9530/8530 External Clock Operation
The 9530 pulse generator has a special external clock circuit that allows for external clock
synchronization when using clock sources that have very narrow pulse widths and amplitudes.
The circuit was designed to be used on the output of a photo-diode or equivalent current
source. The clock function will still operate if a voltage source is used if the parameters stated
below are observed.
