Model 765 | 800 MHz Fast Rise Time Pulse Generator
The Model 765 Fast Rise Time Pulse Generator offers up to 800 MHz pulse frequency and 70 ps rise and fall times. The Model 765 has programmable pulse amplitudes and baseline offsets, and programmable widths down to 300 picoseconds. Delay and Pulse Width resolution is 10 ps with a jitter of <25 ps. The gesture-ready touchscreen GUI allows users to quickly set up 4 channels of output. The conventional push-buttons and a rotary encoder offer additional programming simplicity. We have made significant improvements in our analog front end as well, ensuring minimal overshoot and ringing. That's just the beginning... the Model 765's innovative hardware architecture provides advanced pulse sequences, such as double pulse or quad pulse, with fully independent timing parameters. Give us a call, we are happy to discuss your requirements.

USER INTERFACE AND PULSE OUTPUT
The Model 765 user interface is designed for touch and it has been developed to put all the capabilities of the modern Pulse and Waveform Generators right at your fingertips.
All instrument controls and parameters are accessed through an intuitive UI that recalls the simplicity of Tablets and modern smartphones: touch features and gestures are available to engineers and scientists to create single or multiple pulses (dual, triple and quadruple pulse mode) in few touches.
