LINE EXTENDER

12.CCN (Composite, Carrier-to-Noise Ratio) is a 10 log addition of both the

Carrier-to-Noise Ratio (CNR) and Carrier-to-Intermodulation Noise Ratio

(CIN).

13.Test points should be used with GFAL adaptor.

14.Match measurement at the station input and output, cable-entry facilities,

at the specified passbands for operational gain.

15.Measured with the stated AC Bypass Current.

16.Measured at the power connector.

18.AC current is stated in RMS continuous.

19.Group Delay is specified for standard NTSC video, where delay is the

delta from picture carrier to 3.58 MHz color subcarrier. Reverse delay is in

a 1.5 MHz bandwidth.

20.Hum Modulation performance is stated typical. Return band specified

from 15 MHz. Hum Modulation (5 MHz to 15 MHz) is –55 dBc.

21.Distortion numbers are worst case over temperature in a cascade.

22.The compressed data loading is QAM carriers and are –6 dB relative to

the analog CW carriers.

23.CTB (Composite Triple Beat). At the specified channel loading, Enhanced

Gallium Arsenide performance varies on a two point three-for-one (2.3:1)

basis with amplifier output level.
