Notes:
1. Factory alignment with 10dB cable equivalent, 3 dB of Interstage pad and 30 dB of flat gain. Gain dependant on reverse hybrid selection.
2. All return loss measurements made with 0 dB pads and a #18 gauge wire jumpers in place of the equalizers.
3. Distortion measurements made with 77 analog channels and 33 digital channels running 6 dB down from an analog equivalent.
4. Resistive -20 dB test points on the housing
