Input impedance, analog input connectors, over-voltage protection, and dedicated mechanical design match the attenuator board flawlessly with the PXIe-9848. The attenuator delivers the perfect solution to measurement range expansion in the PXI system.
Application: Power Supply Unit Testing
During manufacture of power supply units, quality validation is required before shipping. Critical technical parameters include rising time, overshoot, and turn-on delay, with analysis thereof ideally conducted directly on the processing line. Conventionally, manufacturers have employed complicated power measurement instrumentation for these duties, with the benefits of precise measurement for all of power parameters, but at the expense of cost and space required. As well, in most cases, only a single unit can be tested at a time, an extreme impediment to efficiency and potential production bottleneck. By taking advantage of the inherent modularity of the PXI interface, however, power supply unit test systems can quickly adapt to changing measurement requirements with increases in performance and speed of units to be tested.
ADLINK Solution: PXIe-9848H: 8-CH 14-Bit 100 MS/s High-Speed PXI Express Digitizer w/ Attenuator
ADLINK??s PXIe-9848H 8-channel, 14-bit, 100 MS/s digitizer, featuring both high-accuracy measurement results and high-dynamic performance, is uniquely suited to application in Power Supply Unit testing operations. The 14-Bit capability can detect low ripple noise up to µV grade, and the 100MS/s & 100MHz high-bandwidth can sample µs grade rapid vibrational rise times.
