Zusammenfassung:To enable signal averaging on our VG ESCALAB MK-1 spectrometer we designed a digital ramp generator with repetitive mode of operation for each selected energy analyser sweep time. For digital data acquisition purposes we constructed a dedicated microcontrolled acquisition unit performing digitization of the ESCA spectrum in 4096 channels of 12-bit words. Data flow is controlled by a 6809 microprocessor driving a parallel interface adapter. Two RS232C serial links are provided for communication with a terminal and a mass storage unit.
