The Rigol DSA815-TG is a spectrum analyzer with integrated tracking generator, engineered for RF signal measurement, component characterization, and scalar network analysis across 9 kHz to 1.5 GHz. The instrument combines a widescreen TFT-LCD display with a compact form factor suited to laboratory and field deployment. Its tracking generator extends from 150 kHz to 1.5 GHz at 0 dBm typical output, enabling transmission and reflection measurements without external sources. With 1 Hz frequency resolution, -130 dBm typical DANL, and temperature-compensated frequency reference, the DSA815-TG delivers the measurement accuracy and dynamic range required for filter verification, amplifier characterization, and component testing.
