2.0.L FWHM:14.26

2.15.L ( 270pF )  FWHM : 119.04

(ooops found the 'scope channel was on 20Mhz BW filter ) 

DC measurements.

At FEE64 :- +7.822 , -6.36, +4.937

at Filter output ( AIDA Cable input )  :- +7.96, -6.46, 5.37

at filter input:- +7.97, -6.476, +5.488

Set supply with these voltages and add filter.

Measured earth point to mains earth pin as 0.095ohms.

Power-up with nnaida2. ADCs Calibrate fine....successful boot.

Voltages at FEE64:- +7.802, -6.324, +4.887. I will adjust the power supply voltages to match the FEE64 previous setup.

2.0.L FWHM :13.83

2.15.L FWHM:116.6

So not really a difference in performance at this simple level.

Attached are some oscilloscope traces of the six voltage rails after the filter on the filter board. +5v & 0v , -6v & 0v, +7v & 0v relative to the earth on the filter board. 

Attached are some oscilloscope traces of the six voltage rails before the filter on the filter board. +5v & 0v , -6v & 0v, +7v & 0v relative to the earth on the filter board.

There is a nice sine wave at 235KHz that needs to be finished off perhaps. Otherwise the filter seems to be doing well.

Next set of 'scope traces are across the three supplies. +7v, -6v, +5v.

Sine wave is present ( 220KHz )  at 80mv, 80mv, 105mv.

Next I'll try this supply on nnaida12 ( detector negative ) ...... next entry ....
