Interface for the control of an optical multichannel analyzer by an IBM PC−Example: Vidicon detectors of the series PAR 1250

This article presents an interface device connecting an IBM PC with an optical multichannel analyzer. The processor (optional 8088 or 80286/80386) is directly integrated in the synchronization logic of the data acquisition. This is carried out by transferring strobe pulses from the controller of the multichannel analyzer to the input ‘‘TEST’’ of the processor 8088. The specific conditions of the operation modes (e.g., signal accumulation modes and target scannings stabilizing the detector target) have been taken into account by the signal processing routine.
