How to Measure Insertion Loss with a TDR – Bitwise Laboratories
Understanding how to measure insertion
loss with a TDR is essential for evaluating signal integrity in
high-speed circuits. Bitwise Laboratories recommends using a high-resolution
Time Domain Reflectometer (TDR) to send a fast-rising edge pulse through the
transmission line. By analyzing the reflected and transmitted signals,
engineers can determine insertion loss by comparing input and output
amplitudes. Factors such as impedance mismatches, cable length, and material
properties impact accuracy. Proper calibration and de-embedding techniques help
minimize errors. Bitwise Laboratories provides advanced TDR solutions for
precise insertion loss measurements, ensuring optimal performance in PCB
traces, connectors, and high-frequency applications. Using a TDR simplifies
insertion loss analysis, making it an indispensable tool for reliable
communication and RF system design.
