Rigol VSWR-DSA800 option (used together with a VSWR bridge and Rigol DSA800 series spectrum analyser with built-in tracking generator) enables the functionality within a Rigol DSA800 series spectrum analyser that allows VSWR / return loss / S11 / S22 measurements to be made.
Press ‘Meas’ on the front panel and then press ‘VSWR’ to enable the VSWR measurement function. The screen is divided into two windows with the upper window (the basic measurement window) displaying the sweep trace and the lower window displaying the measurement wizard and measurement results. The measurement wizard will guide you through the open circuit calibration process.
Each licence contains a unique product key. The product key is used to generate a software licence code that must be entered into your instrument. To generate a Rigol software licence code using your Rigol product key, please see HERE. Installed software licence codes are permanent – They are unaffected by Rigol firmware updates.
