NOTES:
(1) As measured with 5 dB pads at each input port.
(2) Output levels of 23 dBmV/channel, 79 CW NTSC analog channels from 54-550 MHz with 450 MHz QAM loading 6 dB below analog carrier levels.
(3) This is the noise figure of the gain stage only. Like any active combiner, must add input pad value (5 dB) and 8-way combiner loss (12 dB), yielding typical net noise figure of < 25 dB.
(4) DC load current at +24 VDC.

NOTES:
(1) As measured with 5 dB pads installed at each NC input port.
(2) Output levels of 23 dBmV/channel, 79 CW NTSC analog channels from 54-550 MHz with 450 MHz QAM loading 6 dB below analog carrier levels.
(3) This is the noise figure of the gain stage only. Like any active combiner, must add input pad value (5 dB) and 8-way combiner loss (12 dB), yielding typical net noise figure of < 25 dB.
(4) DC load current at +24 VDC.
OTHER NOTES:
Note that NC to BC measured goes through a gain stage, so measurement appears high.
Minimum/maximum composite RF detection level in software is 20.5/80 dBmV.
