Implicit Buffered Two-Signal Edge-Separation Measurement

    Last Modified: February 26, 2018

    Implicit buffered and single two-signal edge-separation measurements are similar, but implicit buffered measurement measures multiple intervals.

    The counter counts the number of rising (or falling) edges on the Source input occurring between an active edge of the Gate signal and an active edge of the Aux signal. The counter then stores the count in the FIFO. On the next active edge of the Gate signal, the counter begins another measurement. The sampled values will be transferred to host memory using a high-speed data stream.

    The following figure shows an example of an implicit buffered two-signal edge-separation measurement.
