11.5 Output Ripple Measurements  
11.5.1 Ripple Measurement Technique  
A modified oscilloscope test probe was used to take output ripple measurements, in order  
to reduce the pickup of spurious signals. Using the probe adapter pictured in Figure 22,  
the output ripple was measured with a 1 µF electrolytic, and a 0.1 µF ceramic capacitor  
connected as shown.
