Follow this troubleshooting flowchart.

Description

Be sure all unused ports are properly terminated into 75 ohms to prevent mismatches. The

frequency response is cumulative and reflects the response of each active device in the link:

• The frequency response for the transmitter is dependent on the transmitter manufacturer's

specification.

• The frequency response of the node is ±1.0 dB from 52 MHz to 1218 MHz (for optical

receiver and amplifier combined).

It is possible that the RF amplifier is set up incorrectly. Always check to see that padding and

equalization is correct to ensure proper levels at the inputs to each gain stage. See the pad and

equalizer selection charts in

Technical Information

for correct pad and equalization.
