Signal Source - Understanding How to Improve Source Match
A review of common sources of mismatch errors and a measurement example of a method to improve measurement accuracy.
About this course
Source match is important because many test devices present non-50Ω matches. This mismatch between the source and the load impedance can be the cause of significant amplitude uncertainty. An explanation of what causes the mismatch and a detailed measurement example of how to dramatically improve it with an external attenuator is shown. Using attenuation wisely in your measurement setups can greatly reduce overall measurement error.
