Ripple
Power ripple is an important specification to consider for evaluating DC power supply.
It indicates the ripple quantity of the output DC voltage. The ripple analysis can
measure the current value, average value, minimum value, maximum value, standard
deviation, and count value of the ripples on the power output terminal.
NOTE
A 1X probe (e.g. PVP2150 and PVP2350) is recommended for the ripple measurements.
