In this blog, we will examine the noise performance of various probing solutions with a Rohde & Schwarz (R&S) MXO 5 oscilloscope. The goal is to understand how to achieve the best low-noise solution all the way from the device under test (DUT) to the scope.
When it comes to acquiring a signal, traditionally, we consider the oscilloscope’s bandwidth, dynamic range, and some other features necessary to make a low noise measurement of a signal.
However, it is easy to forget the importance of looking at the signal chain between the scope and DUT. A high bandwidth oscilloscope is worthless if your probing solution does not have the dynamic range or low enough noise performance necessary for today’s power integrity measurements.
