Ripple
Using Ripple Measurements
Background The ripple function allows power supply ripple to
be measured with ease. The function allows
automatic vertical scaling to maximize the vertical
resolution of the measurement by isolating the AC
component from the DC waveform.
WARNING
Ensure safe working practices are adhered to when
working with live voltages. Failure to do so could
lead to electric shock or loss of life.
