Application Note: Easy Testing Of TV Transmitters' Out-Of-Band Emissions

Source: Rohde & Schwarz GmbH & Co. KG

During commissioning, maintenance and service, the essential operating parameters of a TV transmitter must be checked. One particularly demanding task is to measure out-of-band emissions, i.e. signal components in the transmitter's adjacent channels. High-power and low-power transmitters have similar specifications for this measurement. However, since low-power transmitters are often located at difficult-to-access sites, portable measuring equipment is a major advantage.
