Hi Everyone,
I have been writing again and this month's Technical Tidbit on my site
discusses verification of current measurements to detect errors caused
by electric field coupling to current probes. This is a possible
problem when measuring circuits having impedances above 50 Ohms or
that involve high voltages, such as ESD.
Abstract: Significant sources of error can exist in voltage and
current probes that are often not explicitly spelled out in
specifications. Verification of measurements is absolutely necessary
before decisions are made based on measurement results. Two methods of
verifying current measurements are described and experimental results
presented that build on a previous Technical Tidbit article.
The link to the article is the picture of the experimental test setup
at the bottom of the home page at http://emcesd.com .
