Disc Control - Short for disciplining control, this disciplining function is the part of the software that matches the local clock phase and frequency with the selected time reference function.
Phase Control - Short for local clock phase shifting, this function shows if the software is shifting the
Disc Gain - Short for oscillator disciplining function gain value, this is a scalar value that sets the gain for the Kalman filter so it can discipline the local oscillator to the selected time reference.

They are:
HeartBeat Mode - The heartbeat is the specified frequency.
HeartBeat Counter1 and 2 - These are internal counters to the timing engine. Frequency Output - The available frequencies are 1, 5, and 10 MHz.
Event Control - This setting enables or disables the ability of the internal clock to capture the time at which an external event occurs.
Event Edge - This is either the rising or falling edge of the heartbeat signal.
Event Capture Lockout - If enabled, the capture lockout can be used to control whether or not subsequent signals will overwrite the data in the timing engine’s event time registers.
Event Capture Source - This setting controls the source of the external
