Notes:
1. Operating passband of station. Diple x filters are plugged into the electronic chassis.
2.
Referenced to the average gain across the stated passband.
3.
Minimum full gain at 870 MHz includes loss of equalizer but Bode slope reserves have not been set. Return gain includes loss of SRE -*-4 return
equalizer.
4.
Operational gain includes loss of slope reserves as well as equalizer.
5.
Amount of Bode slope control range from midpoint (typical setting is -4 dB at 870 MHz @ 20°C). This control should not be used for gain
reduction.
6.
Amount of slope created and cable equivalence of fixed interstage equalizer. Interstage equalizer is a plug -in.
7.
Noise Figure performance is specified typical. Noise Figure is specified at the cable entry facility of the housing and includes the loss of 1 dB for
the pre-stage equalizer. The return Noise Figure includes the station loss preceding the RF hybrid.
8.
Frequencies that relate the picture carriers or passband edges to the specified output levels and tilts.
9.
Measured with CW carriers and spectrum analyzer over specified temperature range. References the worst-case channel. Specifications are
compliant with the test methods as stated in NCTA RECOMMENDED PRACTICES FOR MEASUREMENTS ON CABLE TELEVISION
SYSTEMS.
10.
Measured with wave analyzer and synchronous, 100% depth modulated channels. References the worst -case channels over specified
temperature range. Specifications are compliant with the test methods as stated in NCTA RECOMMENDED PRACTICES FOR
MEASUREMENTS ON CABLE T ELEVISION SYSTEMS.
11.
Composite Second Order distortion refers only to those beat clusters that fall +0.75 MHz and +1.25 MHz above the subject picture carrier. CSO
beat clusters that have a -0.75 MHz and -1.25 MHz relationship to the subject picture car rier are not included in this specification.
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.
17.
Current draw at +24.0 VDC.
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 typic al. 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.
