详细内容
the newly released model 565 digital delay pulse generator and 505 pulse generator provide 2, 4 or 8 delay and width outputs capable of synchronizing to either external or internal triggers. the model 565 digital delay pulse generator features delay and width resolution of 500 ps. the model 505 pulse generator offers delay and width resolution of 100 ns.
channels for the model 565 digital delay pulse generator and 505 pulse generator can be se-lectively gated, enabled or disabled with each channel delivering se-lectable output polarities and an independently adjustable level. these models also allow the se-lection of a reference to which each channel is synchronized. for example, any channel can be synchronized to an external trigger (to), internal trigger (also to) or the leading edge of any other channel (t1 thru tn). the channels operate in modes independent of the other channels. mode availability includes gated, enabled, burst, single shot, normal, duty cycle (divide by n).
the model 565 digital delay generator or model 505 pulse generator also operate in triggering modes common to all channels. a continuous mode provides pulse periods with 500 ps and 100 ns resolution, for the 565 digital delay generator and 505 pulse generator respectively. this allows orders-of-magnitude finer control of the triggering interval than with a frequency controller. a single-shot mode produces a single pulse with each pushbutton or each external trigger. a burst mode produces a burst of pulses se-lectable from 1 to a million. the duty cycle mode provides m pulses on and n pulses off (divide by n, if you want). both models provide the ability to store several complete setups into memory for future recall. the model 565 digital delay generator supports rs232, gpib, ethernet and usb programming. the 505 pulse generator supports rs232 and gpib. the 565 has 3 output se-lections; the 505 offers one. standard with the model 565 digital delay generator are a fast logic output, an adjustable level up to 12 v, and an optional 35 v. the model 505 pulse generator offers an adjustable level up to 20 v.
