Your neighbour's television receiver malfunctions when you are transmitting. What provision in Electromagnetic Compatibility Advisory Bulletin EMCAB-2 deems your transmission is the cause?
- AThe field strength of your emissions, on your neighbour's premises, is above Innovation, Science and Economic Development Canada's specified immunity criteria
- BYou are transmitting at or below your maximum permitted power
- CThe malfunction continues when you stop transmitting
- DThe field strength of your emissions, on your neighbour's premises, is below Innovation, Science and Economic Development Canada's specified immunity criteria
Correct answer: A — The field strength of your emissions, on your neighbour's premises, is above Innovation, Science and Economic Development Canada's specified immunity criteria. From the official ISED question bank, verified word for word.
Why
Your transmission is considered the cause of the interference because the radio energy reaching your neighbour's home is stronger than the level that their equipment is legally required to withstand. The full explanation — and one for every question — is in Pro.
