I’m currently evaluating the best USRP choice for testing a specific DUT which has a build in GPS receiver.
Our approach would simply be to have a recorded GPS using a USRP unit and play back the same signal.
check if our DUT can read out that playback signal.
I’m currently considering using a 292x model but have questions if the 2900 models would work for this application as well?
Or would you even consider to go with the 293x models? High position accuracy is not required we would just like to validate that the GPS in the DUT “works”.
I have 10Mhz reference clock generator in my setup.

Did you already choose an USRP?
We are currently thinking about the same and want to test it with a 2900.
Best regards

not sure about 2900. Currently I am using 2920 for my GPS module testing with wider test limits.

I tested it with the 2900 and it is possible to used for recording and playback of GPS signals without problems.
