• Performing Linear – Logarithmic Current Sweeps:• Unified Set-Up for ICECAL & QIE10
• GPIB interface allows control of other instrumentation (Function Generator):• Compatibility with future tests (TDC, Synchronous pulses response)
• Testing Control managed by “Console application”:• Set-up instrumentation configuration• Optical Link supervisor with feedback for user (me)• Back-End management (Trigger readings and collects data from LPDDR memory)
• Test Procedure (Console App):• 1. Set-Up Link• 2. Set-up Instrumentation• 3. Current Selection• 4. Trigger Storage on Back-End (1000 points)• 5. Read Data from LPDDR PC• 6. Store measurement on New CSV file• Final Sweep Value?
2. QIE10 Testing Preparations:2.4 What is it for?
• Test Procedure (Matlab Script):• 1. Open CSV file• 2. Calculate ADC mean & std. deviation• 3. Store values• 4. All files processed?• 5. Calculate QIE10 nominal ADC• 6. Plot measured Data • 7. Plot QIE10 nominal ADC values
