Produces precisely spaced output pulses suitable for calibrating CRO time bases. Can be programmed in binary by using 2240 for A, or in BCD by using 2250.Use crystal oscillator or other high-accuracy source for external clock, Time interval of output pulse is equal to clock width multiplied by n + 1, where n is number programmed into A, (1 to 255 for 2240 and 1 to 99 for 2250). Circuit can be programmed electronically by microprocessor if desired.-W. G. Jung, IC Timer Cookbook, Howard W. Sams, Indianapolis, IN, 1977, p218-220.
