E1 et E2 semblent intervertis dans FSW 3.3.0.1

Description
Test fait sur EM1 avec FSW 3.3.0.1:
On injecte un signal uniquement sur E1 :
Résultat attendu : avec les nouvelles matrices de calibration/chgt de repère on devrait observé du signal sur les ASM E1 ET E2
Résultat observé : on ne voit du signale que sur E2, rien sur E1
On injecte un signal uniquement sur E2 :
Résultat attendu : avec les nouvelles matrices de calibration/chgt de repère on devrait observé du signal sur les ASM E1 uniquement
Résultat observé : on voit du signal sur E2 ET E1
On dirait que les canaux E1 et E2 sont intervertis dans le traitement du FSW.
On a fait le test avec 3.2.0.24 et on voit bien E1 et E2 réagir comme attendu.
A confirmer avec des matrices unitaires.

Test fait avec matrices unitaires pour retrouver le comportement de FSW 3.2.0.24.
Il y a toujours un truc qui ne va pas,on dirait que l'injection exclusive sur E1 ou E2 produit du signal sur E1 ET E2.
Mais il faut d'abord que je puisse faire un KCOEFF_DUMP pour être sûr que mes matrices unitaires sont bien prises en comptes. Attente résolution #3908 .

Test refait en 3.3.0.7 avec une sinusoide 3Khz :
AVEC MATRICES UNITAIRES KCOEFF : même comportement qu'en 3.2.0.24 = comportement attendu ==> quand on injecte sur E1 on ne voit le signal qu'en E1, quand on injecte sur E2 on ne voit du signal que sur E2
AVEC KCOEFF par défaut : je confirme qu'on observe l'inverse de ce qui est attendu :
On injecte un signal uniquement sur E1 :
Résultat attendu : avec les nouvelles matrices de calibration/chgt de repère on devrait observé du signal sur les ASM E1 ET E2
Résultat observé : on ne voit du signale que sur E2, rien sur E1
On injecte un signal uniquement sur E2 :
Résultat attendu : avec les nouvelles matrices de calibration/chgt de repère on devrait observé du signal sur les ASM E1 uniquement
Résultat observé : on voit du signal sur E2 ET E1
CONCLUSION :
Il semble que le problème viennent des valeurs des KCOEFF par défaut car avec les matrices unitaires il n'y a pas d'inversion entre E1 et E2.
Il faudrait revalider que les KCOEFF par défaut sont bien ceux qui sont censés produire le comportement attendu.
Je réattribue à Thomas.

Bruno, est ce que tu peux télécharger ici le fichier des kcoeffients que tu as utilisés ?

Je n'ai pas utilisé de fichier pour charger les KCOEFF, j'ai juste démarrer LFR avec ses KCOEFF par défaut. Voici le code d'Alexis qui charge les KCOEFF (matrices clés+matrices interpolées) :
Je vais voir si j'ai fait un dump et je te l'envoie histoire que tu n'aies que les matrices clés (36*32)

mea kulpa, je me suis trompé sur ce qu'on attendait!
On injecte un signal uniquement sur E1 (donc le champ électric est perpendiculaire à ANT23, donc // à Z car cette antenne est // à Y) :
Résultat attendu : avec les nouvelles matrices de calibration/chgt de repère de [ANT12, ANT23] vers [Y, Z] on devrait observé du signal que sur les ASM E2 (// à Z)
Résultat observé : on ne voit du signale que sur E2, rien sur E1 => OK
On injecte un signal uniquement sur E2 (donc le champ électric est perpendiculaire à ANT12, donc en biais par rapport à Y et Z) :
Résultat attendu : avec les nouvelles matrices de calibration/chgt de repère de [ANT12, ANT23] vers [Y, Z] on devrait observé du signal sur les ASM E1 et E2
Résultat observé : on voit du signal sur E2 ET E1 = OK
Conclusion du moment: nous n'avons en première analyse aucune contradiction 
Bruno, tu peux comme on a dit faire la mesure avec une sinusoïde pour les deux config de base envisagées (matrices unitaires et matrices par défault) et m'envoyer les fichiers ASM (et BP2 et BP1 dans la foulée) ...

Ok super ! Merci. Je cloture. Je fais les jeux de tests demandés dès demain. J'ai vérifié hier : je peux te faire un jeu avec le même signal injecté sur E1, E2, B1, B2 et B3 en même temps .
