GPIB (通用接口总线)是在仪器类应用中广为使用的一种接口。今天，这种接口正受到USB和LAN等新兴标准的挑战，但GPIB创新性的发展，使其历久而弥新，市场地位难以撼动。本文介绍了GPIB面临的挑战和发展，以及用GPIB实现自动测试设备时应注意的事项，另外还介绍了用FPGA实现GPIB控制器的新方法。

This week, National Instruments unveiled a USB-to-GPIB controller that takes advantage of the high-speed USB 2.0 specification to offer transfer rates up to 1.8 Mbytes/s in standard IEEE 488.1 mode ...

With the 1105 USB-to-GPIB hub controller, any desktop or portable PC with a USB interface is converted into a full-function, IEEE-488.2-compatible bus controller.

内置硬件高精度频率计，配备LAN、USB、GPIB等多种通信接口及内建WebServer，SDG3000X实现多设备级联同步与远程控制，全面提升 测试效率 与操作便捷性。

The USB-3488A is both compact in size (3.2 x 2.4 x 1.1″) and lightweight (180 g) for greater portability. A built-in 2-meter USB cable supplies power and eliminates the need for external GPIB cables.

National Instruments began developing GPIB products in 1976 so engineers and scientists could control their instruments from desktop PCs regardless of vendor. Now, with the USB-GPIB-HS, NI is helping ...

Engineers and scientists now can use the latest USB standard, USB 2.0 high-speed, to control GPIB instruments at transfer rates of up to 8 MBytes/sec. The new National Instruments GPIB-USB-HS, claimed ...

The KUSB-488 transforms any computer with a USB port into a full-function, IEEE 488.2 controller that can control up to 14 programmable GPIB instruments. Designed by Keithley ...

To the lower right is a USB to GPIB converter board that [Steven Casagrande] developed. This one is PIC based, using the 18F4520 and an FTDI chip to handle the USB side of the equation.
