6.Press PARAM to select the [lambda] parameter. Edit this parameter and set it to the current wavelength of the source.

7.Enable the source.

8.Press PARAM to select the CAL REF parameter (the current value for the known return loss is displayed with R: at the side of the character field).

9.Attach the Agilent 81000BR Reference Reflector to the patchcord. (Use the Agilent 81000UM, with a connector interface to do this)

10.Set the reflection reference (R:) to 0.18dB, the default value of the return loss of the reference reflector.

11.Press DISP→ REF (the value read should now be 0.18dB, the same as the value entered for R:).

If this is the first time that you have transferred this value to the reference after switch on, it might not be displayed properly. In this case, repeat the step to correct the display.

12.Press PARAM to select the REF AUX parameter.

13.Terminate the cable by wrapping the fiber five times around the shaft of a screwdriver.

14.Press DISP→ REF (the instrument sets the termination parameter).

15.Disable the DUT.

If you have the monitor option (option 121), make sure that the cable at the monitor output is terminated.

16.Connect the 81109AC patchcord to the 8156A input, and note the Return Loss result in the Test Record.

17.Connect the 81109AC patchcord to the 8156A output, and note the Return Loss result in the Test Record.
