Anritsu FAQs
My Site Master has two N connectors on it. Do I need to calibrate both of them? Which one do I use?
The connector marked RF Out / Reflection is the only port that requires OSL calibration for Return Loss or / SWR measurements. Some Models like the S251C can make Insertion Gain or Insertion Loss measurements and the second port is included in an OSLIT (Open, Short, Load, Isolation, Through) calibration. Refer to the Users Guide for additional details.
