Synchronization Module

Pulse Delay Generator DG-3O1I-17 With touch screen and USB

The DG-3O1I-17 Delay Generator (Synchronization Module) has Three TTL output channels and one Input Chanel. Each output is configurable in terms of the delay, relative to one edge of the input pulse. The duration of the pulse or pulse width and the type of output logic (positive or negative), are also configurable. The high speed and synchronism of this equipment, is due to the use of a FPGA device and a oscillator of high precision.

The touch screen start menu has an area that serves to put the logo and some text of the client or his laboratory; consult the user manual for more information on the size of the image to customize the product.

Delay Range: 0.1 us - 6553.5 us.
Delay resolution: 0.1 us.
Pulse width Range: 0 us - 65535 us.
Pulse width resolution: 1 us.

In a typical application of Laser Control for Spectroscopy, the outputs can be used as follows:
Output A: Flash Lamp Trigger
Output B: Optical Spectrometer-Trigger
Output C: Electro-Optic Q-Switch Trigger
