Hi,I found something:
IM 2 =a 2 /a 1 *U, HD 2 =1/2*a 2 /a 1 *U
where a 2 , a 1 are coefficients.
U is signal amplitude.
and
IM 3 =3/4*a 3 /a 1 *U 2 , HD 3 =1/4*a 3 /a 1 *U 2
IM 2 =2HD 2 , IM 3 =3HD 3
Under low-distortion conditions, there is thus a one-to-one
correspondence between harmonic and intermodulation
distortion. It is thus sufficient to specify only one of them.
From Sansen, Distortion in Elementary Transistor Circuits
IEEE Transactions on Circuits and Systems Vol 46, No 3, March 1999Cool that we only need to worry about which ever is easiest to
measure and the other is related.
