Understanding how to measure insertion loss is essential for evaluating the performance of RF, optical, and communication systems. Insertion loss refers to the reduction in signal power caused by inserting a device into a transmission path. To measure it accurately, start by recording a baseline signal level using calibrated test equipment such as a network analyzer or power meter. Next, insert the device under test and measure the new signal level. The difference between the original and measured values, expressed in decibels (dB), represents the insertion loss. Accurate measurements require proper calibration, quality connectors, and controlled test conditions. At BitWise Laboratories, precise testing methods and advanced instruments ensure reliable insertion loss measurements, helping engineers optimize system efficiency and maintain signal integrity across applications.
