The DSG821A is a 2.1 GHz RF generator from Rigol. DSG800 series RF signal generator provides all-round modulation plans. It provides standard AM/FM/ØM functions as well as optional pulse modulation function, and pulse train generator. Besides, DSG821A and DSG836A are equipped with a standard configuration of I/Q modulation function. All the modulation functions support both external and internal sources. Besides, to fulfill the application requirements of the production lines, severe test verifications are performed on DSG800 during the design and production phases to ensure its stability and reliability. DSG800 provides clear panel layout and is easy-to-operate. It can output stable, accurate and pure signals.
