Dual-channel function signal generator from this series 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/triangle/square/sawtooth/pulse wave, white noise, etc. This instrument is of perfect combination for high usability, excellent technical parameters and multiple functions in generating signal, scanning waveform, measuring parameters and use aspects. It's a great testing or measuring instrument for electronics engineers, electronic laboratory, teaching and researching.
