Keysight TECHNOLOGIES N7954AWith the Keysight Technologies, Advanced Power System (APS) N7954A 1 kW system power supplies, you get a new level of power supply performance. The Keysight N7954A was designed with VersaPower architecture to help you overcome your toughest power test challenges by delivering industry-leading specifications and innovative features in an integrated solution for today’s advanced ATE power testing needs.Keysight N7954A utilizes the advance architecture of VersaPower which uses cutting- edge technology to deliver industry leading performance and innovative capabilities not typically found in a switching power supply design. The Keysight N7954A VersaPower architecture delivers the fastest and most accurate integrated power system. Accelerate test-system throughput with industry-leading speed. With the Keysight N7954A you can capture your DUT’s cur profile with accurate measurements, reduce your ATE development time and cost with highly integrated capabilitiesShaving seconds or even milliseconds off a test time can lead to significant savings for high-volume manufacturers, making throughput gains a never-ending quest for test system designers. The Keysight N7954A is a valuable tool for increasing throughput. The N7954A provides a number of industry-leading specifications and innovative features that can help you achieve significant throughput gains in your testing.The Keysight N7954A provides simultaneous voltage and cur measurement capabilities that deliver an astonishingly high accuracy and resolution. Use the Keysight N7954A to make measurements using two main modes: averaged or digitized. In average mode, the N7954A delivers high accuracy DMM-quality voltage and cur measurements. The digitizing capability of the Keysight N7954A allows you to capture dynamic cur or voltage profiles at much higher resolution than an Oscilloscope.Keysight N7954A key features and specifications:
