hi,
which one is preferred method on measuring output ripple fo switchers, output capacitor probed with a 50ohm coaxial terminated at the scope of 50ohm or using with 10:1 oscilloscope probe with 1M input termination(tip and barrel method)?
I saw one article that measuring outout ripple should be 50 ohm enviroment...Please give the best reason thanks
