ANUDAQ-20 is a low-cost IBM-PC based Data Acquisition card which can digitize analog signals at a maximum real time sampling rate of 20 mega samples per second with a bandwidth of 4 MHz. This is a full length card having a 16-bit EISA bus interface. It is having two independent channels which allows simultaneous operation. In addition it has external digital trigger input. This card can work with IBM-PC/AT and upward computer with operating system MS-DOS version 4.0 and MS-WINDOWS 3.1. This card has onboard 64kB static RAM per channel to increase throughput.
