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.
