Signal Integrator and Computer

Computer control of the room temperature shim currents that control the field homogeneity, of sample spinning rates, autosamplers, pulse sequences, and many other aspects of the instrument operation is a necessity. 

All NMR spectrometers are equipped with a signal integrator to measure the area of peaks. The area often appears on the NMR spectmm as a step function superimposed on the spectrum, as seen in Fig. 3.18(a), but is also printed out in a data report as well.
