2.0.L FWHM:14.26
2.15.L ( 270pF ) &nbsp;FWHM : 119.04
(ooops found the 'scope channel was on 20Mhz BW filter )&nbsp;
DC measurements.
At FEE64 :-&nbsp;+7.822 , -6.36, +4.937
at Filter output ( AIDA Cable input ) &nbsp;:- +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 &amp; 0v , -6v &amp; 0v, +7v &amp; 0v relative to the earth on the filter board.&nbsp;
Attached are some oscilloscope traces of the six voltage rails before the filter on the filter board. +5v &amp; 0v , -6v &amp; 0v, +7v &amp; 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 ) &nbsp;at 80mv, 80mv, 105mv.
Next I'll try this supply on nnaida12 ( detector negative ) ...... next entry ....&nbsp;
