Rigol DSG821A RF signal generator
Details
The Rigol DSG821A RF signal generator is the latest addition to the successful DSG800 series from Rigol. The DSG821A 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.The difference between the DSG821A and DSG821 is that the DSG821A comes with IQ modulation.
RF signal generators offer the possibility to modulate AM/FM/ØM, but also pulse modulations (optional). In addition to the analogue output, the DSG821A also features USB-Host, USB Device and LAN interfaces. This makes it possible to remotely control and program the RF signal generator.
