The Rigol DSA832-TG is a 3.2 GHz spectrum analyzer with integrated tracking generator for RF stimulus-response measurements and component characterization. The instrument spans 9 kHz to 3.2 GHz with a compact footprint suitable for benchtop and field deployment. An 8-inch LCD display (800×480 pixels) delivers clear signal visualization across the full operating range.
