GENERAL INFORMATION
GENERAL INFORMATION
The GD150/N Delay and Gate Module (Fig. 1) provides delay and gate signals for on-off (timing) control of certain modules of the M100 Modular Counting System. The GD150/N contains two identical timers that control the delay and the width of the output signal. The timing cycle may be started either by a NIM-standard fast logic signal or by a NIM- standard signal for transmission for Digital Data.
The width of the output signals is adjustable between 100 nSec to 110 uSec.
