The 60N50 SWR Bridge is a precision, high directivity measurement component ideal for SWR and return loss measurements. The 60N50 is used with other test instruments for making fixed and swept frequency return loss (SWR) measurements over a wide range of radio frequencies. Return loss measurements are made to check the performance of systems, subsystems, and microwave components such as amplifiers, directional couplers, attenuators, filters, splitters, and terminations.
