The Wiltron 97S50 is a precision SWR Autotester engineered for characterizing return loss across microwave components and systems. It integrates a high directivity bridge, detector, low reflection test port, and precision reference termination to deliver accurate fixed-frequency and swept-frequency measurements from 10 MHz to 18 GHz. The instrument operates with 38 dB directivity and WSMA Male connectors terminated at 50 Ohms, making it suitable for laboratory and production environments where return loss verification demands high accuracy. Directivity can be extended to 60 dB using air line techniques and optional accessories. The detector exhibits negative polarity and handles a maximum input power of 0.5 watts (+27 dBm).
