(1)   Input levels at +13.5 dBmV/CH (79 NTSC), plus digital after 550MHz at 6dB set-back.
(2)  50dBmv rev output level on each of 19,25,31MHz carriers,2nd order measured on 12MHz and 3rd order measured on 37MHz.
(3)   Noise Figure of the gain block, behind coupler losses.  Add 9dB for fwd input coupler loss,add 7.0dB for rev input splitter loss.
