Title: Design and measurements of lock-in amplifier based on LabVIEW
Abstract: A virtual lock-in amplifier was designed based on NI LabVIEW software platform and PCI-6251 acquisition card.A series of measurements like phase sensitive detection,noise suppression by even and odd harmonics and frequency response had been done with a good accuracy.The measurement results demonstrated that this virtual lock-in amplifier had a good and even better performance of noise suppression compared with normal instrumental lock-in amplifier.
