10 Factors in selecting an EMC Antenna

Webinar - "The 10 Factors You Need to Consider When Selecting an EMC Antenna"


The antenna is one of the least understood components in an EMC test instrumentation set-up, and a poor choice of antenna(s) can lead to multiple problems including erroneous test data, failed tests, lengthy or difficult test procedures, and challenges with repeatability. Useful to beginners and the more experienced alike, this webinar, presented by AH Systems, guides you through the key parameters that need to be considered when selecting an EMC test antenna. Attendees will also receive a handy check list for practical future reference.
