  • Page 13: Chapter 2- Performance Verification

    Chapter 2 — Performance Verification Introduction to Performance Verification This chapter provides procedures to be used to verify the performance of ShockLine MS46131A. There are many levels to the concept of VNA “verification”. On the explicit VNA hardware level are operational checkout items such as port power and noise levels. On the calibrated instrument level (which includes the VNA and the calibration kit or AutoCal Automatic Calibrator) are the residual specifications (corrected directivity, source match, load match, and tracking) which are measured using traceable airlines (absolute impedance standards).

  • Page 14: Second Tier Of Uncertainty  Systematic Measurement Errors

    2-3 Electrostatic Discharge Prevention Performance Verification Second Tier of Uncertainty  Systematic Measurement Errors The second tier of uncertainty, corrected or residual uncertainty, is the result of the accuracy enhancement of VNA calibration to remove systematic errors. Systematic measurement errors are components of measurement error that in replicate measurements remains constant or values in a predictable manner.
