| 1 | | Because channels C and D suddenly behaved weird (See coherence plot in Figure 1), a test was implemented after the end of the experiment: Two pairs of hybrid inputs were exchanged, the one that generates the A and B channels were exchanged with the one that generates the C and D channels. According to Figure 2, the problem found in the CD coherence plot, it is showed at the AB coherence plot now. A VSWR measure of the antenna showed that it has not problem, also ues lines were checked and they were ok. Only a part of the ATR was pending to check, |
