RACAL INSTRUMENTS 1261B High-Performance VXI Chassis Introduction Modern test environments cannot tolerate downtime. The mainframe must keep running continuously. The 1261B takes advantage of our years of experience as a leading VXI mainframe manufacturer to deliver maximum performance and reliability at a price that is competitive with low-end units Power The 1261B power supply features an advanced design that delivers Highest Cooling Level of abundant power with a minimum of ripple and noise. The power supply any General-purpose VXI plugs directly into the backplane for the best possible power delivery. Mainframe High dynamic current ensures crisp waveforms and accurate measurements. Fault-Tolerant Cooling System Cooling Two Choices of Our fourth generation, 13-slot mainframe incorporates many unique technological advances to deliver the most cooling and highest VXI-8 Monitoring Options curves of any general-purpose VXI mainframe. This ensures the lowest Independently Pluggable temperature rise in your VXI modules for the most reliable system Power Supply and Fan operation possible. The mainframe features a pressurized plenum system Assemblies for even airflow distribution from front to back and side to side. Unique, molded cardguides direct airflow through installed modules rather than Monitoring Option is between them. Snap-on covers divert airflow away from unused slots. Independently Powered and Needs No VXI Slots The 1261B features a fault-tolerant cooling system using a rear-pluggable assembly with three fans. If a fan failure should occur, the two remaining 925 W of Total Usable fans still deliver a high level of cooling, preserving your VXI module Power @ 55° C investment. Basic 1261B units include a HI/LO cooling switch to minimize audible noise during system development and maximize the reliability of fielded systems. Units equipped with a system monitor feature a variable speed cooling system that adjusts fan speed based upon the worst slot temperature rise. This ensures ample cooling while minimizing audible noise. A rear switch permits maximum cooling to be selected, if desired, to achieve maximum reliability of fielded systems 7U and 9U Versions The 1261B mainframes are available in two sizes, 7U and 9U. The 9U mainframes are ideal for rackmount applications. They draw in air from the sides of the mainframe and exhaust out the rear to minimize rack chimney effects . They also include a 2.25 deep cable tray. The 7U mainframes are ideal for benchtop and space-limited applications. They draw in air from the rear of the mainframe and exhaust out the top.
