As per my knowledge for ripple measurement, we need to use a tip and barrel probe because it has less loop area and the oscilloscope bandwidth
should be set to 20Mhz to avoid unwanted external noise pick-up. Please correct me if I am wrong.
I am going through the below article about ripple voltage measurement.
In paragraph 2nd of the Proper Measurement Techniques Using an Oscilloscope Probe,it says that " The loop created by the probe's
return path causes an inductance which can amplify internal noise and pick up external noise"
I have 2 questions regarding this,
1)May I know how the loop inductance amplifies the internal noise?
2)For external noise pick up the loop acts as an antenna and picks up the noise. Please correct me If I am wrong.

How to Measure Ripple and Transient in Power Supplies | CUI Inc
Two of the most common specifications when evaluating a power supply are ripple and transient. While they may seem like simple measurements, there are two important aspects that should be kept in mind to obtain the correct data. The first is the measurement technique when utilizing...
