Applications The Return Loss Application
262 Agilent 8163A/B, 8164A/B, and 8166A/B User’s Guide, Fourth Edition
The Return Loss Application
NOTE The Return Loss Application supports the Agilent 81610A-81614A
Return Loss Modules. The Application is not available for the Agilent
8164A/B Lightwave Measurement System or the Agilent 8166A/B
Lightwave Multichannel System.
The Return Loss application allows measurement of Return Loss
and/or Insertion Loss. Both values are displayed on the Agilent
8163A/B Lightwave Multimeter at the same time, depending on the
calibration and configuration status. In addition, the Return Loss
Application provides a simple step-by-step guided procedure for
calibration of the instrument.
Starting the Application
As the other applications, the Return Loss Application can be
configured to start up automatically. Alternatively, it can be started by
pressing the “Appl” hardkey on the front of the Agilent 8163A/B
Lightwave Multimeter.
Measuring Return Loss
To measure return loss, insert a Return Loss Module into the Agilent
8163A/B Lightwave Multimeter Multimeter and connect it to the
Device under Test (DUT). The Return Loss value is displayed on the
Multimeter. You can freeze the measurement value during
measurement either by pressing the “Hold/Cnt” softkey or by using a
foot pedal if this option has been enabled via the “Config” hardkey.
(See “How to Configure your Foot Pedal” on page 67 for further
details). For general information on measuring Return Loss, please
refer to “Return Loss Measurement” on page 147.
