When GPS started broadcasting the leap second notification on July 19, 2016 for activation on Dec 31, some GPS timing receivers erroneously inserted the leap second resulting in a 1 second time error.
The TSync-PCIe can be set to generate interrupts at a desired rate by using the General Purpose Output (GO)
This article applies to fielded bus-level timing boards that requires a replacement of the external GPS/GNSS antenna-receiver combination.
Except during power-up, there are always 10 million cycles of 10MHz between each 1PPS output.
A certain type of message without a data payload after a long idle period such as a reboot (such as a power management enable signal) from a computer's PCI express controller to the Spectracom TSync-PCIe timing card can prevent the OS from booting up, or cause the card to 'disappear' from the OS
TSync-PCIe bus-level timing boards that are operated in mobile platforms (e.g., truck, airborne or marine platforms) and are synced to GPS, need their GPS receiver reconfigured for Mobile ("Continuous") mode.
