Stanford Research Systems DS340 Overview
The Stanford Research DS340 is a 15 MHz function and arbitrary waveform generator based on Direct Digital Synthesis (DDS). A combination of features, performance and low cost make the DS340 ideal for a variety of test and measurement applications. Sine waves and square waves can be generated at frequencies up to 15.1 MHz, and ramps and triangles up to 100 kHz. Frequency resolution is 1 ToneHz for all functions. The DS340 also includes a 10 MHz Gaussian white-noise generator. All functions can be swept logarithmically or linearly in a phase-continuous fashion over the entire frequency range of the instrument. A rear-panel SWEEP output provides a trigger signal at the start of a sweep to allow synchronization of external devices. Both unidirectional and bidirectional sweeps can be selected. Up to 16,300 arbitrary waveform points can be downloaded to the DS340's waveform memory via the optional GPIB or RS-232 interfaces.
