Digitaler Spektrumstabilisator für schnelle Analog-Digital-Konverter

Abstract A versatile spectrum stabilizer is described, suitable for all ADC's with a digital parallel output and a pilot pulse at the end of the conversion. The stabilizer is especially developed for a 100 MHz ADC, but it is independent of the digitizing rate and the mode of conversion. The unit has a maximum cyclus time of 2 μsec and permits a parallel transfer rate of 500 kHz. The stabilizer corrects the effects of gain drift and is insensitive to statistical errors.
