Digital delay trigger

The invention provides a digital delay trigger, comprising: a reference clock module, an interaction platform, a DPDT (double pole double throw) module, an output module and a power supply, wherein the DPDT module generates a frequency control word, a first delay control word and a second delay control word according to the frequencies and delays of each channel set by a user through the interaction platform, and generates a first pulse output signal according to the first delay control word, the frequency control word and a reference clock generated by the reference clock module; the output module outputs a second pulse output signal according to the first pulse output signal and the second delay control word. By integrating all the functional modules, the pulses with multiple paths, wide rang, low jitter, independent and adjustable delay and frequency of each path can be output, and high-precision adjustment of multi-path pulse delay is realized. Therefore, the entire system is highly integrated, cost and c
