Calibrating signal paths in RF/microwave test signals

Keywords:RF test? microwave signal? signal path? application note?

In any RF test system the ability to achieve instrument-port accuracy at the device under test (DUT) will enhance measurement accuracy and repeatability. Unfortunately, the non-ideal nature of the cables, components and switches in the paths between the instruments and the DUT can degrade measurement accuracy. Vector or scalar calibration is usually required to characterize and correct for this loss of accuracy.

This application note provides an overview of three approaches that can be used to calibrate RF signal paths and produce accurate, repeatable measurements. It's important to note that these calibrations are a complement toand not a substitute forthe calibration of individual instruments within a system.
