Introduction
|
|
The TFG3500E series are function generators with maximum frequency of 5MHz, 10MHz, 15MHz and 20MHz. TFG3200E series are LOW-COST function generator with exactly same specifications as TFG3500E series. The TFG3500E and TFG3200E series are based on DDS (Direct Digital Synthesis) 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. A free PC software for RS232 interface control for system control. The TFG3500E and TFG3200E series have additional functions of multiple modulations (FM, FSK, ASK), 200MHz external counter, 40 sets memories and multiple protections. Stable output frequency, high accuracy and low distortion make TFG3500E and TFG3200E series an ideal solution for an accurate and affordable signal source for industrial, scientific research and educational applications. |
