  2200 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
[2200]

 

[Wheel]
  • Standard dual row test wheel with extended life test  head contacts holds 254 devices

  •  
  • Easily loaded S&A proprietary sockets accept HC45, HC49, HC43, HC49US, HC18 and tubular type packages

  •  
  • IEC-444 Pi Network test head with extended life contacts and switch selected variable capacitor for load frequency measurements
