Interfaz GPIB

Comuníquese con los instrumentos mediante la interfaz VISA-GPIB.

GPIB es una interfaz estandarizada que permite conectar y controlar múltiples dispositivos de diversos fabricantes. La comunicación se establece a través de un objeto VISA-GPIB, visadev, que se crea en el área de trabajo MATLAB^®. Para obtener información sobre cómo crear el objeto VISA-GPIB, consulte Get Started with GPIB Interface.

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