MAGNETIZING SIGNAL GENERATOR FOR COMPENSATION FERROMETERS

Ivan Zemánek – Petr Zemánek – Aleš Havránek

   A precise microprocessor controlled programmable generator of periodic magnetizing signals for compensation ferrometers was designed and realized. Generator digitally synthesizes and generates AC random waveform signals with amplitudes 0 - 10 V and frequencies 10 Hz - 120 kHz at sampling rates up to 20 MSPS and maximum 2048 samples per period. Generator exactly and reliably fulfils the most important functions of the compensation method magnetizing process - autonomous uninterrupted signal generation and simultaneous adaptive signal waveform correction. Results of measurement on realized generator are presented.
