1.Introduction
ISDS205 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-T and XY alternating pattern of two-channel virtual
oscilloscope, spectrum analyzer, data recorder.
205C and 205X support logic analyzer. Logic analyzer support our Logic
software and Saleae Logic 2 kinds of software, Saleae Logic supports SPI, IIC, UART,
etc. 17 kinds protocol analysis.
205B and 205X support DDS function. DDS support 5 kinds of waveform output,
Sine wave can output up to 20M.
