Note: The NTP100-OSC should periodically be set manually to the time of an accurate external reference such as another
NTP Server. See the Set Time/Date section that follows for suggestions .
The maximum “Validity” duration is adjustable in 1-hour increments. To always allow time dissemination and always
consider the internal clock source “valid”, set the validity duration to a value of zero “0”
[Hint: It is suggested to configure the unit to allow time dissemination and to enter a value of 0 in the “Validity duration”
field when using the NTP100-GPS-HS High Stability model.]
Deselect the “Allow time dissemination..” if you do not want the NTP100-GPS or NTP100-TC to serve time using the
internal RTC and TXCO oscillator while the unit is free-wheeling.
You may deselect the “ Allow time dissemination” if you do not want the NTP100-GPS-HS to serve time using the internal
RTC and OCXO high stability oscillator while the unit is free-wheeling.
