GPIB 接口

使用 VISA-GPIB 接口与仪器通信

GPIB 是一种标准化接口，允许您连接和控制来自不同供应商的多个设备。通信是通过您在 MATLAB^® 工作区中创建的 VISA-GPIB 对象 visadev 建立的。有关创建 VISA-GPIB 对象的信息，请参阅 Get Started with GPIB Interface。

您可以写入和读取二进制数据和文本数据。有关两者的示例，请参阅 Write and Read GPIB Data。

函数

`visadevlist`	List available VISA resources
`visadev`	Create connection to device using VISA
`configureTerminator`	Set terminator for ASCII string communication with VISA resource
`visastatus`	Check status of VISA resource
`visatrigger`	Send trigger to GPIB or VXI instruments
`visadevfind`	Find VISA device connections (自 R2024a 起)

`read`	Read data from VISA resource
`readline`	Read line of ASCII string data from VISA resource
`readbinblock`	Read one binblock of data from VISA resource
`write`	Write data to VISA resource
`writeline`	Write line of ASCII data to VISA resource
`writebinblock`	Write one binblock of data to VISA resource
`writeread`	Write command to VISA resource and read response
`flush`	Clear buffers for communication with VISA resource

Get Started with GPIB Interface
Establish a connection between MATLAB and your instrument using the VISA-GPIB interface.
Write and Read GPIB Data
Write and read both text and binary data over the VISA-GPIB interface.
Send Trigger to Instrument
Send the trigger command to your VISA resource.
Execute Serial Polls
Execute a serial poll to check the status of your VISA resource.
GPIB Overview
Basic features of the General Purpose Interface Bus (GPIB).
Transition Your Code to VISA-GPIB Interface
Connect to a GPIB instrument using visadev instead of gpib.
