Description It is often desirable to measure the spectrum of the modulated baseband pulse of a quadrature amplitude modulated data set The usual method, which is not very satisfactory, is to send a pseudo-random data sequence into the data set and measure the transmitted signal with a spectrum analyzer. Here we present a new technique, based on the properties of so-called “perfect sequences,” which facilitates stable and accurate spectrum measurements.
