Description

technical field [0001] The invention belongs to the field of electronic technology, in particular to a programmable delay trigger pulse synchronization device. Background technique [0002] In complex large-scale physical implementations or complex instrument systems, there are generally multiple instruments of different types or different individuals of the same type of instruments that need to coordinate their work. The station is delayed for a period of time to work, so it is necessary to trigger the synchronous machine to give synchronous signals respectively, so that these numerous instruments can be coordinated to form an instrument system. [0003] see figure 1 As shown, the existing trigger pulse synchronization technology is realized by combining a 1:N fan-out chip with a discrete delay-adjustable chip, where N is a positive integer, and multi-level cascading of 1:N fan-out is used to realize the expansion of multi-channel signals . This kind of trigger pulse syn...
