3Clean all optical interfaces as described in “Cleaning Connections for Accurate

Measurements” on page 4-10, before making measurements.

4Perform the following steps if you’re installing an Agilent 83492/3A module:

aUnscrew and remove the fiber-optic adapter that is located on the optical

module’s front-panel optical input connector.

bConnect the adapter that was removed in the previous step onto the

Agilent 83492/3A module’s front-panel Input connector.

On Agilent 83492A module’s, the input connector used depends on the

wavelength of the input signal. Refer to “To connect cables to an

Agilent 83492A” on page 1-7.

5Connect the supplied adapter cable as shown in Figure 1-3.

WARNING Light energy can radiate from the front pane l OUTPUT connectors on

Agilent 83492A and 83493A modules. The light emitted from these

connectors is the slightly attenuated light that is i nput to the front-

panel INPUT connector.

6Turn on the Agilent 83480A, and connect a modulated signal to the

Agilent 83491/2/3A module’s Input connector.
