DB463 Delay Box

ORTEC DB463 Delay Box
  • Aligns fast-timing channels that incorporate coincidence circuits or Time-to-Amplitude Converters (TACs)
  • Four independent sections
  • 50-Ω calibrated cable delay for linear or logic signals
  • 0 to 63.5-ns delay in 0.5-ns steps

The ORTEC Model DB463 furnishes a 50-Ω calibrated cable delay, providing relative delays from 0 to 63.5 ns with 0.5-ns increments in each of four identical sections. Longer delays may be achieved by cascading several  Model DB463 Delay Box sections.

The Model DB463 is convenient for aligning fast-timing channels that incorporate coincidence circuits or time-to-amplitude converters.
