Abstract
A system has an extended dynamic range for measuring distortion in an output signal of a device under test (DUT), the output signal having at least a first fundamental signal. The system includes a first combiner and a test receiver. The first combiner is configured to inject a first cancellation signal generated by a first signal source into the output signal from the DUT, at least one of a first magnitude and a first phase of the first cancellation signal being adjustable for suppressing the first fundamental signal. The test receiver is configured to receive and measure the output signal having the suppressed first fundamental signal.
