Multichannel remotely programmable logic delay system

A remotely programmable logic delay system is described consisting of up to 16 independent electronic delays for fast NIM pulses - each having a delay capability of 0-101 ns. Each delay can be set locally at the delay unit or remotely from a two-wide CAMAC unit which permits front-panel manual or computer selection of any delay channel and its delay. Individual delay settings over the full range show less than a +- 1 ns maximum accumulated error from their nominal settings for typical NIM pulse widths down to 6 ns fwhm at instantaneous rates up to 50 MHz. Pulse-width variations between input and output are less than +- 1 ns for the same pulse widths and rates. (Auth.)
