The aerospace industry requires data-acquisition systems with high-accuracy A/D conversion, a large channel capacity, and physically-distributed channels. Computer automated measurement and control (CAMAC) provides an ideal solution to meet these requirements. CAMAC-based systems are built to a nonproprietary specification and can provide thousands of channels distributed over an area greater than 10,000 feet with an aggregate throughput of up to three megabytes/second to the host computer. I/O modules include interfaces for ARINC-429 and MIL-STD-1553B as well as transient data recorders with a 1.3-gigahertz sampling rate. A CAMAC-based system called Tachion is also described. This system can acquire analog data and transfer this data to disk at rates up to 9.6 megabytes/second. The performance of a CAMAC-based system is further enhanced by computer interface hardware and software that support list processing. Also, the high level of standardization of the CAMAC command structure allows the use of a single software driver that is unaffected by the types of I/O modules in the system.
