BE-BI-BL Jose Luis Sirvent Blasco 6 2. QIE10 Testing Preparations: 2.1 Trying to cover all the dynamic range (10000 samples = 250us) CH1  CH2 

BE-BI-BL Jose Luis Sirvent Blasco 7 2. QIE10 Testing Preparations: 2.2 Zoom to check logarithmic linearity (QIE10-CH1)

BE-BI-BL Jose Luis Sirvent Blasco 8 2. QIE10 Testing Preparations: 2.2 Zoom to check logarithmic linearity (QIE10-CH2)

BE-BI-BL Jose Luis Sirvent Blasco 9 2. QIE10 Testing Preparations: 2.3 New Set-Up for linearity Studies Back-End System Front-End System Sub-Femtoamp Current Source (Keithley 6430) 3 x LHC Clock TunnelSurface SMF 9/125um UART (COM) IEEE 488 (*GPIB-USB-HS) * GPIB : General-Purpose Instrumentation Bus

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? BE-BI-BL Jose Luis Sirvent Blasco 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

BE-BI-BL Jose Luis Sirvent Blasco QIE10 Testing Preparations: 2.5 Very preliminary data taken with the Set-Up (ADC_Counts) Region Studied: Range 0 (-16fC to 592fC) Current (640nA to 23uA) Each Current = 1000 points (25 us) Each Point = mean of 250 measurements Points identified by CID numbe r DRAFT !! Subrange 0 Subrange 1 Subrange 2 Subrange 3
