A s a p ul se gener ator model 505 provides rate, delay, width, and output ad j ust ab i l i t y wi t h each channel . As a digital delay generator, model 505 provides fine resolution, timing, and low jitter. By allowing exter nal, inter nal, and 3rd party software to control the 505 this Digital Delay and Pulse Gene rator can address many application specific requirements. The outputs are synchronized to one another with coherence of 5 ns. A channel’s ti ming can be referenced to any other channel or to the zero delay point (To) The edges are adjustable in 100 ns steps. C hannel s can b e sel ect i vel y gat ed, enabled / d i sab l ed . Each channel p ossesses separ ate output l evel and p ol ari t y charact eri st i cs along with system level gating capability. Model 505 provides the ability to store custom parameter settings which are able to be recalled for later use.
