ISDS205B 2CH Digital Oscilloscope 20M Virtual oscilloscope Spectrum Analyzer Data Recorder DDS Sweep
Introduction:
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.
