Method for the Precise Measurement of Dependency on Amplitude and Phase of Plurality of High Frequency Signals and Device for Carrying Out Said Method |
摘要 |
The present invention refers to a method for the precise measurement of dependency on amplitude and phase of a plurality of high frequency signals, preferably in the synchrotron accelerator of elementary particles. The essence of the solution according to the invention lies in that with a single measuring device and without any aliasing it is achieved a resolution of 0.2 micron and repeatability of measurements of 1 micron down to the lower frequency limit of a few MHz. A method according to the invention includes alternately directing, with a radio frequency (RF) switch, each analogue input signal to each of a plurality of RF processing units; amplifying each analogue input signal in each RF processing unit in order to adjust signals to the measuring range of a plurality of analog-digital (A/D) converters; directing each amplified analogue input signal to each of a plurality of A/D converters; converting the analogue signals to digital signals; directing the digital signals to a digital corrector; correcting the digital signals by means of correcting signals from the inverse models of evaluated systematic errors; collecting corrected digital signals in a digital switch and directing the ordered recombined number of digital signals to each of a plurality of digital receivers; and filtering the recombined number of digital signals in a plurality of low-pass filters.
