[time-nuts] Spectracom 9383 w/OXCO

Hi,

 

Last year I acquired one of these from ebay – and it seems to be working fine.

 

Having found this list while searching for something other – I thought this might be the place to ask 😉

 

The oscillator log on the Spectracom shows this (and always have while in my possesion):

I don’t like the FREQ ERROR part – but seeing FREQ ERROR= 0.00E+00 FREQ CNT= 1,000,000,000 makes me believe it’s just rather informational?

Or is this a case for concern?
