Specials delivered in 7 days

Richard Marshall Limited has recently shipped a set of custom-made test jigs to a well-known EMC test house just seven days after receiving the order.

The jigs were for testing the common-mode immunity of balanced signal ports of professional audio equipment according to EN55103-2. They comprised a Test Interface as defined by figure B1 of the Standard together with the necessary close-tolerance calibration jig.

The principal obstacle to speedy delivery of these items was the procurement of components. A 480pF variable capacitor is not a common item these days!

Richard Marshall is currently involved in the development of other test jigs for future updates to Standards.
