Comunicación entre el instrumento y el conductor

Comunicarse con instrumentos mediante controladores de instrumentos

Es necesario crear un objeto de interfaz, por ejemplo gpib o i2c, para comunicarse con los instrumentos, como se describe en muchas de las secciones de la documentación. También puede crear un objeto de dispositivo que le permita configurar y consultar un instrumento sin conocer su conjunto de comandos. Consulte Creating and Connecting Device Objects para obtener más información sobre el uso de objetos de dispositivo.

Temas

Creating and Connecting Device Objects
Includes the general procedure for the creation and use of device objects.
Communicating with Instruments
Configuring and exchanging data through device objects.
Device Groups
Obtaining and using group device properties.
Device Objects
Device objects allow you to configure and query an instrument without knowledge of its command set. The low-level communication is performed through a MATLAB^® instrument driver.
