Get Started with GPIB Interface
You can communicate with GPIB instruments in MATLAB® by using the VISA-GPIB interface.
Install Required Drivers
In order to use the VISA-GPIB interface, you must have the required drivers installed for both GPIB and VISA. The VISA-GPIB interface is supported on Windows® 10 and not available for macOS or Linux.
The following table shows the minimum GPIB and VISA driver versions you must have. You must have one of the following GPIB drivers and its corresponding VISA driver both installed.
|Minimum GPIB driver||Minimum VISA driver|
|Keysight™ IO Libraries version 18.1.24715.0 (Keysight Connection Expert 2019)||Keysight IO Libraries version 18.1.24715.0 (Keysight Connection Expert 2019)|
|ICS 488.2v4 Adaptor version 4.0|
|ADLINK ADL-GPIB version 20.01.0|
|NI-488.2 Adaptor v2.8|
National Instruments® NI-VISA version 19.5
|MCC GPIB 488.2 Library v2.3|
Create VISA-GPIB Object
Create a VISA-GPIB object with the
visadev function. Each VISA-GPIB object is associated with:
A GPIB controller installed in your computer
An instrument with a GPIB interface
visadev requires the resource name or alias as an input. The
resource name consists of the GPIB board index, the instrument primary address, and
the instrument secondary address. You can find the VISA-GPIB resource name or alias
for a given instrument with the configuration tool provided by your vendor or with
visadevlist function. Define the alias using your VISA vendor
The VISA-GPIB resource name has the format
For example, use the VISA-GPIB interface to connect to a National Instruments controller with board index 0 and a Tektronix® TDS1002 digital oscilloscope with primary address 1 and secondary address 0.
visagpib = visadev("GPIB0::1::0::INSTR")
visagpib = GPIB with properties: ResourceName: "GPIB0::1::0::INSTR" Alias: "OSCOPE_2CH" Vendor: "TEKTRONIX" Model: "TDS 1002" BoardIndex: 0 PrimaryAddress: 1 SecondaryAddress: 0 NumBytesAvailable: 0 Show all properties, functions
