Abstract :
With a new, broadband matched test set-up, cable and connector screening effectiveness measurements over more than 7 frequency decades can be performed. The set-up allows to measure directive effects, which occur on both cables and connectors due to several discrete leakage points. High dynamic range (up to 150 dB) is achieved by using a combination of synthesized signal generator, synthesized spectrum analyzer and low noise preamplifier. This set-up will be introduced as the standard test method for connector screening effectiveness measurements by IEC and is also suitable for cable measurements.
