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 smart phones: 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.
Downloadable resources such as datasheets, firmware, software, drivers and products manuals. Alternatively, you can browse resources directly by visiting our downloads page.
