What is GPIB?
GPIB stands for General Purpose Interface Bus, which is a standard for connecting and controlling multiple instruments from a single computer. GPIB was originally developed by Hewlett-Packard (HP) in the 1960s and later standardized by the IEEE as IEEE-488. GPIB is also known as HPIB (HP Interface Bus) or IEC-625 (International Electrotechnical Commission).
GPIB allows you to send commands and receive data from instruments using a common syntax and protocol. GPIB also supports device identification, status reporting, error handling, and synchronization. GPIB can support up to 15 devices on a single bus, with a maximum data transfer rate of 8 MB/s.
What is VISA?
VISA stands for Virtual Instrument Software Architecture, which is a standard for configuring, programming, and troubleshooting instrumentation systems comprising GPIB, VXI, PXI, serial (RS232/RS485), Ethernet/LXI, and/or USB interfaces. VISA was developed by National Instruments (NI) in collaboration with other instrument vendors in the 1990s.
VISA provides a common API (Application Programming Interface) for accessing and controlling instruments from different vendors and platforms. VISA also provides utilities, low-level control features, and examples to help you create your application. VISA is compatible with various programming languages and environments, such as LabVIEW, LabWindows/CVI, C/C++, Visual Basic, Python, MATLAB, etc.
What is NI-VISA?
NI-VISA is the implementation of VISA by National Instruments. NI-VISA supports most NI hardware and software products, such as LabVIEW, NI-DAQmx, NI-488.2, etc. NI-VISA also supports instruments from other vendors that comply with the VISA standard.
NI-VISA includes the following components:
VISA Shared Components: These are the core libraries and utilities that provide the basic functionality of VISA.
VISA Run-Time Engine: This is the component that allows you to run applications that use VISA without installing the full development environment.
VISA Interactive Control (VISAIC): This is a utility that allows you to interactively communicate with instruments using VISA commands.
VISA Test Panels: These are utilities that allow you to test the communication and functionality of your instruments using graphical user interfaces.
VISA Configuration: This is a utility that allows you to configure the settings and properties of your VISA resources.
VISA Examples: These are sample programs that demonstrate how to use VISA in various programming languages and environments.
VISA Documentation: These are the manuals and help files that explain how to use VISA and its components.
What is NI-488.2?
NI-488.2 is the driver software that provides support for NI GPIB controllers and NI embedded controllers with GPIB ports. NI-488.2 implements the IEEE-488.2 standard, which defines the syntax and protocol for communicating with GPIB instruments. NI-488.2 also provides additional features, such as automatic instrument discovery, device configuration, error handling, performance optimization, etc.
NI-488.2 works in conjunction with NI-VISA to provide a high-level interface for accessing and controlling GPIB instruments. You can use NI-VISA functions or properties to communicate with GPIB instruments using NI-488.2 as the underlying layer.

How to Test GPIB Card Driver and VISA32
To test the GPIB card driver and VISA32, you need to follow these steps:
Connect your GPIB card to your computer and your GPIB instrument to your GPIB card using a GPIB cable.
Power on your GPIB instrument and make sure it is configured properly.
Open Measurement and Automation Explorer (MAX) from the Start menu or the NI Launcher.
Expand Devices and Interfaces and locate your GPIB card under NI-VISA Resources.
Select your GPIB card and click Scan for Instruments. MAX will attempt to identify your GPIB instrument and assign it a VISA resource name.
Select your GPIB instrument and click Test Panel. A test panel window will open, where you can send commands and receive responses from your instrument using VISA functions or properties.
Try sending some basic commands, such as *IDN? (identify), *RST (reset), or *TST? (self-test), and check the responses from your instrument. You can also use the buttons on the test panel window to perform common operations, such as read, write, trigger, etc.
If you can communicate with your instrument successfully, it means that your GPIB card driver and VISA32 are working properly. You can close the test panel window and MAX.
If you encounter any problems or errors during the test, refer to the [GPIB Instrument Control Tutorial] or the [NI-VISA Help] for troubleshooting tips and solutions.
