24-channel controlled pulse generator for light-emitting diodes, which has a speed of response of 80 MHz. [For calibrating scintillation and Cherenkov counters]

A 24-channel starting-pulse generator for fast light-emitting diodes for monitoring scintillation and Cherenkov counters is described, which ensures a maximum repetition frequency of 8 MHz. The generator has digital control of each channel, as well as common turn-on and turn-off with the CAMAC main.
