Better Satellite Link Distortion Testing Using Spectral Correlation Method - Application Note
Like ground-based systems, the capacity and complexity of space-based communications is growing exponentially. System designs are being pushed to their limits as the need for greater capacity leads to faster data rates and higher bandwidths. As always, signal power is a key metric, and the need for more power across wider channels means that power amplifiers spend more time inside their nonlinear operating region. The result of this is signal distortion, and systems designers need to find ways to either reduce this distortion or work around it. Making accurate, insightful measurements of this distortion is the first step in solving the problem.

Probing a Midpoint of a Transmission Line that is Not Load Terminated - White Paper
With the advent of variable on die termination (i.e. ODT) many systems like low power double data rate memory (LPDDR) have the ability to either terminate a line in its characteristic impedance for high speed operation or terminate it with an open for lower speed operation. Many times there is a desire to probe the transmission line to monitor the signals on the line. When the transmission line is terminated in close to its characteristic impedance, the signals can be readily observed. However, if the line is terminated in an impedance that is not close to the characteristic impedance then it may not be possible to accurately measure the signals.
