B Parameters
70 NM21283A-A
The I-Phi parameters contain parameters that are related to I-Phi measure-
ments. The parameters are shown in Table B.2.
The noise measurement parameters describe how to make a white noise
measurement. The parameters are described in Table B.3.
The FFT parameters describe how the spectral calculations are performed.
The parameters are listed in Table B.4.
