Function Generator Model GX320

The Function Generator Model GX320 is ideal for higher education, R&D engineers and scientific research.

With its Direct Digital Synthesis (DDS), the GX320 provides much greater accuracy and frequency stability than a traditional generator. The Model GX320 can be used to generate precise, varied signals: waveforms, sine, triangle, square & LOGIC, TTL output. It is also equipped with internal and external modulation (AM, FM), as well as linear and logarithmic sweep functions. Additionally, the Shift K function allows phase or frequency skips.

With the BURST function, users can choose the number of cycles per time period. This allows even more detailed analysis, as well as the detection of very brief events. In addition, the Model GX320 can be set up in a cascade arrangement to simulate complex signals: Three-phase networks, Fourier synthesis, etc.

The Model GX320 also includes an external frequency meter ranging from 5Hz to 100MHz and is equipped with a large LCD screen (125 x 45mm) which is exceptionally easy to read. The backlighting is adjustable and the contrast can be enhanced if necessary.
