Your neighbour's stereo system malfunctions when you are transmitting. What provision in Electromagnetic Compatibility Advisory Bulletin EMCAB-2 deems the stereo system's lack of immunity is the cause?

Correct Answer
A.
The field strength of your emissions, on your neighbour's premises, is below Innovation, Science and Economic Development Canada's specified immunity criteria
B.
The field strength of your emissions, on your neighbour's premises, is above Innovation, Science and Economic Development Canada's specified immunity criteria
C.
You are transmitting at or below your maximum permitted power
D.
The malfunction stops when you stop transmitting

B-001-025-001

"If the level of the transmitted signal exceeds the applicable field strength value on the premises of the affected equipment, it will be deemed that the transmission is the cause of the problem. If the field strength is less than the applicable value, the affected equipment's lack of immunity will be judged the cause. These criteria are not applicable to incidents involving the transmissions of AM, FM or TV broadcasting transmitters". (EMCAB-2)

When determining the field strength criterion per Electromagnetic Compatibility Advisory Bulletin EMCAB-2, what type of equipment describes devices often used in home entertainment systems, but not strictly speaking radio apparatus?

A.
Low-immunity equipment
Correct Answer
B.
Associated equipment
C.
Radio-sensitive equipment
D.
Broadcast receivers
