The 8741A Reflection Test Unit is a wideband reflectometer designed for use in the 0.11 to 2.0 GHz range with the model 8410A Network Analyzer (not included), and the 8411A Harmonic Frequency Converter (not included). 

A variable reference plane allows changes in treference-plane position, as well as phase-balanc for swept or spot frequency reflection or impedance tests.
