    Notes: The scan drive of a stepper motor, signal detection and data processing of the recorded Raman signals were controlled by a compatible IBM-PC/XT which was connected to a Jarrell–Ash 25-400 spectrometer. Excitation source fluctuations were eliminated by the simultaneous detection of a small portion of laser light. This reference and the Raman signals were transmitted to the 8-bit parallel port of the IBM by multiplexing. The parallel port was modified to bidirectional data transfer so that control and signal processing required only one port.

    Notes: 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.
