▪ Details of the Dilatometer Control Module (DCM) Test
▪ Obstacles overcome
▪ Remaining tasks
▪ Lessons learned and knowledge gained
▪ Questions
3. First Steps
▪ Module information
▪ SROM and Firmware
▪ Monitor Voltages
▪ SIMM Card Test
▪ Benefit of Test Runner
▪ Stream line necessary tests for all modules
4. Testing the Transformer Taps
▪ Checking the Taps with standard Capacitors
▪ Verify the relationship between taps and ADC Counts
▪ Log-Linearity Fit yields slope of
▪ Checking the Taps with a specified Imbalance
▪ Utilizing the binary tap search
5. Calculating Differential Non Linearity
▪ Calculate for Tap Values vs. Voltage Imbalance
▪ Checks across all taps, -63 to 63
▪ Calculate for Coarse DAC Values vs. Voltage Imbalance
▪ Checks across every 512th DAC Value, from 0 to 65536
▪ Test Runner checks the minimum and maximum DNL value of each
▪ Plots DNL vs. Taps and DNL vs. DAC Values
