EVS-EN IEC 62037-1:2021

This part of IEC 62037 deals with the general requirements and measuring methods for intermodulation (IM) level measurement of passive RF and microwave components, which can be caused by the presence of two or more transmitting signals.
The test procedures given in this document give the general requirements and measurement methods required to characterize the level of unwanted IM signals using two transmitting signals.
The IEC 62037 series addresses the measurement of PIM, but does not cover the long-term reliability of a product with reference to its performance.
