Test Method

Output Ripple & Noise Test:

The output ripple is composed of fundamental frequency ripple and high frequency switching noise spikes. The fundamental switching frequency ripple (or basic ripple) is in the 100KHz to 1MHz range; the high frequency switching noise spike (or switching noise) is in the 10 MHz to 50MHz range. The switching noise is normally specified with 20 MHz bandwidth to include all significant harmonics for the noise spikes.

The easiest way to measure the output ripple and noise is to use an oscilloscope probe tip and ground ring pressed directly against the power converter output pins, as shown below. This makes the shortest possible connection across the output terminals. The oscilloscope probe ground clip should never be used in the ripple and noise measurement. The ground clip will not only act as an antenna and pickup the radiated high frequency energy, but it will introduce the common-mode noise to the measurement as well.

The standard test setup for ripple & noise measurements is shown in Figure F. A probe socket (Tektronix, P.N. 131.0258-00) is used for the measurements to eliminate noise pickup associated with long ground clip of scope probes.
