  • The Pulse Power Sensor can measure 4 states within a single pulse.
  • Depending on the rep rate, the minimum state width is approximately 1% of the pulse rep rate period.
  • Depending on the rep rate, the maximum state width is approximately 99% of the pulse rep rate period.
  • For applications with rep rates near the low or high extremes of the spec, consult the user manual for the exact limits.
