SY4000
Digital delay generator
The digital delay generator SY4000 is designed to create up to 8 delayed output pulse sequences precisely synchronized with the internal or external clock. Digital delay generators can provide precise delays for triggering, syncing, delaying, and gating events.
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
- Hi-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 (typically photo-diode pulse train). Triggering system is locked to the laser oscillator and trigger time is always in phase with the optical pulse.
- Trigger rate control and limiter circuit. It helps to protect laser components from damage due to exceedingly high/low triggering rates.
- Single ended and differential outputs.
- Instant switch between two configurations in delay blocks. Burst counter, gate input, frequency divider or software commands may serve as the configuration switching signal sources. Configuration switch is used to control optical pulse pickers (EO or AOM) in a highly flexible manner.
- Low jitter sync pulse output used for high-speed acquisition systems like streak camera triggering. Typical jitter is 3…5 ps with the respect to the optical pulse.
- Control connector.
- Software-controllable multiplexer may divert any of the output signals to this connector to monitor what is on other connectors without disturbing them.
- Clock output: 1:1, 1:2 frequency.
- Up to 4 pulse outputs can be combined to single signals by OR, AND, NOT logical operations.
- DAC output, controlling, e.g. AOM pass though.
Description
The Ekspla’s digital delay generator SY4000 is designed to create up to 8 delayed output pulse sequences precisely synchronized with the internal or external clock. Digital delay generators can provide precise delays for triggering, syncing, delaying, and gating events.
Our SY4000 digital delay generator is mainly employed for synchronization and control of different laser components: AOM drivers, Pockels cell drivers, laser diode drivers, flash lamp drivers, photodetectors, data acquisition systems, etc.
Ekspla can provide both encased and OEM versions of SY4000 digital delay generator. The encased digital delay generator version can be controlled via RS232, USB, LAN, WLAN and also contains a user-friendly configuration software as well as an internal power supply. These communication options as well as software are also available in SY4000 digital delay generator’s OEM version and can be reached by adding additional Ekspla’s OEM communication board upon customer’s request. The encased digital delay generator is an optimal solution for laboratory use while SY4000 OEM version is ideal for integration and is frequently paired with an additional Ekspla’s OEM communication board.
