Re: [time-nuts] 10 MHz output level from DATUM 9390...

2012-12-17 Thread Robert Watzlavick
I believe you can adjust the level of the 10 MHz output.  The schematic 
shows a pot at R60 or R50 (the scan isn't clear) connected to U18 which 
drives the 10 MHz sine signal.

On the scope I see 950mv RMS with 50 ohm termination, 1.5V RMS with 1M. This is 
on a 9390-6000 OCXO with the default timing output configuration, 10MHz on J7. 
Hope this helps.

Gang,

Does anyone have a DATUM 9390 series GPS receiver that can tell me what the (50 
Ohm) terminated output level of the 10 MHz spigot is.  One of mine started 
spurring and the other one is clean, but seems way to high in output level.

Thanks,

[time-nuts] 10 MHz output level from DATUM 9390...

Gang,

Does anyone have a DATUM 9390 series GPS receiver that can tell me 
what the (50 Ohm) terminated output level of the 10 MHz spigot 
is.  One of mine started spurring and the other one is clean, but 
seems way to high in output level.
