A low-cost microcomputer-based scanning instrument controller is described which has been used with both a Fabry-Perot interferometer and a grating monochromator. The system is based on a commercially available single-board computer. The controller can be used in either a passive mode, where it functions as a replacement for a multichannel analyzer, or in an active-control mode. Only the read-only memory held program need be changed to adapt the device to a scanning instrument in either mode. Interface circuitry and typical programs are described.
