In order to validate the millimeter wave design procedure, the EL mock-up has been constructed and the low power test has been carried out by using mW-level low power RF oscillators. The test has been carried out with critical four edged beams instead of all eight beams in the upper waveguide unit. The measured data has been compared with design at several important locations in the launcher and after the launcher exit with steering mirror angle changed. The comparison of the measured beams propagation and the design shows good agreement for the beam sizes and the beam orientation performance. The quantitative evaluations has been carried out and the design procedure's reasonability has been confirmed.
