The Wiltron 560-98S50 is an SWR autotester engineered for broadband microwave return loss measurements from 10 MHz to 18 GHz. It combines a high-directivity bridge, integrated detector, low-reflection test port, and precision reference termination into a single instrument. This autotester operates as a front-end module for scalar network analyzers including the Wiltron 560A and 56100A, delivering both fixed-frequency and swept-frequency SWR characterization. The 560-98S50 achieves 35 dB directivity with frequency sensitivity of 0.014 dB typical across its operating range, making it suitable for rapid performance verification of RF and microwave components.
