High Precision Digital Dual Channel DDS Function Signal Generator Sine/Square Waveform Frequency Meter Counter 12MHz

High Precision Digital Dual Channel DDS Function Signal Generator Sine/Square Waveform Frequency Meter Counter 12MHz

The Dual Channel Function Signal Generator from this series is a multi-functional signal generator(also a counter and frequency meter) with high precision and high performance. It adopts large scale of FPGA integrated circuits, high-speed MCU microprocessor and SMT in the inner circuit, which 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, step wave, 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.  

Features: 
Adopts DDS direct digital synthesis technology, can generate precise, stable output signals with higher distortion. 
With independent channel indicators and channel operation keys, LCD 1602 display, more convenient for the operation. 
Completely independent dual-channel output, can work in sync, phase difference is adjustable. 
High frequency resolution: total range frequency resolution is 10mHz. 
The duty ratio of each channel can be adjusted independently. 
DC offset adjustment range is -10V to 10V, the resolution is 0.1V.
