PXI 6682 characterization

[dkennedy2010]

I am trying to characterize the time delay of the GPS signal on a PXI 6682.  I have been able to do this with a calibrated source, and my two GPS devices (I get about 100ns delay), and I need to do this for the PXI 6682.  I need to get the PXI 6682 to output a PPS signal that is synced to the GPS.  Currently I have is set to 1588, but I don't think that is right. 

I set up in MAX pfI2 to output a PPS signal, but what clock is it using to generate this?  I want it to use a GPS signal to accurately see the synce.  Thanks for the help, and I hope it wasn't too confusing.

Hi.

You can open a Test Panel for the PXI-6682 in MAX, in the 'Time Reference' tab (first one), click on 'Set Time Reference', and set it to GPS.  Wait for the 'Time Reference Present' LED to light up, indicating the board was successful in synchronizing to GPS.

Then you can go to the 'Generate Event' tab, select 'PPS' as the event type and you should get a PPS sync'd to GPS.
