Features: FY-Economic series DDS function /Arbitrary waveform generator using direct digital synthesis(DDS) technology, FPGA design Inside14 commonly used waveforms for prefabrication Low distortion with 1 watt power output,broadband frequency measurement and Counter and other functions. The three downloadable 256 arbitrary waveform memory. The prefabricated 14 kinds of waveform, users can customize the waveform. The highly precision of the output waveform waveform calculated by the function of waveform synthesis, highly precision, small distortion. The Waveforms are sine, square wave, triangled wave, saw tooth wave,User defined waveform (arbitrary waveform), commonly used pulse, noise,ECG waveform. LCD1602 liquid crystal display English, direct digital set continuous adjustment knob.
