PPS signal measure, GPS GTPA013

by Gambox on Mon Mar 31, 2014 2:44 pm

Hi, I have some problem with the PPS signal of the GTPA013. I power on the device and I put in the PPS output Oscilloscope tip but I can see nothing. I expected to see a square wave o pulse witdh with 50ms of duration.

I believe the PPS must be enabled in software. It's not on by default.

Could you confirm that v3 Breakout with GTPA013 needs specific software command to enable PPS output!???

Upon further review, the decision in my previous post is reversed. Sorry about that...

The 1PPS is normally on. No command to enable it is required. In fact, there is no PPS-related command at all. You can't turn it off, either.
