VISA-Schnittstelle
Sie können die VISA-Schnittstelle mit vielen verschiedenen Schnittstellentypen verwenden, beispielsweise TCP/IP, USB, GPIB und anderen. Sie erstellen ein visadev-Objekt mit Argumenten, die den Typ der Schnittstelle bestimmen, über die Sie kommunizieren. Für ein VISA-GPIB-Objekt verwendet die Funktion visadev beispielsweise eine VISA-Ressourcenzeichenfolge, die den Boardindex und die Adresse enthält.
