The purpose of the forward interstage equalizer in state-of-art HFC systems is to:

{a} Help compensate for the cable preceding the amplifier station.

{b} reduce the contribution of the distortion produced by the output stage(s) of the amplifier (for a given output level at the highest frequency)

{d} Determine the amplifier station's output tilt.

{c} All the the above

One way to determine if a sweep problem is in the amplifier or before the amplifier is to:

A. Check the sweep at the both the Main and the AUX test-point

B. Check whether the problem exists in both forward and reverse sweep.

C. Compare the sweep response to the Scan response.

D. Compare sweep at the output to sweep at the input.

D. Compare sweep at the output to sweep at the input.

What is the main purpose of sweep in an HFC preventive maintenance program?

A. To setup the amplifiers and flatten their response.

B. To ensure that plant is kept repaired and in good order.

C. To troubleshoot the reverse path, and ensure reverse unity gain.

D. Set up the network and tag node and amplifier stations.

On which channels/bands is a sweep response derived without actual insertion of sweep energy?

A. All forward and reverse analog channels.

B. On all forward and reverse analog and digital channels.

C. Reverse band only.

D. Forward analog channels only.

In reverse sweep:

A. The sweep system uses existing reverse carriers to measure reverse response.

B. The field unit injects sweep pulses that are received upstream by the headend unit.

C. The headend unit and field unit telemetry channels are diffenerent frequencies.

D. None of the above

An amplifier's forward output tilt produced by its equalizer (or equalizers) is:
