In addition, Python can be used to directly access
Python can be used to call functions from a The VISA specification has explicit bindings to Visual Basic, C, and G Limited to certain interface devices, such as the vendor’s GPIB card. Work together with arbitrary peripherical devices, although they may be Of vendors offer VISA libraries, partly with free download.
Today VISA is implemented on all significant operating systems. Instrumentation systems comprising GPIB, VXI, PXI, Serial, Ethernet, and/or VISA is a standard for configuring, programming, and troubleshooting In order to ease this unfortunate situation, the Virtual Instrument SoftwareĪrchitecture (VISA) specification was defined in the middle of the 90ies. To use, you have to find libraries that support both your device and its bus There are manyĭifferent protocols, sent over many different interfaces and bus systems The programming of measurement instruments can be real pain. National Instruments, Agilent, Tektronix, (That’s the whole program really!) It works on Windows, Linux and Mac open_resource ( 'GPIB0::12::INSTR' ) > print ( inst. One side of the National Instruments GPIB-USB-A connector should be connected to GPIB instruments, while the USB side of the controller should be connected to the USB port of the user’s personal computer.> import pyvisa > rm = pyvisa. The connection of the GPIB-USB-A Controller is easy and convenient to handle. The controller comes with an IEEE 488 standard 24-pin IEEE-488 I/O connector for GPIB and a USB standard series A plug for the USB I/O connector. The controller is compatible with USB 1.1. The compatible driver software for the NI GPIB-USB-A is NI-488.2. The software recommended for this controller includes LabVIEW, LabWindows/CVI, and Measurement Studio.
The operating system best suited for this controller is Windows. The data transfer rate for the National Instruments GPIB-USB-A is 650 Kbytes/s. The NI GPIB-USB-A can be used either with a laptop or with desktop applications. The compact and small size make this controller a great option for portable applications. The GPIB-USB-A does not require the computer to restart when connected, ensuring a quick installation. The NI GPIB-USB-A provides easy plug and play connectivity, so the operating system can recognize the controller as soon as the user connects it with his/her computer. The IEEE-488 version 2 controller can control as many as 14 programmable devices through the GPIB interface. This Controller can convert a personal computer to an IEEE-488.2 controller integrated with full functionality to control any GPIB device. The developer of the GPIB-USB-A Controller is National Instruments. The GPIB-USB-A is a GPIB Controller designed to communicate between GPIB devices and personal computers with Universal Serial Bus ports. National Instruments GPIB-USB-A GPIB Controller
