W-250B/6SA Crystal Plating System Upgrade

  • Extends the frequency range of the SC-6SA Plating System1 to 200 MHz
  • Increases frequency accuracy
  • Precision plating to load resonant frequency using "Measured FL" method
  • No physical capacitor is required
  • Uses existing filaments and crystal wheels
  • Two Pass plating
  • Over 40 different crystal parameter measurements including DLD and Spurious
  • Measured parameters checked against user defined QC limits (No ring test required)
  • Supports wheels with different number of positions (e.g. 72 or 144)
  • Upgrade can be configured for a variety of plating system models
