About this Manual
e only significant difference between the NFA 1000 and the NFA
400 in this manual is the fact that the NFA 1000 allows a three-di-
mensional potentialfree measurement of the E-field, while the NFA
400 can only be used for one-dimensional potentialfree measure-
ments of the E-field. This distinction is specified in detail in the rel-
evant chapters
