Input/Output Ripple and Noise Measurements:
The input reflected ripple is measured with a current probe and oscilloscope. The ripple current is the current through a
12H differential mode inductor, Lin, with esr  10 m, feeding a capacitor, C1, esr  700 m @ 100kHz, across the
module input voltage pins. The capacitor C1 across the input shall be at least one 220F/100V electrolytic capacitor along
with two 1uF to 2.2uF/100V ceramic capacitors. Two 220F/100V electrolytic capacitors and two 2.2uF/100V ceramic
capacitors are recommended. A 220F/100V capacitor for C0 is also recommended.
The output ripple measurement is made approximately 7 cm (2.75 in.) from the power module using an oscilloscope and
BNC socket. The capacitor Cext is located about 5 cm (2 in.) from the power module; its value varies from code to code
and is found on the electrical data page for the power module of interest under the ripple & noise voltage specification in
the Notes & Conditions column.
