  The wire method is a more rapid and less costly method to measure impedances
of RF components compared to methods using a beam. A setup using a single
displaced wire to excite and measure transverse resonant modes in accelerating
structures for the Next Linear Collider/ Japanese Linear Collider (NLC/JLC) has
been built. The RF signal is coupled into and out of the structure using two
matching sections with a broadband frequency from 11 to 18 GHz. Their
contribution to the scattering parameter is minimized by a calibration
technique. A standing wave structure has been measured. Difficulties in
accurately predicting the modal loss factors were encountered related to the
approximations made and to experimental issues. The measurements are presented
and comparisons with simulations are made.
