Challenges in interlab comparison of radiated emission measurement above 1GHz

Currently most of the Standard requires Radiated Emission Testing beyond 1GHz due to the advancement of Technology with the increase in oscillator frequency of the microprocessors, crystal frequencies and the move towards the use of wireless communication networks like Wifi, Zigbee, 3G / 4G Communication, Bluetooth, etc. This presentation focuses on common problems during inter laboratory comparison in EMC Laboratories which becomes more challenging with the increase in test Frequency mainly above 1GHz. Attempt is made in this presentation to identify the most common problems and identify the fix for those problems.
