ORTEC 462

Time calibrator

Calibrates time-to-amplitude converters with start and stop signals separated by multiples of a selected period, with adjustable repetition rate.

Selectable calibration periods: 10, 20, 40, 80, 160, 320, 640 ns; 1.28, 2.56, 5.12, 10.24 µs1
Calibration range: 80 ns–81.92 µs1
Absolute accuracy, 10 ns period: ±10 ps1
Accuracy, other periods: ±0.005% of total period (all other period selections)1
