Specification Document Number 1502213 Rev D
1. Spacing at highest frequency with SEQ–1G–XX 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 2 and 3. 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. At specified operational tilt maximum output level for 870MHz or 1GHz loading is 56.5dBmV @ HF.
7. Distortion performance is derated accordingly to take into account the influence of the digitally compressed
channels operating at levels 6dB below equivalent video channels.
8. Cross modulation specification number indicates typical cascade performance.
9. 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 54to 550
frequency spectrum.
10. Systems operating with digitally compressed channels or equivalent broadband noise from 550 to 870MHz at
levels 6dB below equivalent video channels will experience a composite distortion (CIN) appearing as noise in the
54 to 550MHz frequency spectrum.
11. The Noise Figure and C/N specifications are typical within specified passband.
12. The forward bridger port gain and flatness (ports 2, 3, and 5 only) is 0 ±1.0dB as referenced to port 6.
13. The return bridger port gain and flatness (ports 2, 3, and 5 only) is 0 ±0.5dB as referenced to port 6.
