Shielding and Filtering Are Not Independent of One Another

By Keith Armstrong

I have lost count of the number of times I have been asked to fix an EMC problem, only to find that a shielding box has been designed or purchased to provide XdB up to fMAX. Or a filter has been designed or purchased with a similar specification, but to reduce cost the filter has been mounted on a printed circuit board (PCB) inside the box, with a cable from it entering or exiting the box through a plain connector.

Precise Measurements on High-speed Digital Signal Lines with the R&S®ZNB

By Rohde & Schwarz
When performing tasks such as verifying digital high-speed signal structures on PCBs, measurements have to be carried out on certain layers without the effects of probes, probe pads, VIAs, lead-ins and lead-outs. This requires the use of accurate de-embedding algorithms to calculate and remove these effects from the measurements, leaving only the result for the area of interest. Download the app note.
