SKAO RFI Facility Qualification: Metrology: Application Note
The Square Kilometre Array (SKA) Observatory (SKAO) radio frequency interference (RFI) and electromagnetic compatibility (EMC) standard defines different applicable emissions thresholds, depending on where a product is installed. This includes typical EMC testing like the IEC-61000-x or MIL-STD-461, up to the very stringent SKA telescope threshold levels.
All equipment located at the telescope sites must comply to the SKA RFI/EMC Standard telescope thresholds. Construction of the SKA in both South Africa and Australia will require many EMC testing facilities to qualify hardware systems or sub-systems manufactured across the world. It is important that all test facilities produce the same acceptable and comparable results.
This presentation describes the minimum requirements to which a facility must comply to be considered an SKAO accredited RFI/EMC test facility, and a test facility can be certified to a certain threshold level capability. The presentation will furthermore touch on RFI qualification test procedures to verify compliance of hardware systems or sub-systems to the SKA RFI/EMC Standard requirements.

Biography:
Braam Otto received his B.Eng in Electrical and Electronic Engineering, as well as his B.Sc. in Information Technology and Computer Science at the Rand Afrikaans University in Johannesburg, South Africa in 2002. He received his M.Eng in Electrical and Electronic Engineering at the University of Johannesburg in 2004 where his thesis focussed on Adapting a Binary Neural Network for Error Correction Decoding. Braam continued to complete a Ph.D. in Electrical Engineering under supervision of Prof. Howard C. Reader at the University of Stellenbosch in the Western Cape of South Africa in 2009 with a dissertation entitled Direct Current Conductor Corona Modelling and Metrology.
Utilising his experience in metrology, computational electromagnetics and electromagnetic compatibility (EMC), he has been involved in the radio frequency interference (RFI) mitigation efforts of Square Kilometre Array project for 13 years. He is currently the Radio Frequency Interference (RFI) Manager at the Square Kilometre Array Observatory headquarters situated at Jodrell Bank in the United Kingdom, focussing on both SKA-LOW and SKA-MID in Australia and South Africa respectively.
