Model 577 Digital Delay/ Pulse Generator


Product Details

The Model 577 provides multi-channel 250 ps-resolution timing, delaying, gating, pulsing and syncing functions.. There are many practical modes of operation and features in addition to the traditional digital delay and pulse generator modes.


Each channel provides both delays and widths – so a 4-channel Model 577 provides the same delay and width functionality of competitive 8-channel units. The 577 is available in 4 and 8 channel configurations, with optional Ethernet, High Voltage and Dual Input Trigger options.


This Digital Delay/Pulse Generator, representing our finest in precision timing, provides precise delays and widths with 250pS resolution for times up to 1000 seconds. Low jitter both with internal clocks (50pS) and using an external trigger (800pS) give users the timing needed to control many devices. This is particularly useful where several pulses or gate signals need to be delayed and timed with respect to each other or the common trigger. You may even use one channel as a trigger reference for other channels, locking the timing delays when needed.


There are lots to learn about the Model 577, which offers much more than a clock-divider, independent channel triggering, independent amplitudes/channel, delay and width control, and a Labview 8 driver.
