USB Scopes Provide Huge Buffer

The PicoScope4000 USB-powered, PC oscilloscope adapters provide a 20-MHz bandwidth and are available in two- and four-channel versions. Of note, the instruments feature a 32-Msample memory that allows them to capture over 400 ms of data at the maximum sampling rate without any performance reduction. Other features include a 12-bit resolution that is adjustable up to 16 bits in enhanced-resolution mode, 1% accuracy, an 80-Msample/s real-time sampling rate, and input ranges from ±50 mV to ±100V full-scale. The oscilloscopes include PicoScope6 software for Windows PCs. The application can save waveform data in a range of text and binary formats including CSV, PNG, BMP, and MATLAB for export to other applications. An API and examples are on tap for LabVIEW, C, C++, Delphi, and Visual Basic. Prices for the two-channel PicoScope 4224 and four-channel PicoScope 4424 are $769.66 and $1,233.98, respectively.
