Stanford DS340 15MHz Function Generator

The DS340 is a 15MHz function and arbitrary waveform generator from Stanford Research Systems 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.

• 1μHz to 15.1MHz frequency range
• 1μHz frequency resolution
• Sine, square, ramp, triangle and noise
• Phase continuous frequency sweeps
• 16,300 point arbitrary waveforms
• FSK modulation
• Optional RS232 and GPIB interfaces

Sine waves and square waves can be generated at frequencies up to 15.1MHz, and ramps and triangles up to 100kHz. Frequency resolution is 1μHz for all functions. The DS340 also includes a 10MHz 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 synchronisation 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. PC software is provided for composing, editing and downloading arbitrary waveforms. The waveform memory can be placed back at rates up to 40 Msamples/s.

Both internal and external FSK modes allow the output frequency to be rapidly toggled between two preset values. FSK toggling can be done internally (at rates up to 50kHz), or externally via a rear-panel input.

Arbitrary Waveform Composer (AWC) software is provided at no charge. AWC is a simple, menu-based program which lets you create and edit arbitrary waveforms on the screen, store them and download them to the DS340.
