Abstract
Systems and methods are provided for calibrating a receiver in an RF system having a device under test (DUT) configured to receive at least one input signal and output at least one response signal. A method comprises setting a drive level of the RF system and making a pair of measurements at the drive level. Each of the measurements is made in a different gain state at a receiver. The method also comprises calculating a calibration factor for the receiver which is a ratio of the pair of measurements. These systems and methods can be used to calibrate receivers while preserving vector information and removing dynamic match effects.
