The interface controller of an IBM personal computer, which is supported by the CAMAC–COMPEX protocol, is described. This controller is used in the central crate of the data acquisition and readout system of the magnetic spectrometer of the SVD setup. The system has 28 addressable crates; the controller's response speed in the central crate is 2.3 s/word. 相似文献

A schematic diagram of a device for the synchronous inputting of video and external analog signals into a computer is described, in which the video signal for certain TV lines is replaced by an analog signal corresponding to the state of the controlled device. This circuit was used in experiments to study amplitude–phase characteristics of the coherent radiation scattered by biological objects. 相似文献
