measurement Amplitude units will be available or not, and
how to convert between them. Select None (default
setting) if you just want standard Amplitude units, with a
simple dB offset supplied by the correction table. This
makes the correction basically identical to a Cable
correction. To get Field Strength units, you must choose
either dB /m (E-field or dipole antenna), or dB S/m
(H-field or loop antenna) to properly identify the Antenna
Factors in the table. The scalar measurement Amplitude
units (either standard or Field Strength) will then be
available at Ampl/more Unit. Learn how in

— When one Freq/Value pair is entered, that correction value is
applied to the entire displayed frequency span.
— When two or more Freq/Value pairs are entered, the data points
between the lowest and highest frequencies are corrected. Linear
interpolation is applied between frequencies when necessary.
