My New N210 always show "1074118626 local oscillator did not lock within the alloted time"

Hi,

About error "1074118626 local oscillator did not lock within the alloted time" I found the alike thread in here, but at my case that error only occures when I used two N210-newly purchase.

When I put them two on transmitter side, that error occures at write-VI (niUSRP Write Tx Data (2D CDB).vi<ERR>The local oscillator did not lock within the alloted time)

When I make them as receiver, that erroor come up again a block initiate-VI (nuISRP Initiate.vi)<ERR>The local oscillator did not lock within the alloted time)

I replace those two with the old N210 and that error, disappear. Why ?

Thank you~

Hi atafa,

It could be that the old and new N210s do not have the same firmware. You could try updating the firmware on your new boards and see if this fixes the behaviour:

Hi Libby,

About the firmware and FPGA, I always make sure that both of them are update. Thank you for your suggestion.

Finally, I found the answer of "why that problem (1074118626 local oscillator did not lock within the alloted time) occured" It was because unsynchronous LO between the two USRP. I had solved the problem after connected both USRP using MIMO cable without any change in the LabVIEW code.

I don't know yet why the old USRP didn't need that synch thing.. anyway.. I'm glad that my problem was solved.
