Agilent / Keysight E9850A VXI Pentium PC Controller, 450 MHz, Windows 95/NT

The E9850A is a C-size, 2-slot VXI embedded PC controller that integrates a 450 MHz Intel Pentium II processor directly into Keysight VXI mainframes. Designed for measurement automation and complex data processing in VXI-based test systems, this message-based controller runs Windows 95 or Windows NT 4.0 and provides field-upgradeable architecture with standard Slot 1 processor compatibility.
