The Rigol DSG3136B-IQ is an RF signal generator spanning 9 kHz to 13.6 GHz, engineered for research, development, and manufacturing environments requiring complex signal generation and precise modulation control. It delivers output amplitudes from -130 dBm to +27 dBm with amplitude accuracy better than 0.5 dB typical, supported by phase noise performance of -116 dBc/Hz @ 20 kHz offset typical. The instrument combines standard AM, FM, and phase modulation with optional I/Q modulation capabilities—internal bandwidth to 60 MHz with EVM < 0.7% typical, or external bandwidth to 240 MHz with EVM < 2% typical. Frequency sweep functionality includes triangle and ramp shapes in single or continuous modes, with 0.01 Hz resolution enabling fine-grained signal definition. Pulse modulation achieves on/off ratios exceeding 70 dB.
