  • Power sensor module for microwave test systems
    Patent number: 6397160
    Abstract: A module for use in automatic test equipment is disclosed. The module is especially useful for performing power measurements on high frequency devices. The module includes a power sensor and a plurality of EEPROM's that store reflection coefficient data for the power sensor. Computerized control circuitry in the automatic test equipment uses the stored data to reduce impedance mismatch uncertainties in the power measurements.
    Type: Grant
    Filed: June 4, 1999
    Date of Patent: May 28, 2002
    Assignee: Teradyne, Inc.
    Inventors: Thomas Michael Craig, Matthew Thomas Begg
  • Noise source module for microwave test systems
    Patent number: 6268735
    Abstract: A module for use in automatic test equipment is disclosed. The module is especially useful for measuring noise parameters of high frequency devices. The module includes a noise generator and a plurality of EEPROM's that store reflection coefficients and ENR data for the noise generator. Computerized control circuitry in the automatic test equipment uses the stored data to reduce impedance mismatch and Excess Noise Ratio (ENR) data uncertainties in the measured noise parameters.

  • Automated microwave test system with improved accuracy
    Patent number: 6249128
    Abstract: An automatic test system for microwave components. The test system includes internally switchable calibration references. As part of a calibration routine, incident power from a source is measured. During the measurement, calibration references are switched to change the amount of power reflected back to the source. Changes in the incident power are measured continuously while this change occurs. The resulting measurements allow the source match term to be determined. Correction is made to the source amplitude to adjust for the source match.
