The Keysight E8491A IEEE-1394 PC link to VXI is a C-size, 1-slot, message-based VXI module, providing a direct connection from your PC to a VXI mainframe via the industry standard IEEE-1394 bus (FireWire). The Keysight E8491A is a cost effective choice for high-speed data acquisition applications moving large blocks of data. Users now have an affordable VXI solution for their test applications when the Keysight E8491A is used with Keysight' new E8400 mainframe series.

The Keysight E8491A includes a C-size VXI Slot 0 module and a 4.5-meter cable. It supports up to 16 mainframes with one PC. For restrictions on using I-SCPI, please refer to the Ordering Information Section below. Ease of configuration is achieved with automatic recognition of a new IEEE-1394-based device without powering down the PC, known as hot plug-in. The Keysight E8491A Opt. 001 includes an IEEE-1394/PCI card to install in your PC.

For multiple VXI mainframe systems, one Keysight E8491A is installed into each mainframe and these are interconnected via the cable in a daisy-chain or star configuration. This reduces the system cost further since an additional IEEE-1394/PCI card is not needed for each added mainframe. For more information about PCI 2.1 comliance, refer to the related information section below.

The Keysight E8491A includes clock and triggering capabilities, plus complete SICL/VISA I/O library software for the Windows 95 and Windows NT 32-bit environments. The interface also supports 32-bit Interpreted SCPI (I-SCPI).
