My friend prepared a oscope.
there is 2 mv fluctuate in supply voltage with 100 hz frq but when we connect supply to board this fluctuate changed to 200mv with 10M freq How we can win against this problem also when all channel connect to gnd VA1 and VA2 are the same VB1 and VB2 are the same too,But there is 1-2 lsb difference between these two groups! |
