DDSO-100/HDSO-100 dual-channel digital oscilloscope, with "low-cost,
high-performance" as the design goals. well-designed bandwidth of 40M, 100M
sampling rate, 2 channels, alternating support X, Y and XY alternating pattern of
two-channel virtual oscilloscope, spectrum analyzer . Meanwhile, DDSO-100 device
has a the DDS function, supports five kinds of waveform output. Sine wave can
output up to 20M. The device communicate with the PC via high speed USB2.0.
