May 3, 2014. VTI Instruments has announced the introduction of its CMX18—a high-power hybrid PXIe chassis designed for ATE test systems. Leveraging the company's experience in designing and providing high-power VXI mainframes for ATE, the CMX provides extensive built-in health monitoring, giving the user feedback of temperature, fan speed (airflow), and supply-line monitoring information to help reduce the mean time to repair (MTTR).
The chassis can shut down the system in real-time if a fault condition occurs. Cooling has been designed to satisfy ATE rack cooling conventions, pulling air from the sides and bottom, evenly distributing it, and exhausting it to the rear. Rack-mount kits enable recessing of the mainframe to accommodate cable harnesses as well as seamless integration with mass interconnect systems.
“The performance of our CMX18 is unmatched,” said Tom Sarfi, director of modular instrumentation products. “Not only is it a true 4U rugged construction mainframe with an extended operating temperature range between -10 to +55°C, but we have also designed in an advanced PCIe switch fabric, for non-transparent switching and a partionable architecture for true deterministic slot-slot communications. This allows multiple test engines to be housed within one mainframe, allowing for parallel tests, thus improving product test throughput.”
Designed with a 1000 Watt power supply, the CMX18 operates at 91% power efficiency, easily satisfying the most power hungry application requirements. For multichannel data acquisition applications, when combined with the EMX-2500 LXI-PXIe interface, the CMX18 provides IEEE-1588 time-source distribution to all slots, providing for a time-stamped deterministic multichannel solution. The clock synchronization between a single master instrument and multiple slaves is achieved using standard Ethernet cables, resulting in simplified installation and maintenance.
