Abstract
Some options for incorporating timing control into experiments were explored, and an attempt was made to illustrate how the use of a hardware clock can often simplify the software requirements. A series of flow charts was provided which can be used as a starting point by the scientific/engineering user as a basis for high precision timing using the Metrabyte CTM-05 Counter/Timer Interface Card. The frame of reference for this discussion was the IBM Personal Computer and equivalent computers. With experience many sophisticated timing regimens can be developed in which the processor need take only a secondary role. With the proper software, the CTM-05 can be invaluable for generating control timing pulses to trigger experimental equipment and for timing experimental processes. In addition event timing can easily be accomplished by using an event to cause the count to be stored in the counter's hold register. With the CTM-05's flexibility some thought has to go into planning the software, but that planning can pay off with simpler software and more flexible hardware in the long run.
