[time-nuts] Z3815 question

[Hui Zhang]

Sorry I forgot a qeustion about EFC, last night when I power on my Z3815A, it had a alarm message is "EFC limit", I use follow command to watch EFC value:


Sent: :DIAG:ROSC:EFC:ABS?
reply: +489118


Sent: :DIAG:ROSC:EFC:rel?
reply: -6.70809E+000


And then, I reboot the device, the alarm disappeared, the EFC value is:
Sent: :DIAG:ROSC:EFC:rel?
reply: +5.78499E-001


Sent: :DIAG:ROSC:EFC:ABS?
reply: +494788

So, I want know what is normal EFC range of Z3815A?
