DDS Function Generator
Model: ATFXXD

DDS Function Generator
Brand:GRATTEN

• Direct Digital Synthesis(DDS) technology, 2 independent output channels
• 3.5-inch TFT LCD display
• 32 kinds of standard or build-in fixed waveforms
• Minimum stable output waveform: 1mV(50)

Product Description
ATFXXD Series Function generator uses Direct Digital Synthesis (DDS) technology. Its outstanding performance and system features make it a perfect solution for your testing requirement. The simplified and optimized design of the front panel and dual-language (English/Chinese) TFT display interface make your testing much easier for operation and observation. Additionally, the extendable optional functions can also improve your system characteristics.
