The Rigol DSG821 is an RF signal generator covering 9 kHz to 2.1 GHz, engineered for research, development, and production testing. It delivers stable, accurate signal generation with output amplitude from -110 dBm to +13 dBm (leveled), or up to +20 dBm unleveled. Phase noise performance reaches <-112 dBc/Hz typical, with amplitude accuracy of ≤0.5 dB. The instrument combines high frequency resolution (0.01 Hz), flexible modulation capabilities, and a compact 2U form factor ideal for bench and rack deployments.
