About This Product

■Product overview

The DG645 digital delay pulse generator is a new generation of delay and pulse generator for trigger signal sources. This is the successor model to the DG535 model, which has been a best seller for over 20 years since its release. It offers lower jitter, faster rise (1 ns), and higher repetition rate (up to 10 MHz) than the DG535, making it suitable for future demanding timing control applications. Equipped with 4 variable pulse output ports as standard, 8 delay outputs (5V or 30V output) and combination output (OR output) are also available as options. The reference signal source, which is the core of the device, can be optionally selected from oven crystal (OCXO) or rubidium time base (Rb, PRS10 type module).

■Features

・4 systems variable pulse output ・8 delay outputs (optional) ・Ultra low jitter less than 25 ps ・Maximum trigger rate 8.5 MHz ・With prescaler installed, frequency division output is possible. ・High-speed rise/fall 1 ns ・Oven ​​crystal, Rb oscillator (optional) ・Ethernet, GPIB, RS232 interface

■Applications

・Signal source for timing control ・Trigger signal source for various pulse lasers

■You can easily check the divided output

Since the trigger prescaler is installed as standard in the main body of DG645, there is no need to prepare separately and you can check the divided output immediately. It is also possible to synchronize the 10Hz beam of a high repetition rate laser and a YAG laser. The division ratio can be set for each channel.
