Description
MODEL 575-4C / 4-Channel Digital Delay Generator (250ps Delay & Width Resolution )
MODEL 575-4C provides multi-channel 250 ps-resolution timing, delaying, gating, pulsing and synchronizing functions for an attractive price. There are many practical modes of operation and features in addition to the traditional digital delay and pulse generator modes. For usefulness and value – there is nothing comparable.
Each channel provides both delays and widths -a 2-channel Model 575 provides the same delay and width functionality of competitive 4-channel units. The 575 is available in 2, 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 250 ps resolution for times up to 1000 seconds. Low jitter both with internal clocks (50 ps) and using an external trigger (800 ps) 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 is much to learn about the Model 575, which offers much more with a clock-divider, independent channel triggering, independent amplitudes/channel, delay and width control, and a LabVIEW 8 driver. Give us a call, we are happy to discuss your applications.

FIELD PROGRAMMABILITY
45V Rise, 50 Ohm, 10nS / Div 45V Rise Hi Z, 10nS / Div
***Due to the power consumption and heat restrictions, a maximum of four AT45 channels can be added on a single ustomer Output Modes
Custom Modules such as the TZ-50 give users an expand list of capabilities with the Model 575. One example is our TZ-50 option, which allows customers a TTL signal into 50 ohms expanded.
Negative Delay
Use the handy negative delay feature to reference one channel with respect to another channel in positive or negative time increments. By allowing a channel to reference another channel as its trigger, you can synchronize the channels with respect to each other.Note that Negative Delay cannot trigger a channel before your initial trigger. It is intended to compliment the channel referencing option.
