During the design phase, optimizing performance is greatly dependent upon the quality of your test. How do you go about ensuring that you've got the best probe for the job?
In an EDN article, Teledyne LeCroy's Stephen Mueller explains how to predict the performance of your probe for your specific test setup. He also offers some tips for getting the best performance out of your probe.
Mueller takes a look at the basic 10:1 probe, and gives examples of how estimating values for ground lead inductance and source impedance will allow you to plot the transfer function to get a good idea of the performance you can expect from your probe.
A common connection is the use of the long alligator lead. Mueller looks at the effect this ground lead has on the probe's bandwidth and frequency response. You can read the entire article here.
