Attached are the results from the first round of testing of this QUAD. What we see:
1) Very poor coherence at low f which I had a hard time improving
2) Some cross coupling between T and R on the main chain
3) Some minor cross coupling between some P and L on the main chain
4) The 3rd L mode or 2nd P mode is split and the 2 are cross coupled on the reaction chain
Attached are the plots of this QUAD compared to the data from the other 3 3IFO QUAD units.
Note, damped TFs and spectra to follow.
