 2250 Temperature Test System

 

FEATURES 

 

  • Automated, software based quartz crystal temperature test system

  •  
  • Measures crystal parameters over easily defined temperature profile
  • 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
  • Measurement data available in spread sheet, ASCII and binary formats
  • Crystal part number defines complete measurement parameters, QC limits, temperature test points and data printouts

[2250]

 

[Wheel]
  • Standard dual row test wheel with extended life test head contacts holds 254 devices
  • Easily loaded S&A proprietary sockets accepts HC45, HC49, HC43, HC49US, HC18, SMD and tubular type packages
  • IEC-444 Pi Network test head with extended life contacts and switch selected variable capacitor for load frequency measurements
