Hardware Roadmap[edit]

Design Objective
#1 Time Card based PPS measurement Scaleable use of the Time Card in a generic server to perform up to 4 PPS measurements

Software[edit]

Design Objective
#1 Time Card based PPS measurement Interface with Time Card driver and export PPS measurement data in a useful format

Potential Future Hardware Solutions[edit]

Core Hardware Objective
#1 TDC Small, cheap, and low power use-case
#2 PTM controller A PCIe based daughter card that can be synchronized with a high stability source (Time Card) over PCIe to scale PPS measurements
#3 UWB A method for distributing GPS and time to areas where measurements are made, but GPS is not available
#4 DPLL A discrete design based around a DPLL , removing the need for an FPGA
