Each input channel has a separate attenuator module containing passive 1 megohm attenuators, a 50 ohm termination resistor, an AC coupling capacitor, a switch selecting the calibrator or signal input, and an [[M474]] buffer amplifier. In normal operation the calibrator signal to the attenuator is instead connected to ground.

The attenuator module output feeds the + input of the [[M377]] amplifier IC through a (blue) 50 ohm transmission line, one per input channel.  The cable lengths set a standard delay per plugin.
