10.8 Ripple Measurements

10.8.1 DC Ripple Measurement Technique

Details of output ripple probe are provided below. Decoupling capacitors are included to

minimize the effects of high frequency probe coupling and ensure a consistent

measurement set-up.

adapter, modified with wires for Probe Ground for ripple measurement. Two parallel

decoupling capacitors have been added (1.0

µF/50 V aluminium electrolytic and a

0.1

µF/50 V ceramic)
