Description

Overview

GAOTek dual channel digital signal generator is a multi-functional signal generator with high precision and high performance. It adopts large scale of FPGA integrated circuits, high-speed MCU microprocessor and with high precision oscillator as base in the inner circuit, which make the signals more stable. SMT process can greatly improve the anti-interference and lifetime of the instrument. It has entirely independent dual-channel DDS signal and TTL level output, can generate signals of sine or triangle or square or sawtooth or pulse wave, white noise, etc. This instrument is of great advantage in generating signal, scanning waveform, measuring parameters, etc. It’s an ideal testing or measuring instrument for electronics engineer, electronic laboratory, teaching and researching.
