Hall D Collaboration, December 2003 --R.C. Cuevas F1TDC Test Details Two 1st Article Boards will be inspected and tested thoroughly After JLAB approval, remaining 48 boards will be assembled Test ‘station’ has been prepared. FPGA code will have to be loaded on each board. DAQ routines are established and will provide functional testing for each production board. Full crate testing and multi module [Block Read] testing will also be performed. F1 will require further testing before loading on-board EEPROM with final initialization data. 4/21/2019 Hall D Collaboration, December 2003 --R.C. Cuevas
