Simple enhancements to the nose-to-nose method of characterizing samplers are described. The technique is applied to a millimetre-wave sampler. These allow sampler magnitude and phase response to be measured to 150GHz and above. Excellent agreement is found with magnitude measurements made using conventional traceable power sensors.
