The Scalers further divide the time and event pulses for application
to the Arithmetic Processor where the counting process occurs prior to
display time.
The Gate Control circuits control the various methods of
arming the counter.
The State Control circuits determine the particular
program which outputs instructions to the various assemblies in the counter.
The counter's time base (500 MHz) is supplied by a precise 10 MHz oven-
controlled crystal oscillator.
