ABSTRACT:
Method and apparatus for making phase stable measurements of charateristics of microwave antennas and other devices utilizing an optical transmission path as a phase stable reference in order to identify phase errors along a radio frequency transmission path induced by flexing of a radio frequency transmitting cable as the antenna probe or antenna under test is moved in the course of testing. Similar apparatus and techniques are described for use with a harmonic mixer to gather receiver data which is free of phase errors caused by movement of the antenna.
