Connections

The I (in-phase video) signal from the demodulator is connected to the B CPNT input Y

signal BNC connector (see Figure 11-5). The other BNC connector of the loop through is

connected with a short cable to the B CPNT input R-Y and terminated at the other connector

with a 75 Ω terminator. Note that the I signal is a low pass video signal and that some

demodulators only have a video output that can be used with a low pass filter.

The Q (Quadrature phase video) signal is routed though a 250 KHz termimated low pass filter

to the B-Y input.
