Test und Messung
Generieren Sie Wellenformen und verwenden Sie quantitative Tools zur Messung der Systemleistung. Verwenden Sie grafische Hilfsprogramme wie Konstellations- und Augendiagramme zur Visualisierung der Effekte verschiedener Störungen und Korrekturen.
Die unterstützten Dateiformate zur Verarbeitung erfasster Signale umfassen binäre Basisband-Signalformate und NI™ TDMS-Formate (Technical Data Management Solution). Sie können Daten in Tabellen oder Timetables übertragen, indem Sie TDMS-Dateien einzeln oder Sammlungen an TDMS-Dateien simultan auslesen.
