3.6 Monitoring the Input/Output Signal

The Receiver’s RF signal strength can be monitored during operation via a

DC RF signal-strength monitor. Maintenance personnel can perform a

simple verification process.

To measure the RF signal strength:

1. Using a Digital Volt Meter, measure the voltage at the connector pin #4

(both Rackmount and Standalone).

3.7 Aligning the Fiberoptic Link

The final step in installing the 7410F IFL is re-adjusting the Receiver Gain

Control for unity gain.

To set the unity gain:

1. Set the Signal Generator to -20 dBm on the S.A. at 1000 MHz

2. Set up the system as shown in Figure 12.

3. Adjust the Receiver Gain Control for unity gain.
