1Overview
The Berkeley Nucleonics Model 685C is a high-performance arbitrary waveform generator built for laboratories and production lines that need both speed and signal fidelity from one instrument. Sample rate can be programmed from 1 S/s to 3 GS/s, with 16-bit vertical resolution throughout, ensuring exceptional signal integrity. Rise and fall time is 320 ps.
The platform scales with the channel count. It is available with 2, 4, or 8 analog channels, each backed by deep arbitrary waveform memory of up to 4 Gpts per channel. Optional digital channels, up to 32 in total, run in synchronous with analog generation, so a single unit can drive both the analog and digital sides of a mixed-signal design.
Two operating modes cover the span of waveform work. Simple Rider AFG provides a direct digital synthesis function generator, and Simple Rider True Arb gives variable-clock arbitrary generation with synchronized digital pattern output in DPG mode. A 7-inch capacitive touchscreen, front-panel buttons, and a control knob make local operation fast, while LAN, USB-TMC, and GPIB support full remote automation.

4User Interface
Simple Rider AFG: Function Generator Mode
The Simple Rider AFG user interface is designed using a touchscreen interface; it has been developed to put all the capabilities of modern waveform generators right at your fingertips. All instrument controls and parameters are accessible through an intuitive UI that recalls the simplicity of modern tablets and smartphones. Swipe gestures give easy access to the output waveform parameters, a touch-friendly virtual numeric keypad improves data entry, and time-saving shortcuts and intuitive icons simplify instrument setup.
Simple Rider True Arb: AWG and DPG Mode
In the Simple Rider True Arb interface, users can define complex waveforms with up to 16,384 sequence entries of analog waveforms and digital patterns, and define their execution flow by means of loops, jumps, and conditional branches. Digital output combined and synchronized with analog output signals is an ideal tool to troubleshoot and validate digital designs.
The waveform memory length of up to 4 GSamples per channel, combined with up to 16,384 sequence entries and up to 4,294,967,294 repetitions, makes the Model 685C suited to the most demanding technical applications. Up to 4 instruments can be synchronized together to obtain a 32 analog, 128 digital channel generator, and a dedicated synchronization bus guarantees intra-chassis synchronization. The Model 685C supports the standard Ethernet interface for remote control and easy customized instrument programming.
