Patent ID: 6972552

Claim:
A method for precise measurement of the dependency on amplitude and phase of a plurality of high frequency signals obtained from accelerating electrodes, comprising the following steps: 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; amplifying said analogue input signals in said RF processing units in order to adjust said analogue signals to the measuring range of a plurality of analogue digital (A/D) converters; directing said amplified analogue input signals to said plurality of analogue digital converters and converting said amplified analogue signals to digital signals; directing said digital signals to a plurality of amplification correctors; correcting said digital signals by means of correcting signals from an amplification equalizer; collecting digital signals exiting said correctors in a digital switch and directing an ordered recombined number of digital signals to a plurality of digital receivers; and filtering said recombined number of digital signals in a plurality of low-pass filters.
