The purpose of this test procedure is to determine the reflection at any port, or the transmission between any two ports of a properly terminated device, as measured across a frequency range of interest. Depending on use of the data, return loss, insertion gain or loss, isolation, response variation or bandwidth can be derived.

This specification is designed for devices with a characteristic impedance of 75 ohms. However, these principles can easily be extended to devices of other characteristic impedances. See more
