  • Sale
  • Regular price $95.00

The ISDS205B oscilloscope features bandwidth of 16M, 48M sampling rate, 2 channels, alternating support X, Y and XY alternating pattern, spectrum analyzer, data recorder, and has a 1KHz reference square wave output interface. It supports DDS signal source and scanner functions. The DDS has 5 kinds of waveform output and the sine wave can output up to 20M.

The oscilloscope is a portable size, lightweight, and easy to carry. It uses standard BNC connectors for use with the two included 1X/10X probes. The included USB cable is both for data and power. A digital copy of the user manual and the Multi VirAnalyzer software for Windows is included on the mini CD (also available online). Once connected your computer, the signal can be viewed on your monitor for clear measurement. The software provides an intuitive interface for operation of the oscilloscope panel.
