TFG3500 Series DDS Waveform Generator

The TFG3500 series are function generators with maximum frequency of 10MHz, 20MHz, 40MHz and 60MHz, based on Direct Digital Synthesis (DDS) technology providing flexible performance and system features for basic scientific and industrial requirements.The10 bits resolution, 180MSa/s sampling rate, 16k pts memory length, and 32 built-in waveforms create various waveforms for different needs. Free PC software for USB and RS-232 interfaces control. The TFG3500 series have additional functions of multiple modulations FM, AM, FSK, ASK and PSK, 200MHz external frequency counter, 40 sets memories and multiple protections. Stable output frequency, high accuracy and low distortion make TFG3500 an ideal solution for an accurate and affordable signal source for industrial, scientific research and educational applications.
