Sample Clocked Buffered Pulse Measurement

A sample clocked buffered pulse measurement is similar to single pulse measurement, but a buffered pulse measurement takes measurements over multiple pulses correlated to a sample clock.

The counter performs a pulse measurement on the Gate. On each sample clock edge, the counter stores the high and low ticks in the FIFO of the last pulse to complete. The sampled values will be transferred to host memory using a high-speed data stream.

The figure below shows an example of a sample clocked buffered pulse measurement.

Note If a pulse does not occur between sample clocks, an overrun error occurs.
