Astronics Test Systems Inc. Racal Instruments™ High-Power, Front-Maintainable VXI 4.0* Mainframe The Racal Instruments™ 1263HPf VXI 4.0 high-power 13-slot mainframe allows you to leverage the speed and power of the newest VXI standard. The high power and cooling capability makes it ideal for housing the latest generation of high-performance VXIbus instruments, such as high-power digital test instruments. Product Information • Front-removable power supply tray and fan tray Unprecedented Power and Speed • LAN monitoring of voltage, temperature, and fan speed • 3.8 kW of usable power delivered to VXI 3.0 or 4.0 compatible modules • VXI 4.0 backplane for ultra-high speed and power • Automatic fan speed control for quiet operation The 1263HPf high-power mainframe is the rst to take advantage of the power and speed delivered by the latest revision to the VXIbus specication. The new more powerful 5-row backplane connectors replace the traditional 3-row type, providing higher transfer speeds and higher power to each slot. The outlet temperature of each slot, fan speed, ambient temperature, and rail voltages are all monitored and tied to programmable alarms that report out-of-tolerance conditions via a discrete fault indicator or over the LAN. VXI 4.0 Support Safe Operation The 1263HPf delivers a total of 4.0 kW to 13 VXI 4.0 slots. This power level requires adequate cooling and monitoring to ensure reliable system operation, especially when modules with high internal power dissipation are used.

Substantial cooling is provided with 1200 CFM of cooling air directed from the front and side air inlets to the module slots and circulated out the top and rear of the mainframe. The 1263HPf backplane fully supports all VXI 4.0 features, including parallel transfer up to 320 MB/s with 2eSST protocol, which was created to handle high-speed transfer rates. New 5-row P1 and P2 connectors provide more power and speed while maintaining compatibility with pre-existing VXI applications.
