What are GPIB and VISA?

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 in the 1960s, and later became an industry standard known as IEEE-488. GPIB allows you to send commands and receive data from your instruments using a parallel data transfer protocol.

VISA stands for Virtual Instrument Software Architecture, which is a standard for software that communicates with instruments using various interfaces, such as GPIB, Ethernet, serial, USB, and others. VISA was developed by National Instruments and other instrument vendors in the 1990s, and later became an industry standard known as IVI Foundation. VISA provides a common API (Application Programming Interface) that simplifies the programming of instrument control applications.

How to Use GPIB Card Driver and VISA 3.2.8 for Instrument Control?

To use the GPIB card driver and VISA 3.2.8 for instrument control, you will need to follow these steps:

Make sure that your GPIB card is properly installed in your computer and that your instruments are connected to it using a GPIB cable.

Launch LabVIEW or another programming language that supports VISA.

Create a new project or open an existing one.

Add a new VI (Virtual Instrument) or open an existing one.

Use the VISA functions or subVIs to communicate with your instruments using GPIB commands.

Run your VI or program and observe the results.

For example, if you want to measure the voltage of a multimeter using LabVIEW and VISA, you can use the following steps:

Create a new VI or open an existing one.

Add a VISA Resource Name control to the front panel.

Add a Numeric Indicator control to the front panel.

Add a VISA Configure Serial Port VI to the block diagram.

Add a VISA Write VI to the block diagram.

Add a VISA Read VI to the block diagram.

Add a String To Number VI to the block diagram.

Connect the wires as shown in the figure below:

Enter the resource name of your multimeter in the VISA Resource Name control. For example, if your multimeter is connected to GPIB address 1, you can enter "GPIB0::1::INSTR".

Enter the command that instructs your multimeter to measure voltage in DC mode in the VISA Write VI. For example, if your multimeter uses SCPI (Standard Commands for Programmable Instruments) syntax, you can enter "MEAS:VOLT:DC?"

Run your VI or program and observe the voltage value displayed in the Numeric Indicator control.
