Stanford Research DS335 Synthesized Function Generator, 1 µHz to 3.1 MHz

Stanford Research DS335 Synthesized Function Generator, 1 µHz to 3.1 MHz The DS335 Function Generator is a 3 MHz function generator designed for general benchtop or ATE applications. Based on a Direct Digital Synthesis (DDS) architecture, the DS335 includes features not normally found in function generators in this price range. Basic functions include sine waves and square waves up to 3.1 MHz, and ramps and triangles (up to 10 kHz). A 3.5 MHz Gaussian white-noise generator is also provided. All functions can be swept logarithmically or linearly in a phase-continuous fashion over the entire frequency range. A rear-panel SWEEP output marks the beginning of a sweep to allow synchronization of external devices. Both unidirectional and bidirectional sweeps can be selected. Internal and external FSK modes allow the output frequency to be rapidly toggled between two preset values. Toggling is done either at a fixed, internal rate of up to 50 kHz, or externally via a rear-panel input. Outputs
