The TFG3500 series are function generators with maximum frequency of 10MHz, 20MHz, 40MHz and 60MHz. The TFG3200 series are LOW-COST function generators with exactly same specifications as TFG3500 series. The TFG3500 and TFG3200 series are based on DDS (Direct Digital Synthesis) technology providing flexible performance and system features for basic scientific and industrial requirements. The10 bits resolution, 180MSa/s sampling rate, 16k pts memory length, 32 built-in waveforms create various waveforms for different needs. A free PC software for USB and RS232 interfaces for system control. The TFG3500 series have additional functions of multiple modulations (AM, FM, FSK, ASK), 200MHz external counter, 40 sets memories and multiple protections. Stable output frequency, high accuracy and low distortion make TFG3500 and TFG3200 series an ideal solution for an accurate and affordable signal source for industrial, scientific research and educational applications. |
