This is an approximate. Actual value will depend on the SFPs used.
2
The use of packet slicing and hardware filtering is recommended for 10G capture to avoid oversubscribing the USB 3.0 interface (3.2 Gbps).
3
Due to the nature of SFP modules requiring power for operation, ProfiShark 10G/10G+ doesn't include a bypass feature for fail-safe monitoring.
An external TAP can be employed in order to implement fail-safe monitoring.

1.4. Advanced Timestamping

ProfiShark 1G+ and 10G+ offer multiple advanced timestamping features. The GPS chip can retrieve the
UTC time, and synchronize it with the internal PPS, with a typical precision of ±32 ns. ProfiShark 1G+ and
10G+ can also retrieve the time via SNTP (using ProfiShark Manager or CLI tool), or use the internal RTC
(real-time clock), and synchronize it via an external PPS signal. A PPS output is possible, for
synchronization with another ProfiShark device, or with any other device accepting a PPS input.
These features can be combined in different ways, providing multiple possible options for accurate and
precise timestamping of packets.
The settings and information related to advanced timestamping are located in the ProfiShark Manager's
Timing
Tab. This tab is only available when a ProfiShark 1G+ or 10G+ is connected.
Note: For the best results, the GPS antenna should be set up outside, or near a window. Other factors can
affect results, such as weather, cloudiness, and geographical location in regards to satellite availability. The
GPS can take a minute to synchronize the UTC time with the internal PPS. The stability of the
synchronization increases over time and may take up to 15 minutes to reach its peak.
