Bending Test Comparison Data for MWX312 and a Conventional Cable

The connector on one end of test cable (MXW312-00500AMSAMS, measuring 500 mm in length and with SMA (m) connectors on both ends) was fixed in place. The connector on the other end was moved in the sequence a → b → c, after which initial insertion loss and return loss values were compared to those after the test.
