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, Burt, K6OQK Burt I.

Burt - 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.

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. -Bob On 12/15/2012 05:37 PM, Ziggy wrote: > Burt - > > On the scope I see 950mv RMS with 50 ohm termination, 1.5V RMS with 1M.
