The RE103 discussion under Test Procedures in Appendix A.5.18 (5.18), MIL-STD 461F, is somewhat puzzling to me. It states:
"Test procedures: Since the test procedure measures emissions radiating from an antenna connected to a controlled impedance, shielded, transmission line, the measurement results should be largely independent of the test setup configuration. Therefore, it is not necessary to maintain the basic test setup described in the main body of this standard." Except for the receive antenna, the statement is quite similar to the corresponding statement in A.5.6 (5.6) CE106: "Test procedures: Since the test procedures measure emissions present on a controlled impedance, shielded, transmission line, the measurement results should be largely independent of the test setup configuration. Therefore, it is not necessary to maintain the basic test setup described in the main body of this standard." It is logical to reason that there is no need to "maintain the basic test setup" when conducting CE106. There are no antenna's in the setup. Therefore chamber reflections are not an issue, so we expect the results to be independent from that standpoint. So I am apparently missing something. How could RE103 emissions measured in either a anechoic chamber or OATS be independent of the test setup configuration? What is really meant by "the basic test setup described in the main body of this standard."? And yes, I've checked 461E, which reads essentially the same. Charles D.
