The Process item is only displayed when a Signal Window is active. Different commands for
data processing are summarized in this pull-down menu:
Figure 6.14: The Process Pull-Down Menu
Within the context not all commands may be reasonable, in which case they will be grayed.
The following series of built-in signal processing features are available:
The Fit Command
This command is only available in connection with calibrations. You can fit your calibration
data and display the fit results (see
Info Views , point 4).
The FFT, Magnitude, Power and Absolute Commands
A Fast Fourier Transform of measurement data will be performed using the FFT command. If
the NMR signal is observed in complex mode (real and imaginary part of the signal) the
Magnitude ([Re2+Im2]1/2) or the power spectrum can be calculated. From the real,
imaginary or complex data, the Absolute values can be calculated.
The Signal Flip, and the Signal Swap Command
The signal can be mirrored with respect to an offset frequency of 0 using the Signal Flip
command. The Signal Swap command exchanges the real and imaginary part.
