The Model 686 arbitrary waveform generator samples at up to 20 GS/s with 14-bit vertical resolution and up to 9 Gpts of waveform memory. Choose two or four analog channels, plus up to 32 synchronized digital channels at 10 Gb/s each. A 16,384-entry sequencer builds complex scenarios, and three modes cover function generation, true arbitrary playback and optional pulse patterns. Applications include radar and EW emulation, quantum control, photonics, laser diode driving and semiconductor test.
