Vertex Antenna Metrology Calibration Constants and NPAE Values


TIP Last Update: JeffMangum - 10 September 2009


Following table lists the metrology system calibration coefficients:
  • Tiltmeter zero points:
    • AN0
    • AW0
    • TiltXOffset
    • TiltYOffset
    • Tiltmeter Filter Time
    • Tiltmeter Blanking Time
  • Linear sensor correction curve coefficients:
    • SA2
    • SA3
    • phi2
    • phi3
    • Linear sensor Offset 1A
    • Linear sensor Offset 1B
    • Linear sensor Offset 2A
    • Linear sensor Offset 2B
...and the absolute value of the mechanically-measured non-perpendicularity (NPAE).
