The DG645 digital delay/pulse generator is a highly flexible design capable of providing accurate pulses at rates up to 10 MHz. Compared to it’s predecessors the DG645 features a much lower jitter, higher accuracy, faster trigger rates, more outputs and is capable of remote control via Ethernet, GPIB and RS-232 communication interfaces. .DG645数字延/冲发生器是一种够在率10兆提供精确的冲度灵活的。相比它的前DG645特征更低的抖动更的精度更快的发率更多的出可以太网程控制GPIB和RS-232信接口。。Typical operation of digital delay generators that includes measuring time intervals by counting fast clock cycles, can lead to errors due to a timing indeterminacy. The DG645 reduces timing indeterminacy to zero by measuring the timing of triggers according to the internal clock and making up for analog delays, resulting in a 100x reduction of jitter.典型操作的数字延发生器包括快数时周期测的时可以导由于定时不确定性差。DG645由根据内时和弥模拟延测发定时定时不确定性低到从在100X减少抖动。
