Product Description
Twintex TFG-3220E Dual Channel DDS Function Waveform Generator 20MHz
IntroductionThe TFG3200E series are LOW-COST function generators with maximum frequency of 5MHz, 10MHz, 15MHz and 20MHz, based on Direct Digital Synthesis (DDS) technology providing flexible performance and system features for basic scientific and industrial requirements.
The 8 bits resolution, 100MSa/s sampling rate, 1024 pts memory length, 32 built-in waveforms create various waveforms for different needs. Optional PC software for RS-232 interface control. The TFG3200E series have additional functions of multiple modulations FM, FSK, ASK and PSK, 200MHz external frequency counter, 40 sets memories and multiple protections. Low-cost, stable output frequency, high accuracy and low distortion make TFG3200E series an ideal solution for an accurate and affordable signal source for industrial, scientific research and educational applications.
