Measurement Functions
For a description of the measurement functions of wide bandwidth harmonic
measurement mode and how they are determined, see section 7.11. Measurement is not
allowed for measurement functions related to the functions above that have limitations.
For a list of measurement functions that cannot be measured, see appendices 10 and 11
in the
User’s Manual IM WT3001E-01EN .
