依靠灵活的信号发生器激励信号检测IQ调制器 Application Note Characterization of IQ Modulators Counts On Flexible Signal Generator Stimulus IQ modulators play a critical role in modern This application note describes several of the telecommunication. As demands for transmission important measurements design engineers routinely bandwidth and signal quality continue to grow, make on an IQ modulator. It illustrates how modern suppliers of IQ modulators are working on new arbitrary/function generators provide a stimulus to designs to address these requirements. During the characterize high performance IQ modulators design phase, the performance of new devices must thoroughly, with more flexi……
