Model 750 | 50 MHz Pulse/Delay Generator

The BNC Model 750 50 MHz Pulse & Delay Generator in the micro package provides 4 (or 8 in option) independent delayed pulses. Delays up to 10 seconds can be programmed with 100 ps resolution and channel-to-channel jitter less than 50 ps RMS. SMB outputs deliver adjustable 1.5 V to 5 V into 50 Ω ( or 3V to 10V into Hi-Z), 1 ns rise time. Pulse amplitude, polarity, and pulse width are independently adjustable on each output channel. Model 750 also offers two inputs or three internal synchronized Timers (adjustable from 0.1 Hz to 50 MHz) or software commands for triggering all selected delay channels. Either trigger rate may be set as one-shot or repetitive.

The generator has an internal 100 MHz TCXO clock reference and also accepts an external clock reference from 10 MHz to 240 MHz sine or square wave. Model 750 can be remotely controlled via USB or Ethernet (LAN). This pulse generator is well suited to synchronize all the devices of the Picosecond Laser System (PLS). In this application, the “clock input” of the delay generator receives a reference signal (80 MHz for example) from a laser oscillator via an O/E (optical-to-electrical converter) and the delay generator provides single or repetitive pulses (adjusted in delay, amplitude, polarity, and pulse width) synchronized on “clock input” with very low jitter. From delay generator 4 GPIO under software control allow the command to the low-frequency device of the Laser System for security or control.
