Why Histograms and Free Run Matter

Oscilloscopes are key tools for power integrity measurements. With decreasing DC voltages and tolerances, techniques for accurate power rail testing have to be refined constantly. This article presents a new, widely unknown approach which reduces test times significantly. It combines waveform histograms and free run trigger mode, which lets developers capture and analyze a much higher percentage of rail activity than the traditional method.

Oscilloscope Probe Considerations

A basic knowledge of the probe types and their performance capabilities is important because their operation can affect the whole system under test and measurement results obtained.
