W-2220B Temperature Test System
With 250B-2 or 250C-2 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 is published in a Microsoft Access data base 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
