The Rigol DSG821 RF signal generator is the latest addition to the successful DSG800 series from Rigol. The DSG821 has a bandwidth up to 2.1 GHz and has a maximum output power of +20dBm. The series has an amplitude accuracy of less than 0.5dB and a frequency resolution of no less than 0.01 Hz.
RF signal generators offer the possibility to modulate AM/FM/ØM, but also pulse modulations (optional). In addition to the analog output, the DSG821 also features USB-Host, USB Device and LAN interfaces. This makes it possible to remotely control and program the RF signal generator.
