HCAL Development Requirements • Expect to setup a uTCA at Fermilab which will handle both data and control functions • It will serve as a working testbench for FE Modules and the readout system – Characterize our analog ASICs ‐ QIE10s (Charge Integration Encoder) • DC charge calibration ‐ > slope, offset – Read/Write to local registers – Exercise L1 and L2 buffers – Exercise optical links
