Octopus Express CompuScope 8 CH, 25 MS/s, 16-bit, 20 MHz BWD, PCIe Digitizer


CSE8482 Octopus Express CompuScope is a 8 CH, 25 MS/s, 16-Bit with 20 MHz analog bandwidth, PCI Express digitizer board.

The Gage Octopus CompuScope family provides up to 8 channels in a single slot PCI Express (PCIe) or PCI card with up to 125 MS/s sampling per channel, and up to 16 GS of on-board acquisition memory. The Octopus CompuScope is available in 16-bit (CS84XX), 14-bit (CS83XX) A/D resolution models.

Lower-priced Octopus 14-bit (CS83XX) models provide the exact same functionality as the 16-bit (CS84XX), with the sole exceptions of lower vertical resolution and corresponding lower Dynamic Performance parameters (SNR, THD, SINAD, ENOB, SFDR) but with higher sampling rates.

GaGe CompuScope boards come with GaGeScope PC Oscilloscope Software. Further more there are Software Development Kit (SDK) C/C#, LabVIEW and MATLAB, supported on Wnidows as well as Linux Operation System.
