We describe a straightforward method of separately characterizing up-conversion and down-conversion in microwave mixers with a sampling oscilloscope. The method mismatch-corrects the results, determines both magnitude and phase, and uses a novel time-base correction scheme to improve the accuracy of the measurements.
