Time Domain Gating as a Measurement Tool, Not a Feature
Time domain gating is thought of as a feature that can be turned on or off, but this undersells its ability to reshape S-Parameter measurements by selectively including or excluding portions of the measured response.
Time domain gating is used to isolate or suppress an irrelevant region of a measurement and is a useful tool that extends what can be achieved with a VNA. Copper Mountain Technologies' Senior Scientist, RF Applications details how engineers can use this tool to:
Remove fixtures and adapters without full S-parameter characterization.
Eliminate multipath in free space measurements.
Improve the accuracy of material characterization measurements.
Diagnose transmission lines.
Improve measurement clarity.
It is a practical and effective way to eliminate fixture reflections, isolate a device on a circuit board, suppress multipath in a free space measurement, or improve the accuracy of material characterization.
