Pulse Width
The Pulse Width function will measure the width of an applied event from its rise to its fall (effectively one
half the period). The Base Address of the card is required as input to the function. The signal should be
applied to the CLOCK IN pin of the card. Software latency will be affected by the operating system and
will set a limit on the precision of the measurement.
