Description
Summary:A g‐value processor has been constructed for use with an electron paramagnetic resonance spectrometer, to calculate and display g values and place g markers on the chart recorder. It is also used to control the magnetic field and signal averager, for amplitude measurements at field positions determined by two g values. The device is based on a 6504 8‐bit microprocessor and is operated from a 4×4 keypad. It includes a system for magnetic field measurement and control which counts the resonant frequency signal from a nuclear magnetic resonance gaussmeter and it is provided with the IEEE 488 interface in order to read a microwave frequency counter.
