Testing Components• Proposed ORNL

Custom Pulse Board– This board can have

programmable input patterns

– Also can have programmable input capacitance

– Programming will be done with USB to shift-register interface

Under construction

TPC Rev. 0 FEC

• Status: 6 PCBs fabricated/ 3 populated– Arrived at ORNL: 9/12/2016

• Preliminary testing:– No shorts on power input– Ground measurements as expected– Most configurations switches set as desired

– Working on GBT appropriate configuration

• Summary§ FEC boards received at ORNL and preliminary testing started§ Parts for FEC Test Bench are at ORNL§ Custom cabling between FEC and Lund pulse distribution boards

being prepared§ Planning for future custom pulse distribution board§ C-RORC control/drivers working§ Proceeding with C-RORC to VLDB GBT communication tests this

week§ Then, fuse program FEC GBTx registers and start C-RORC to FEC

communication tests.
