W-2200B Temperature Test System

With 250B-1 or 250C Network Analyzer

  • Automated software based quartz crystal temperature
    test system
  • Measures over 75 different parameters
  • Parameter and curve fit characteristics are
    checked against easy to define QC limits
  • Crystals of different frequencies can be
    tested in a single temperature run
  • All data published in a Microsoft Access™
    database and can be exported to Microsoft Excel™
    for custom data analysis
  • Crystal part number can be used to set
    complete measurement parameters, QC limits,
    temperature test points, and data printouts
  • Printouts are generated using Crystal Reports®
  • Accommodates two dual row test wheels
    with extended life test head contacts
  • Easily loaded S&A proprietary sockets accept
    HC-45, HC-49, HC-43, HC-49US, HC-18, SMD and tubular
    type packages
  • Typically holds 508 devices per run
