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 1.2 GHz GS7000 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 Appendix A for correct
pad and equalization.
