The SMA connector, J6, is used to measure the output voltage ripple and transient response. Connect the SMA connector directly to the oscilloscope with a coaxial (coax) cable, instead of using a 10x oscilloscope probe, to achieve the best results. This enables the use of the smallest V/div setting on the oscilloscope to view the ripple. The EVM contains a 49.9Ω resistor in series with the SMA connector to block reflections on the coax cable. Either the high-impedance or 50Ω terminated setting on the oscilloscope can be used.
