Specification Document Number 1502211 Rev D
1. Spacing at highest frequency with Forward EQ installed. Return spacing includes losses due to housing, diplex
filters, and MEQ–42–X.
2. The specifications are based on the amplifier configured (with two SPB–0) as a 2–output bridger with distribution
outputs on Ports 3 and 6. When using distribution plug-ins SS–1000–2, SDC–1000–8 or SDC–1000–12, levels
should be derated accordingly based on the accessory specifications.
3. NTSC video channels occupying the appropriate frequency spectrum per specified number of channels.
4. Recommended minimum forward input levels at 1002MHz including loss due to equalizer.
5. Recommended maximum return output level at 42MHz including loss due to equalizer.
6. Forward trunk output levels achieved by installing an NPB-000 into the interstage PAD location and a
GEQC-1GHz-090 in the O/P EQ location. Forward bridger output levels are achieved by installing an NPB-020 in
the bridger EQ/PAD location.
7. Bridger output: At specified operational tilt the maximum output level for 870 or 1002MHz loading is 56.5dBmV
HF.
8. Distortion performance is derated accordingly to take into account the influence of the digitally compressed
channels operating at levels 6dB below equivalent video channels.
9. Cross modulation specification number indicates typical cascade performance.
10. Systems operating with digitally compressed channels or equivalent broadband noise from 550 to 1002MHz at
levels 6dB below equivalent video channels will experience a composite distortion (CIN) appearing in the 54 to
550 frequency spectrum.
