RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

TekBox EMC Pre-Certification Testing

TekBox Digital Solutions has a presentation in PDF format which discusses product EMC certification testing and the reality that greater than 50% of items fail the first go-round. Since the formal, on-the-record testing is usually an expensive proposition, it behooves companies to perform pre-compliance testing that will provide a high level of confidence that the product will have success on the first pass. Most consumer type devices can be tested in a tabletop-size TEM cell (transverse electromagnetic wave) with proper instrumentation that includes calibrated antennas / RF probes and measurement test equipment.

You probably will not be surprised to learn that TekBox manufacturers a lot of the equipment needed to carry out EMC testing. Saelig Company, an RF Cafe advertiser, happens to represent the TekBox line.

About 15 years ago I was involved in a lot of RF emissions testing that involved using TEM cells, and can remember paying a couple thousand dollars for fairly small models. Things have really changed since then. You can now buy a 4.25" x 7.75" x 15.25 " TEM cell for less than $600 - amazing. Saelig also sells spectrum analyzers and other necessary ancillary equipment at good prices.
