Modern digital set-top boxes usually offer optimal picture and sound quality. However, if they have not been subjected to EMC (electro-magnetic compatibility) compliance testing, your TV set may emit crackling noises and picture interference can be pronounced. This may be trig-gered, for example, by sparks on the collector of an electric motor (impulsive noise). To remedy this problem, Rohde & Schwarz has developed a simple solution enabling set-top box manufacturers to test their products
for compliance with relevant EMC regulations.
