Input Triggering with Burst Mode and CLC

After triggering, each external clocking pulse initiates capture of a sample for every channel using the internal clock. Software control shuts down the sampling process when a sufficient number of samples has been collected. Sampling does not resume until enabled by the next triggering signal.

A DAPserver can be the answer for rugged testing environments. Destructive tests often use hardware triggering to initiate data collection. The same signal that releases the test also activates sampling.

Notes:

  1. Trigger is active high, held for at least tTrigMin
  2. All clock levels must be held for at least tExtClkPW
  3. Clocking activity begins tTCsetup after triggering goes active
  4. Switch to internal clock, synchronize after tSynch
  5. Sample until every channel in the channel list gets a value
  6. Resume sampling activity with each external clock pulse
  7. Software control ends burst after the data set is collected
  8. Digitized values issued after conversion delay
  9. No further sampling activity until the next triggering pulse
