Hi All,

This is my first post.

 

I have a Z3816A which is giving me an EFC error during start-up and a Alert
Led.

 

Before the error I get a EFC value of 484042 and the is 2.4 volts on the EFC
pin of the TCXO

 

Initially there are no errors.

 

After acquiring 4 satellites the error occurs, the EFC value is 0 and the is
about 20mV on the EFC pin of the TCXO.

 

Any suggestions?

 

I was next going to measure the output frequency on a GPS disciplined
counter.

 

Thank you
