Napatech SmartNICs can be configured to output a PPS pulse representing the phase (second tick) of the time stamp clock. The PPS output enables synchronization of third-party equipment to the SmartNIC time stamp clock. PPS provides reference for phase and frequency synchronization of the connected third-party equipment.
This ntservice.ini code line configures the NT SmartNIC for the setup in Illustration.
