vector signal generator (VSG)

Vector signal generators (VSG) are powerful signal sources often equipped with freely selectable function generators for the generation of digital signals, which are used to generate different modulation methods ofdigital and analog modulated signals such as amplitudemodulation (AM), frequency mod ulation(FM), frequency shift ke ying(FSK) or quadrature amplitude modulation(QAM). They are used to generate accurate test signals for testing advanced RF communications equipment. In addition to generating signals internally, many vector signal generators allow external RF signals to be downloaded to the generator for recording and playback. For example, external
