Interfaz GPIB

Comunicarse con los instrumentos mediante la interfaz VISA-GPIB

GPIB es una interfaz estandarizada que le permite conectar y controlar múltiples dispositivos de distintos proveedores. La comunicación se establece a través de un objeto VISA-GPIB, visadev, que se crea en el espacio de trabajo MATLAB^®. Para obtener información sobre la creación del objeto VISA-GPIB, consulte Get Started with GPIB Interface.

Puede escribir y leer datos binarios y de texto. Para ver ejemplos de ambos, consulte Write and Read GPIB Data.
