1. A timing signal diagnostic system, comprising:
a chassis;
an input system that is included in the chassis and configured to receive a timing signal;
a timing system that is included in the chassis, coupled to the input system, and configured to receive the timing signal from the input system;
an analog-to-digital converter system that is included in the chassis, coupled to the input system, and configured to receive the timing signal from the input system; and
a processing system that is included in the chassis, coupled to the timing system and the analog-to-digital converter system, and configured to:
output, to the analog-to-digital converter system using the timing system, reference time signals that are based on the timing signal;
sample, using the analog-to-digital converter system, the timing signal based on the reference time signals over a plurality of different timing signal cycles;
generate, based on the sampling of the timing signal, a waveform for the timing signal; and
provide, based on the waveform for the timing signal, a timing signal diagnostic result.
