  1. Mass termination board (MTBv2.0) full power test • Outline: • Test setup • Power consumption • Single ladder vs. full power test • Summary

  2. Test setup (1) • Production ladder power consumption: • ~2 A => ~1.3 A VDA + ~0.7 A VDD • Ladder emulation: • V_analog 3.3V @ 2.2  + 0.2  • V_digital 3.3V @ 4.7  VDA 0.2  sense 2.2  GND

  3. Test setup (2) RDO (Xilinx) MTBv2.0 1 PXL production ladder + 3 “ladders” (resistors)

  4. Single ladder vs. full power test - noise

  5. Single ladder vs. full power test - FPN

  6. Single ladder vs. full power test - offset

  7. Summary • No discernible difference between single ladder tests and full current load tests (@ 8A) • Ladder performance tested using our new MTBv2.0 board is stable under low and high current load conditions • This performance will be validated with a full sector test
