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 make it ideal for housing the latest generation of high-performance VXIbus instruments, such as high-power digital test instruments.

Unprecedented Power and Speed
The 1263HPf high-power mainframe is the first to take advantage of the power and speed delivered by the latest revision to the VXIbus specification.

The new more powerful 5-row backplane connectors replace the traditional 3-row type, providing higher transfer speeds and higher power to each slot.

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 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
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.

1263 Series
The 1263 series also includes the high-power, rear-maintainable 1263HPr and medium-power, front-maintainable 1263MPf.
