Product No : TFG3500A_Series
Product Description

The TFG3500A series are arbitrary waveform/function generators with maximum frequency of 10MHz, 20MHz and 40MHz, based on Direct Digital Synthesis (DDS) technology providing outstanding performance and system features for basic scientific and industrial requirements.

The 10 bits resolution, 180MSa/s sampling rate, 16k pts memory length, 32 built-in waveforms and 8 user-defined arbitrary waveforms create various waveforms for different needs. Free PC software for USB and RS-232 interfaces control. The TFG3500A series have additional functions of multiple modulations FM, AM, FSK and PSK, 200MHz external frequency counter, 40 sets memories and multiple protections. Stable output frequency, high accuracy and low distortion make TFG3500A series an ideal solution for an accurate and affordable signal source for industrial, scientific research and educational applications.
