Features:
ISDS205B 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.
Support Win
XP,Win7(32)、Win7(64)、Win8(32)、Win8(64)、Win10(32)、Win10(64)
