Arbitrary Waveform Generators

Arbitrary Waveform Generators Brief Introduction
With Direct Digital Synthesis technique (DDS), large scale integrated circuits and soft-core embedded system (SOPC), high sampling rate 500MSa/s, TFG3900A series are of the excellent technical performances and powerful function characteristics which are necessary for the fast measurement. TFT-LCD interface can show the illustration of output waveform and parameters. Keypads and knob are convenient for operation.
