Abstract: A power meter having a sample and hold circuit, a trigger signal generator, and a data processor is disclosed. The sample and hold circuit receives an input signal, V(t), and generates a measurement of that signal at a time determined by a trigger signal that is generated by the trigger signal generator. The trigger signal generator generates a plurality of trigger signals over a sampling time period thereby causing the sample and hold circuit to generate the measurements at a plurality of non-evenly spaced times during the sampling time period. The data processor processes the received measurements to provide a measurement of a desired signal property such as mean power or peak power to within a predetermined error.
