Evaluation Engineering: Is Your Accuracy Being Degraded? Nov 1, 2007 -- Test systems almost always involve multiple stimulus and measurement instruments for testing several points on the DUT. This implies the use of some sort of switching subsystem. If you think switches are simple and straightforward to select, this article may change your mind. Every switching system involves trade-offs... HTML PXI Online : Pin Electronics test and debug using PXI test station Summer 2002 -- See how the SMX2044 as an integral part of a production test station in semiconductor industry: Used for accurate voltage, current, resistance, capacitance, impedance, frequency, and leakage measurement, The SMX2044 is not just a standard DMM... Evaluation Engineering: The Art of Measuring Low Resistance Nov 1, 2006 -- Making accurate, stable, and repeatable resistance measurements is an art. There is plenty of technology involved, but the art is an important part, especially when you are measuring low resistance values. HTML PDF BestTest: How to select the right Switching Products Jan 16, 2006 -- Almost every test system includes some kind of switching module which routes signals to instruments to be measured and/or processed. There is no one product that can do it all. Various requirements imposed on the switching module may conflict with each other. This article will attempt to outline the various attributes and suggest ways to handle them. HTML Evaluation Engineering: Selecting a PC Plug-In DMM Feb 1, 2005 -- Most automated production test systems require a DMM and usually are integrated into a PCI, PXI, or VXI chassis. These architectures provide a favorable combination of speed, ease of integration, accuracy, reliability, reasonable cost, and small size. HTML BestTest: Choosing a Digital Multimeter June 1, 2004 -- Manufacturers typically highlight their highest accuracy and their highest speed. Unfortunately you don’t get both at the same time. Sometimes it is difficult to understand what accuracy goes with the speed you want. HTML
