A CONTROL UNIT FOR A PULSED NQR-FFT SPECTROMETER


Abstract

This paper describes the development of functional and algorithmic methods to automate pulsed NQR-FFT radiospectrometer. Module controlling this device is based on a programmable logic device (PLD). The objective of this work is to develop a control unit for operational control and setting all required parameters portable NQR radiospectrometer. Radiospectrometer control module is designed as a block structure, which includes the main board, LCD, controls and ports IO. The sample unit tested in complex with frequency synthesizer and NQR radiospectrometer pulse sequences shaper. The test results showed the device matching its functionality to all regulations that apply to this class of relaxation and pulsed resonance spectroscopy equipment.
