Amplitude (dB)Simple <strong>Reflection</strong> Test in Chamber• A simple reflection test involvescomparing 0° and 180° Phi cuts• For a correctly alignedmeasurement system, thedifferences in the patterns aredue to the range reflections• Subtraction of the two patternsgives a preliminary estimate ofexpected error signal level• Chamber test result at 10 GHzon the DLP• Shows relatively good result ofabout -40 dB error level0-5-10-15-20-25-30-35-40-45-50-55-60Scattering Estimated <strong>for</strong> File TECOM_509H_TECOM 495H_103.NSIComparing 0 and 180 Phi Cuts at Freq = 10 GHzPhi=0 Phi=180 SCAT.
