Hallo,
wie sieht die Formulierung fĂźr eine korrekte Quelle (hier E1) in
LT-Spice aus, bzw. ist meine Net-List aus LT-Spice so korrekt?
Kopiervorlage/ Ausgangslage

Ziel
----
"Vfield" und "Bloop" nach LT-Spice Ăźbertragen.
Um LT-Spice muckenfrei zum Laufen zu kriegen, wurde Bloop einfach durch
"E1" ersetzt.
Aber, ist die Ersetzung so korrekt?
