SRG-4500 User Guide (v7.0)

NTP Option • 131

Keep the following mind:
• The time-code needs to be checked and updated each time the NTP Server is detected. 
• However in marginal networks the “question-response” message times may be so variable the time-code update 

should be suppressed until it has been valid for a number of seconds.

• Once the time-code has been set by the NTP Client, the SRG-4500 should not need to re-check the NTP time 

unless a crash lock has been forced by the phase locking arrangement.

Simplified NTP Flowcharts

No frequency or phase can be accurately inferred from the NTP system.
