The Agilent E8491B 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 E8491B is a cost-effective choice for test applications when used with the E84XX mainframe series. The E8491B is well suited for data acquisition applications moving large blocks of data.
The E8491B is a high-speed C-size device with Resource Manager and Slot 0 capability. Its logical address is 0, therefore it is always the mainframe's Resource Manager and is typically installed in mainframe Slot 0. The high speed is accomplished, in part, through the use of small signals (200 mV) that are transmitted differentially over the twisted-pair wire set with controlled-impedance characteristics. The differential signal provides high-noise immunity.
