MDSO 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 and data recorder.

Powerful analysis function :

• Support any multi-screen display, Easy to Variety of analysis;
• Support the input waveform interpolation;
• Support the input waveform, “add”, “subtraction” and “multiplication” synthesis;
• Support the input waveform plusRectangle, bartlett, triangular, cosine, hanning, bartlett_hanning, hamming, blackman, blackman_Harris, tukey, Nuttall, FlatTop, Bohman, Parzen, Lanczos, kaiser, gauss, dolph_chebyshev18 kind of window;
• Support the input waveform filtering and design filter;
• Support the input waveform, “Lissajous”, “Frequency”, “phase-frequency”, “logarithmic amplitude-frequency”, “self-power spectrum,” “logarithmic self-power spectrum,” “auto-correlation” and “cross-correlation “analysis;
• Support under logarithmic coordinate system, the input waveform, “Frequency”, “phase-frequency”, “logarithmic amplitude-frequency”, “self-power spectrum,” “logarithmic self-power spectrum,” “self-related” and “mutual related “analysis.

Powerful data recorder function:

• Support continuous data collection and storage, and can move, zoom, view global data, and compare multiple data collection
• High-speed USB2.0 for fast transfer, unlimited long the collected data, records into files for easy viewing and analysis of collected data
• 24M of continuous recording up to meet the capture function of the general agreement, such as SPI, IIC, UART, etc.

Oscilloscope features:

• Bandwidth 20M
• Sample 48M
• the number of channels: 2
• Input voltage range [-50V,+50V](With probeX10)
• Memory depth 1M*2
• AD Bit 8
• Software triggerrising, falling, rising / falling, differential, rising / falling+differential
