Rigol DNA5000 and DNA6000 Series vector network analyzers support RF and microwave analysis across a frequency range from 5kHz to 26.5GHz. Available in 2-port and 4-port configurations, the instruments support testing of passive components including filters, antennas, cables, dielectric materials, and high-speed interconnects. The analyzers offer dynamic range up to 127dB and low trace noise to support characterization of high-rejection devices and stable measurement performance. Fixture removal and de-embedding functions allow measurement correction for test fixtures, adapters, and cables, enabling direct S-parameter analysis of the device under test. Built-in analysis tools include limit testing, standing wave ratio (SWR) measurement, Smith chart display, and time domain reflectometry (TDR). An integrated calibration wizard guides setup procedures to support measurement repeatability across laboratory and production environments. The instruments feature a touchscreen interface and support HDMI, LAN, USB, and GPIB connectivity for integration with automated test systems. The compact DNA5000 Series targets bench-space-constrained environments, while the benchtop DNA6000 Series supports long-duration testing and automated production test configurations.
