Objective data sheet
Intermodulation measured relative to either tone with analog input frequencies f
and the total amplitude of both signals provides full-scale to the converter ( 6 dB below full-scale for each input signal).
d3
the ratio of the RMS value of either input tone to the RMS value of the worst case second order intermodulation product.
(IM3)
is the ratio of the RMS value of either input tone to the RMS value of the worst case third order intermodulation product; d2
