ABSTRACT:
A trigger holdoff system for an oscilloscope is provided in which a desired trigger signal is taken out from a repetitive group of raw trigger signals with variable time therebetween. A trigger generator generates raw triggers which clock a divide by N counter programmable by a microprocessor. When the counter reaches its terminal count, a trigger is passed on to sweep or acquisition circuits from the trigger holdoff system and an enable signal is set so that the next raw trigger reloads the counter.
