Status 

Provides current status on the NTP100’s operation, including current UTC time/date on the unit, as well as other 
operational information relative to the available device models. 
 
Requests serviced – Number of NTP requests serviced since the unit was last powered on. 
 
Reference – Current time reference.   
 
NTP100-GPS: GPS when locked to GPS satellites, otherwise Internal Real-Time Clock. 

NTP100-TC: Time Code format when locked to external time code input, otherwise Internal Real-Time Clock. 

NTP100-OSC: Internal Real-Time Clock 
 
Last reference loss – Last time/date upon which GPS satellite signal was lost, or n/a if the event has not occurred since 
the last power on. 
 
Last reference regain - Last time/date upon which GPS satellite or time code signal was re-acquired from a loss state.

 

 
NTP Status /Stratum Level  - NTP stratum level for present reference as defined  in the device configuration settings.  
 
The remaining information in this status display is for technical support purposes only and is not useful for the end-user.
