Offices of Measure mostly use NTP servers in configuration where frequency is locked on 1PPS available from 5071A atomic cesium clock.
However, above configuration cannot use UTC Timestamping from 5071A atomic cesium clock.
This is because 5071A includes cesium beam continuously traced by PC.
This connection occupies the only one rs232 interface available at 5071A.
Therefore, the NTP server uses simultaneously combination of 1PPS and Timestamps
where UTC Timestamps are driven from GPS satellites, and …
1PPS frequency reference is provided by 5071A cesium clock
Elproma has developed new NTP driver to support 5071A timestamps
Therefore, today Elproma offers new solution, …
where 5071A is the only primary time & frequency standard providing both 1PPS and UTC Timestamps directly to NTP server
This configuration does not need GPS anymore
NTP server uses simultaneously combination of 1PPS and Timestamps from 5071A
where UTC Timestamps are delivered via RS232, and …
1PPS frequency reference is still provided by 5071A as before
You can still trace cesium on PC. This information now goes through Elproma NTP server, which behaves transparent for PC requests.
