A simple method to verify the bandwidth of your probe

In oscilloscopes or oscilloscope probes, bandwidth is a measure of the width of a range of frequencies measured in Hertz. Utilizing the built-in mathematical capabilities available in modern digitizing oscilloscopes, it is possible to derive the frequency response or the bandwidth characteristics of a probe based on the measured step response of a fast step signal. Among those several test methods, the time domain approach is the easiest to duplicate without needing expensive test instruments.
