Specials delivered in 7 days

 

Richard Marshall 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.

 

 

Further requests lead to the design and supply of the complete set of jigs specified by EN55103-2 Annexe B including the Equaliser/Injection transformer to Figure B4.

As RML catalogue items these jigs have subsequently been supplied to Equipment manufacturers and Test Houses in Japan and the USA as well as Europe.

 

Richard Marshall is currently involved in the development of other test jigs for future updates to Standards. Enquiries for specials are always welcome.
