In old good analog world, I would high-pass or band reject filter these
fundamental frequencies. Then it could be possible to recover the wanted
mixed harmonic using autocorrelation or band-pass filtering.  I suppose,
that tit is necessary to measure a band around the measured harmonic in
order to estimate the increase of general noise level in your circuit
caused by the test signals f1 and f2.
