Introduction
|
|
The TFG3500A series are arbitrary waveform/function generators with maximum frequency of 10MHz, 20MHz and 40MHz. The TFG3500A series are based on DDS (Direct Digital Synthesis) 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. A free PC software for USB and RS232 interfaces control, multiple modulations (AM, FM, FSK, ASK), 40 sets memories and multiple-protection designs make TFG3500A series an ideal solution for an accurate and affordable signal source for industrial, scientific research and educational applications. |
