DS340 Function/Arb Generator
· 1 µHz to 15.1 MHz frequency range
· 1 µHz frequency resolution
· Sine, square, ramp, triangle & noise

The 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 µHz 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. PC software is provided for composing,
editing and downloading arbitrary waveforms. The waveform
memory can be played 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 50 kHz),
or externally via a rear-panel input.
