The Model 765 Fast Rise Time Pulse Generator offers 500 MHz frequency, 70 ps rise and fall times and adjustable pulse widths.

The flexible pulser allows programmable amplitudes and offsets ( + / - 5V) and progammable widths down to 300 picosecond. Delay and Pulse Width resolution is 10ps and jitter is <25ps. The gesture-ready touchscreen GUI allows users to quickly set up 4 channels of output. Conventional push-buttons and a rotary encorder offer additional programming simplicty. We have made signficant 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.  

Min Pulse Width and Resolution

The pulse width can be adjusted from 300 ps to 8 s with a resolution of 10 ps responding to the needs of the most different applications.

Time Resolution

The delay resolution is 10 ps allowing a very fine adjustment between the trigger in signal and the generated pulses.

Jitter is an important characteristic of the pulse quality, and low jitter in a clock waveform is an important feature in reducing error in communications systems.

The low jitter below 25 ps allows a perfect synchronization among channels and among multiple pulses of the same channel.

  • Continuous: in continuous mode, the output channel supplies the pulses configuration at a repetition rate up to 125 MHz;
  • Single: in single mode, the output channel waits for the trigger signal then it generates the pulses configuration only once;
  • Burst: in burst mode, for each trigger received, the output channel repeats the pulses configuration a programmed number of times between 1 and 4294967295;
  • Gated: in gated mode, the output channel supplies the pulse configuration only when the trigger is “true”, if the trigger becomes “false”, it continues the generation until the end of the pulses then it stops.

External Width (square / amplify external pulse)

The external width operation mode transmits the Trigger Input signal to the output channel. This feature allows to make edges stepper than those of the source taking advantage of the RIDER Fast Edge technology. Furthermore it can be used to amplify / reduce the amplitude, invert, apply an offset to the source pulses or to generate a particular pulse pattern sequence.

Skew between Channels

Every pulse can be delayed up to 1 s with a resolution of 10ps from trigger signal by setting the channel delay and the pulse delay parameters, the total delay of a pulse is:
output N delay + pulse P delay + fixed delay.

This skill allows to produce an accurate skew to synchronize other test equipment compensating instrumentation skew, or to test the response of a digital asynchronous system at the arrival of not synchronized pulses.

Single Ended / Differential

By using one channel as opposite of the other, it is possible to obtain the differential operation mode.

Model 765 Touch User Interface

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.

Pulse Combination

( quadruple mode pulse)

Using the multiple pulse combination to generate quadruple pulses, it is possible to reach an output signal frequency of 500 MHz that can be used to supply a clock.
