  • Patent number: 5396444
    Abstract: A data processing system for use in a measuring instrument having a keyboard with a plurality of numeric keys for entering numeric values and a plurality of terminator keys for indicating the completion of the entering of numeric values. Each of the terminator keys has associated therewith a pair of reciprocal exponents to indicate the weight to be applied to the numeric value. A processor is coupled to the terminator keys for automatically selecting one of the reciprocal exponents. That selection is deduced by the processor from the nature of the calculation.

  • Patent number: 5050107
    Abstract: A data processing system for processing measurement instrument data is disclosed having a processor for digitally manipulating the measurement instrument data, a memory for storing the digitally manipulated data, and a display. In one preferred embodiment, the display simultaneously displays side by side two traces of the data, so as to provide two independent side by side displays. The displays can be either real time or can be recovered from memory, and a plotter can be used to produce hard copy. In another embodiment, the display provides a trace of the data with a plurality of markers. The user can then choose one of the markers as a reference and the processor will automatically provide the value of the trace at each of the other markers relative to the value of the reference marker. In another embodiment, the system includes a keyboard having a value key for entering into the processor the current value of a marker on the data trace.

  • Patent number: 4816767
    Abstract: An RF network analyzer is disclosed which is suitable for both laboratory and automated production measurements. An important feature of the invention is the ability of the user to completely specify the method of calibration to be used. In particular the user can select any three arbitrary RF standards having known electromagnetic response characteristics and can attach them in any arbitrary order to perform the calibration of the instrument. This calibration is carried out by measuring the RF scattering parameters S.sub.11, S.sub.21, S.sub.12, and S.sub.22, storing the data in a memory, and then calculating vector error correction coefficients that are characteristic of systematic errors introduced by the RF network analyzer into measured scattering parameters.

  • Patent number: 4661767
    Abstract: A precision vector network analyzer which is suitable for a wide range of applications including both laboratory and automated production measurements and testing is disclosed. New measurement capabilities, greater ease of use, and nearly complete automation are provided. Contributions include fully coordinated communications between subsystem modules; real time, two channel, precision vector measurements with complete, internal error correction; wide frequency capability from RF to millimeter bands; combined time and frequency domain analysis and display; measurements either in the swept or step frequency modes; and user definable test functions and calibration device sets.
