11.4.4.Using NTP and GPS/NMEA for System Clock Synchronization
The system clock controls the date and time assigned to configuration and report files
and controls the auto-start / stop function. xGenius users can manually set the system
time and date by entering the correct values but they can also synchronize the clock
with an external NTP server or GNSS. The NTP server must be available through the
management Ethernet port. The GNSS timing is received through the 1 PPS / ToD
clock input or through the built in.GNSS module, if available (See section 2.6).
Table 11.9: Time Source Configuration Options
Setting Description
Date This is used to configure the current date. The date is used
for the Autostart/stop features and other purposes. The date
has to be entered with the following format: dd/MM/yyyy.
You can only modify the date if the current time source has
been set to Manual.
Time This is used to configure the current time. The time is used
for the Autostart/stop features and other purposes. The time
has to be entered with the following format: hh:mm:ss.
You can only modify the time if the current time source has
been set to Manual.
Time source It is either Manual, NTP or GPS / NMEA. The meaning of
each configuration option is as follows:
• Manual: The user configures the Date and Time fields
manually. System date and time is controlled by the inter-
nal clock.
• NTP: An external Network Time Protocol (NTP) server
controls the value of the Date and Time fields. The system
is synchronized with the server each time the equipment is
restarted or when a new capture is run.
• Time reference: The unit is configured to get the system
time and date from the GNSS satellite systems tor ToD.
This setting is available only if the unit has been properly
configured to receive a a time reference based on any of
these interfaces (See section 2.6).
UTC offset (hours) This is the time difference in hours between your local time
zone and the Universal Time Coordinated (UTC) time zone
This setting makes sense only if Time Source has been con-
figured to NTP or Time reference.
