IEEE 213-1961

IEEE 213-1961 is a technical standard for measuring conducted radio interference output to the power line from FM and television broadcast receivers over the 300 kHz to 25 MHz range. It provides a defined testing framework for assessing how receiver equipment can affect power-line environments, which is important for interference control and comparison of results. As a superseded standard, IEEE 213-1961 remains useful for understanding historical compliance methods and legacy broadcast receiver testing practices.

About IEEE 213-1961

This standard addresses methods of measurement for conducted interference emitted by FM and television broadcast receivers into the mains supply. IEEE 213-1961 is focused on the test approach rather than product design, helping establish consistent procedures for evaluating interference in the 300 kHz to 25 MHz band. In practice, it supports technical review of receiver behavior on the power line and gives engineers a repeatable basis for comparing measurements across similar equipment and test setups.

Where is IEEE 213-1961 used?

IEEE 213-1961 is most relevant in broadcast receiver testing, laboratory measurement, and engineering review of power-line conducted interference. It applies to FM and television receiving equipment where emissions into the supply network may need to be characterized during development or verification. The standard is also useful in compliance-oriented workflows, especially when evaluating legacy devices, comparing test results, or documenting interference performance in communication and signal-processing related environments.

Importance in practice

Using IEEE 213-1961 helps create more consistent interference measurements, which reduces uncertainty in testing and supports clearer engineering decisions. For broadcast receiver manufacturers and test labs, a defined method is valuable when checking whether equipment introduces unwanted conducted noise onto the power line. IEEE 213-1961 can also aid procurement and archival review by providing a recognized reference for older designs, making it easier to interpret legacy documentation and maintain measurement consistency.
