The Rigol VB1040 is a 50 Ω VSWR bridge that measures S11 and S22 parameters across 800 MHz to 4 GHz, enabling characterization of filters, amplifiers, mixers, and antennas. Designed for direct integration with Rigol spectrum analyzers equipped with a tracking generator, it eliminates external cabling to improve measurement accuracy and convenience.

– Key Features
• Three-port configuration: IN (signal source), OUT (analyzer RF input), DUT (device under test)
• Minimal insertion loss preserves signal integrity during reflection measurements
• Directivity performance ensures accurate return loss and reflection coefficient determination
• Compact form factor with direct front-panel mounting to compatible Rigol analyzers
• Operating range covers UHF through C-band applications
– Typical Applications
• S11 parameter measurement (return loss, reflection coefficient) for RF components
• VSWR and resonant frequency characterization of antennas
• Filter, amplifier, and mixer impedance and loss evaluation
• Network efficiency verification and signal transmission validation
– Compatibility & Integration
The VB1040 operates with Rigol DSA800 and RSA series spectrum analyzers. A tracking generator (TG option) is required for operation. The included VSWR-DSA800 measurement software is compatible with DSA800 series analyzers only; DSA1000 series compatibility is not supported.
