This International Standard gives guidance on the measuring methods for major microwave properties, such as return loss, forward loss, reverse loss, phase shift and group delay, of microwave ferrite components.
NOTE 1 - The methods of measurement are compiled after the model of IEC 60510-1-3.
NOTE 2 - Network analyzers are being used by most manufacturers to evaluate such properties of microwave ferrite components at present. However, knowledge of basic measuring methods is necessary for understanding the general purpose of measurements including the use of network analyzers. Therefore, orthodox methods of measurement are described herein.
