    The artifact standard, an object which embodies the physical quantity to be standardized, has served the metrology community well. Its great merits are its stability and the precision with which it can be compared to other like artifacts. Its use as the basis of a measurement system is not without drawbacks however. Among these are: its definition may be arbitrary, it is maintained by a national o... View full abstract»

    An electronic system developed for area measurement is described. A standard X-Y recorder specially adopted with a light pen was made to scan the area under test and give a TTL logic signal that changes state whenever the area circumference is crossed. From such information the microcomputer is programmed to calculate the area using Simpson's rule and display the result on a seven-segment display.... View full abstract»

    Productivity is an issue of compelling importance in the application of measurement technology. Increasingly difficult requirements associated with the high-volume measurement of ever greater groups of physical variables have resulted in measurement systems whose complexity and costs usually exceed that of the system measured. This paper treats productivity as a systems issue and identifies and di... View full abstract»

    Until recently, receiver noise parameters (noise figure, effective input noise temperature, operating noise temperature) have been measured using classically analog instruments. Certain characteristics of these instruments require the user to do some "off-line" manipulation of the data in order to obtain an accurate, fully corrected result. These calculations involve. corrections for image respons... View full abstract»

    Software has been developed to record signals in automated data-acquisition systems that support pulsed power accelerators at Sandia. The software achieves flexibility by being entirely table driven. Before each accelerator shot the program processes input files and then sets up and checks out all programmable hardware. After the shot, the program automatically reads each signal, corrects it, and ... View full abstract»

    A pulse generator for testing the approximate step-response of waveform recorders is described. The initial and final levels of voltage steps are each programmable within the range of ±1 V for a 50-¿ termination and within ±5 V for a high-impedance load. Voltage steps within these ranges settle to within ±0.02 percent of full-scale range (FSR) in less than 30 and 40 ns, respectively, for a loa... View full abstract»

    A solid-state reference waveform filter has been developed which uses the Maxwell-Wagner capacitor effect. This filter is realized in a stripline configuration with a lossy dielectric consisting of a thick (5-¿m) layer of SiO2 on Si. The equivalent circuit of this filter is equivalent to that for previously developed filters which used a lossy liquid dielectric. A preliminary design has been comp... View full abstract»

    The complexity of integrated circuits has increased to the point that the integrated circuit's (IC) internal circuit components affect the ability of in-circuit testers to accurately measure analog components connected externally to the IC. For analog circuit analyzers, the ability to describe the IC's internal electrical equivalent using standard components, R, L, C, etc., improves the automatic ... View full abstract»

    Calibration appears to be an area in which automation can produce a significant improvement in productivity. However, the degree of success in automating the calibration function is highly dependent on the approach chosen. This approach must account for the workload characteristics commonly found in calibration operations, yet must be flexible enough to offer a solution for new and/or unique metho...
