• 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

4.QIE10 Serial Register Programing4.1 Datasheet Information

Characteristics for configuration:• For correct operation with DC Current source we need to tune some internal parameters.• QIE10 Configuration: 64 bits Shift register• Done remotelly from Back-End.• Dedicated E-Ports for Control lines and LVDS level translators used.

4.QIE10 Serial Register Programming4.3 How it is done

• We have complete control over the different possible configurations via Console Application.

• Configuration Register 64 bits collected and sent trough UART to Back-End system.

• SRCK, SRIN and SRLOAD signals sent trough GBT Link.• Dedicated E-Link on Front-End connected to Level translators and QIE10

control lines.• Outcome Complete configuration performed remotely from surface.
