<p>2.0.L FWHM:14.26</p> <p>2.15.L ( 270pF ) FWHM : 119.04</p> <p>(ooops found the 'scope channel was on 20Mhz BW filter ) </p> <p>DC measurements.</p> <p>At FEE64 :- +7.822 , -6.36, +4.937</p> <p>at Filter output ( AIDA Cable input ) :- +7.96, -6.46, 5.37</p> <p>at filter input:- +7.97, -6.476, +5.488</p> <p>Set supply with these voltages and add filter.</p> <p>Measured earth point to mains earth pin as 0.095ohms.</p> <p>Power-up with nnaida2. ADCs Calibrate fine....successful boot.</p> <p>Voltages at FEE64:- +7.802, -6.324, +4.887. I will adjust the power supply voltages to match the FEE64 previous setup.</p> <p>2.0.L FWHM :13.83</p> <p>2.15.L FWHM:116.6</p> <p>So not really a difference in performance at this simple level.</p> <p>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. </p> <p>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.</p> <p>There is a nice sine wave at 235KHz that needs to be finished off perhaps. Otherwise the filter seems to be doing well.</p> <p>Next set of 'scope traces are across the three supplies. +7v, -6v, +5v.</p> <p>Sine wave is present ( 220KHz ) at 80mv, 80mv, 105mv.</p> <p>Next I'll try this supply on nnaida12 ( detector negative ) ...... next entry .... </p> <p> </p> <div> </div>
