Abstract:
1. A method for precise measurement of the dependency on amplitude and phase of a plurality of high frequency signals obtained from accelerator electrodes, comprising the following steps: a) directing alternately by means of a radio frequency (RF) switch each of a plurality of analogue input signals to each of a plurality of RF processing units; b) amplifying the analogue input signals in the RF processing units in order to adjust the analogue input signals to the measuring range of a plurality of analog-digital (A/D) converters; c) directing the amplified analogue input signals to the plurality of A/D converters and converting the amplified analogue input signals to digital signals; d) directing the digital signals to a digital corrector; e) correcting the digital signals by means of correction signals from a circuit for synthesis of inverse model of systematic errors, wherein correcting signals from the circuit for synthesis of inverse model of systematic errors are obtained in a manner that the digitized signals are led directly after the digital corrector through the digital receiver to the low-pass filter where they are treated by means of a circuit which mutually compares the signals and, in order to identify the systematic errors of the signals exiting the A/D converter and entering the digital corrector, creates correcting signals which are directed back to the digital corrector; f) collecting digital signals exiting the digital corrector in a digital switch and directing an ordered recombined number of digital signals to a plurality of digital receivers; and g) filtering the recombined number of digital signals in a plurality of low-pass filters.
