Specification Document Number 1502212 Rev C
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 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. Bridger output: At specified operational tilt the maximum output level for 870MHz or 1002GHz 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 54 to
550 frequency spectrum.
