How to Measure Insertion Loss – BitWise Laboratories
Understanding how to measure insertion
loss is essential for anyone working with high-frequency signals,
communication systems, or network testing. At BitWise Laboratories, we simplify
this complex concept so engineers and technicians can achieve accurate,
repeatable, and reliable results. Insertion loss refers to the amount of signal
power lost when a device, connector, or component is inserted into a
transmission line. Measuring it correctly helps diagnose performance issues,
optimize system design, and ensure compliance with industry standards.
To begin, proper calibration is the foundation. Using
high-quality test equipment and ensuring the environment is noise-free is
extremely important. Next, connect the device under test (DUT) to a vector
network analyzer (VNA) or similar tool designed for precise signal assessment.
BitWise Laboratories provides specialized instruments that help you determine
how to measure insertion loss with superior accuracy and minimal error. Our
tools allow you to record S-parameter data, especially S21, which directly indicates
how much signal passes through the system.
Once the DUT is connected, run the sweep across the required
frequency range. The analyzer will display the measured loss in decibels (dB).
A higher insertion loss value means the device is allowing less signal to pass,
which may indicate issues like impedance mismatch, poor build quality, or
internal damage. Reviewing the data across different frequencies helps identify
whether the loss is consistent or occurs in specific bands, which is essential
for troubleshooting.
BitWise
Laboratories ensures that every user has access to advanced testing
technology that is easy to operate yet highly accurate. Our commitment to
precision and innovation makes us a trusted name among engineers working to
optimize signal integrity. With the right tools and a clear understanding of
the process, measuring insertion loss becomes simple, reliable, and efficient.
