IX. LabVIEW NMR Interface

Overview of SpinCore LabVIEW GUI Interface

SpinCore has developed an easy-to-use LabVIEW Graphical User Interface (GUI) that combines 

the Single Pulse NMR, T1 Inversion Recovery, and CPMG interfaces into one interface. It allows 

the user to run basic NMR experiments by simply setting the experiment parameters as described 

elsewhere in this manual. Extra features in LabVIEW GUI include lightning fast resonance finder, 

built-in FFT and phasing, CYCLOPS phase cycling experiments, 90 degree pulse width finder, and 

continuous scan mode. The following two figures are screenchots of the LabVIEW NMR Inferface.  

For more information see the LabVIEW manual at:

http://www.spincore.com/support/PBLV/PBLV_RP_NMRinterface_Manual.pdf

NOTE: A National Instruments license is not required to run the LabVIEW interface.
