J17 is a three-pin by twenty header that is used to establish input levels for the pin controlled three-level inputs
using jumper plugs. It also provides a means of externally driving the three-level input signals.
J18 is used to monitor the Any-Frequency Precision Clock voltage.
J1 and J2 are edge mount SMA connectors that are used, if so configured, to supply an external single-ended or
differential reference oscillator.
