figure 1. FID GUI screen shot

To the right is a screen shot of the "FID GUI" which allows the digitized FID to be displaced as well as the spectrum of that FID. It also has a shimming tool to adjust the shim offset currents to try to improve the spectral linewidth. There is also a flip angle calibrator which steps thru RF pulse amplitudes from 0 to full power and plots the signal amplitude as a function of power.
