Interface VISA
Vous pouvez utiliser l'interface VISA avec différents types d'interfaces, telles que TCP/IP, USB, GPIB et autres. Vous créez un objet visadev en utilisant des arguments qui déterminent le type d'interface sur lequel vous communiquez. Par exemple, pour un objet VISA-GPIB, la fonction visadev prend une chaîne de ressources VISA qui inclut l'index et l'adresse de la carte.
