| KPCI3100_PulseWdth.pdf | Measurement of Pulse Width Programming a counter for gated event counting performs pulse width measurement. The signal of interest is connected to the gate of the counter. The number of accumulated counts, of a known timebase, is indicative of the pulse width at the gate. Often the internal timebase of a multifunction board is too fast to allow just a single 16bit counter to be used for the gated event counting. For example, the multifunction boards of the KPCI3100 driver (KPCI-3101, KPCI-3102, etc.) have an internal timebase of 20MHz. A single 16bit counter will reach full scale in 3.27 msec. Gated Event Counting, counts pulses of the timebase but only when the signal of interest is at logic 1 state. If the pulse of interest is longer than 3 msec in duration, then additional counters must be used to perform the task. One approach is to use a counter in square wave generation mode to provide a slower timebase signal to the gated event- counting channel | |
