Navigate to Capture > Interface Configuration > Advanced Timestamp to configure the GPS/PPS advanced timestamping settings.



Time Source
Select the source from which the time will be used for timestamping:

• System: Use the system time and ignore any PPS signal coming from the PPS port.
• System PPS: Use the system time and synchronize it with the PPS signal coming from the PPS port (if present).
• GPS: Use the time received from the GPS antenna connected to the GPS port (if present).

PPS Output
If checked, the PPS port will be set to output mode, sending out a PPS signal if the GPS is synchronized.

GPS Synchronized
Shows whether the GPS port is receiving time information from the GPS antenna.

GPS PPS Signal
Shows whether the GPS signal is stable enough for GPS PPS to be used.

External PPS Signal
Shows whether the PPS port is receiving a PPS signal.

Time deviation
Shows the deviation between the internal clock and the reference (external PPS, GPS PPS, or system PPS).

Set Time from GPS
Forces device to instantly synchronize its timestamp clock with the GPS source (if available).
