A digital or analog oscilloscope can be used to measure the output ripple. The oscilloscope should be set for the following:
Test points TP6 and TP8 can be used to measure the output ripple voltage. Place the oscilloscope probe tip through TP6 and rest the ground barrel on TP8 as shown in Figure 7-1. Using a leaded ground connection can induce additional noise due to the large ground loop.
