from the Test Set and press the k1 (Proceed) key to perform a channel power calibration. If channel power was recently calibrated, the Test Software might not prompt you to re-calibrate before starting the Return Loss test.

ew :4 Select the loss Measurement Type field and select the following:

•Swept will measure the loss over the frequency range that you specify in the Start Frequency and Stop Frequency settings. The Maximum Expected Loss for the device to be tested will be used to adjust the scale on the results plot. Use a value slightly greater than expected for the best display resolution. The Duplex Out Level into the device being tested may be adjusted if necessary.

•Discrete will measure the loss at the frequency that you specify by entering the

Channel Number to be tested.
