PC USB 2CH 20M Digital Oscilloscope + Spectrum Analyzer + DDS Generator + Sweep
 

The dual-channel digital oscilloscope, with "low-cost, high-performance" as the design goals. well-designed bandwidth of 20M, 48M sampling rate, 2 channels, alternating support X, Y and XY alternating pattern of two-channel virtual oscilloscope, spectrum analyzer, data recorder. Meanwhile, it support DDS and Sweep function. DDS support 5 kinds of waveform output, Sine wave can output up to 20M. The device communicate with the PC via high speed USB2.0.
