仪器驱动通信

使用仪器驱动与仪器通信

您需要创建一个接口对象，例如 gpib 或 i2c，以便与仪器进行通信，如文档的许多部分所述。您还可以创建一个设备对象，使您无需了解其命令集即可配置和查询仪器。有关使用设备对象的详细信息，请参阅 Creating and Connecting Device Objects。

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.

Use an NI switch module with an NI digital multimeter to measure resistance.

Acquire the spectrum of a fluorescent light source from an Ocean Optics Spectrometer.
