How to Measure Insertion Loss – BitWise Laboratories

 At BitWise Laboratories, we emphasize the importance of accurate signal testing in modern communication systems. Understanding how to measure insertion loss helps engineers ensure optimal performance of cables, connectors, and other transmission components. Insertion loss refers to the reduction of signal strength as it passes through a device or medium. To measure it, a calibrated signal source and spectrum or network analyzer are typically used. The procedure involves transmitting a known signal, recording the output level, and comparing it to the input. A lower insertion loss indicates better efficiency and quality of the component under test. By mastering how to measure insertion loss, organizations can prevent data loss, maintain system integrity, and extend the life of critical infrastructure.
