An automatic test system based on virtual instrument ESR

Electron spin resonance instrument is important equipment in the modern physics laboratory of higher learning facilities. The new design of intelligent ESR (electronic spin resonance) is composed of three parts, which are the magnetic field components, resonance instrument host and PC-application software, using the power of virtual instrument software LabVIEW designed for PC-application software, through RS-232C serial port recording and keeping the data transmitted from the host, generating resonance line, and calculating the g factor, line width and magnetic field component and other parameters to meet the test requirements, improve the measurement accuracy. The design of the virtual instrument panel and interface are also more beautiful and practical.
