This test system helps create tabular or algorithmic functions to compensate for non-ideal behavior in vector modulators.

Vector modulators are used to impose baseband modulation on RF signals, but non- ideal behavior limits the overall performance. The non-ideal behavior of the vector modulator is compensated using data collected with the use of an automated test system driven by a LabVIEW® program that systematically applies thousands of control-signal values to the device under test and collects RF measurement data.
