We now use discretes and have a placement machine. - the noise measurements above should be regarded as non-optimal. - channels #1, 3, 61, 63 were notworking due to faulty test capacitors The shaping time used is also non-optimal. For example, for FEE64 2b:27:4b changing the shaping time from 0x01 to 0x08 changed the peak width from 12.5 to 8.9 ch FWHM.
