Firmware

Version 2.40 of the control firmware in the SR2500/SR2500 digital test subsystems includes SmartLEARn to reduce test configuration load time. With this firmware, when the SR2500/SR5000 is learning the test configuration only the pins of the active I/O modules are read. When later outputting the saved test program to the VXI timing/control module, only the programming for the active modules is transferred. This greatly reduces test configuration time. In certain instances, depending on the number of unused modules in the test setup, load time can be reduced to as little as 14% of the time that would otherwise be required without the SmartLEARn feature.

Pump

A high-flow diaphragm pump delivers up to 170 gpm without the air motor stalling and icing problems that are inherent with pumps of this type. A Simul-Shift^TM air valving design virtually eliminates pump stall-out under any condition, including low-air inlet pressures. By directing cold and wet exhaust air away from the pump's air motor section, a "Quick Dump" design provides high-flow fluid handling an ice-free future. Bolted construction reduces the possibility of material spillage/contamination, while providing a positive, hard-joint diaphragm seal and much easier reassembly.
