The hardware referred to is the CASSPER correlation analyzer by Scientific Applications & Research Associates, Inc.
The hardware used the principle of correlation analysis, analyzing the phase correlation between multiple (minimum 2) test channels. The correlation determination between channels requires a significant data processing effort per data and time point. On the state-of-the-art hardware available at the time the data processing was really too slow for any real-time work, causing a horrible screen refresh rate in most cases, but it was great for source finding during bench debugging with some patience. Later hardware and software upgrades solved some of the processing speed issue, I’m told, but the evaluation unit I had was too slow for the type of work I was doing. It was discontinued in 2008 (www.sara.com/EM/cassper/index.html). Maintenance was available through [email protected] into 2009 according to that page.

One of the members of our community is looking for someone familiar with it. I have never heard of it. http://www.eeweb.com/discussions/caspr/ Thanks, Cody - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
