FAQ 2010-05-14

My InfiniiMax probe fails calibration or does not accurately pick up the cal signal when I use the E2655A test fixture. What could be wrong?
The first step in troubleshooting a failed probe calibration should be to compare the actual signal and the probed signal. If the probed signal does not track the actual signal well, it is most likely due to a poor connection.

FAQ 2009-06-18

What happens if I probe somewhere in the middle of differential traces? (N1021B differential TDR probe)
The net effects of probing in the middle of traces are (1) you will greatly attenuate the transmitted signal, (2) you will cause a big discontinuity in the line that will send a reflection back to the source, and (3) the signal viewed using the TD...

FAQ 2009-06-18

Why should I calibrate the N1021B differential TDR probe at its connector side as opposed to its tips?
Calibration requires a short to ground for each single-ended portion of a differential signal. Because the differential probe does not have ground at the tips, it is not possible to calibrate to the tips of the probe ...
