Hardware Roadmap
| 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
| 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
| 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 |
