Overview
Transcom Vector Signal Generator T3260A is a high performance signal generator with frequency range 250KHz to 6GHz and 160MHz wide RF modulation baseband. It generate various radio system signal format for testing both analog and digital communications systems. The flexibility allow customer to customize its own special standard according. With the Satellite Signal option, the T3260A transform to a Satellite vector signal generator. For its dual independent signal generator output, it can simulate world command satellite signal such as BeiDou/ GPS/GLONASS/GALILEO and interference signal
