In pulse measurements, the counter measures both the high and low time of a pulse on a signal after the counter is armed. A pulse is defined in terms of its high and low time, high and low ticks or frequency and duty cycle. This is similar to the pulse-width measurement, except that the inactive pulse is measured as well.

You can route an internal or external periodic clock signal (with a known period) to the counter timebase. The counter counts the number of rising (or falling) edges occurring on the counter timebase between two edges of the signal-to-measure.

You can calculate the high and low time of the signal-to-measure by multiplying the period of the counter timebase by the number of edges returned by the counter.

The pulse measurement supports the following read options:

  • Single Pulse Measurement
  • Implicit Buffered Pulse Measurement
  • Sample Clocked Buffered Pulse Measurement
