Model 686 — Arbitrary Waveform Generators, 20 GS/s AWG

20 GS/s and still 14-bit. No trade-off.

A 14-bit arbitrary waveform generator with sample rates from 1 S/s to 20 GS/s, up to 9 Gpts of memory, and three operating modes — AFG, True Arb, and an optional Pulse Pattern Generator — across 2 or 4 fully synchronized analog channels plus up to 32 digital channels.

One model line, several configurations.

Same platform, sized to your channel count and application.

Model 686-2C-SE

2-channel, single-ended

Model 686-2C-SE

Two 5 Vpp single-ended analog channels at 20 GS/s — the baseline configuration for most bench and lab setups.

Models
686-2C-SE
Model 686-2CD

2-channel, differential

Model 686-2CD

Two differential channels (2.5 Vpp, or 1.25 Vpp single-ended) at the same 20 GS/s, for applications that need a true differential drive.

Models
686-2CD

4-channel

Model 686-4C-SE / 686-4CD

Four analog channels in single-ended or differential output, plus up to 32 synchronized digital channels and the optional Pulse Pattern Generator.

Specifications reproduced from the Model 686 datasheet (V1, 2024-04), as published at berkeleynucleonics.com. Photo shown is the 2-channel configuration (CH1/CH2, MOD1/MOD2 visible on the rear panel).

Where the 686 goes to work.

Optics, photonics, and RF wireless
driving electro-optic modulators and pulsed laser diodes, and building complex RF/IF/IQ waveforms.

Quantum applications
generating QKD and quantum-sensing signals, multi-level PAM and PRBS patterns, across up to 16 synchronized analog channels when four units are linked.

Semiconductor test
high-speed serial testing and characterization with the optional Pulse Pattern Generator, up to 6.5 Gbaud.

Aerospace and defense
radar, lidar, and sonar RF-modulated signal emulation, and electronic warfare scenario generation.

Generate the real signal, not an approximation of it.
