The CompuScope 1220 provides two input channels, 12 bit vertical resolution, 20 MS/s simultaneous sampling rate, 10 MHz bandwidth on most input ranges, external triggering and external clocking. Input ranges as low as ± 50 mV as well as AC/DC coupling and 50 Ohms / 1 MOhms impedances are all software-controlled for maximum versatility. DC Accuracy is typically ± 0.5% of full-scale input. The card can also be equipped with up to 2 GigaSamples of on-board memory. Up to eight cards can be combined as a Master/Slave system to provide up to 16 simultaneous input channels. Software Development Kits (SDKs) for C/C++, MATLAB, and LabVIEW are available, with support for Windows 95/98, NT, XP and Windows 2000.
