Delay generator SY4000

digitallaboratory

The SY4000 is a digital delay generator designed to create up to 8 delayed output pulse sequences precisely synchronized with an internal or external clock. It is mainly used for synchronization and control of laser components such as AOM drivers, Pockels cell drivers, laser diode drivers, flash lamp drivers, photodetectors, and data acquisition systems. Both encased and OEM versions are available, with the encased version suitable for laboratory use and the OEM version ideal for integration. The device offers multiple communication options including RS232, USB, LAN, WLAN, and CAN, and comes with user-friendly configuration software and internal power supply.

Features

• 8 independent output channels
• Ultra-stable internal clock 0.2 ppm
• Precise delay/pulse width control in range 2 ns to 150 ms
• 25 ps timing resolution
• High-accuracy synchronization (locking) to external pulse train
• Jitter < 30 ps
• DAC/AWG output
• Both 50 Ω (6 outs) and differential (8 outs) outputs present
• Frequency divider / Burst (software and hardware triggered) / Gating / Single shot
• Communications: OEM version – CAN BUS; Encased version – LAN, WIFI (optional), RS232, USB (VCP) – via REST API or DLL’s

Applications

• Mode locked and Q-switched fs, ps & ns lasers
• Triggering of a data acquisition system
• General purpose pulse generator
• Precise system clock source
• Laser pulse train conversion into a clean clock source
• All functions above at once

Highlight functions

• Locking to an external clock source (e.g., photo-diode pulse train) for phase-locked triggering
• Trigger rate control and limiter circuit to protect laser components
• Single ended and differential outputs
• Instant switch between two configurations in delay blocks, controlled by burst counter, gate input, frequency divider, or software commands
• Low jitter sync pulse output for high-speed acquisition systems (e.g., streak camera triggering), typical jitter 3–5 ps
• Software-controllable multiplexer for monitoring output signals
• Clock output: 1:1, 1:2 frequency
• Up to 4 pulse outputs can be combined using OR, AND, NOT logic
• DAC output for controlling devices such as AOM pass through
