2 limesdr behave differently. Is one faulty?

[ChrisLM]

This is a follow-up of LimeSDR PCIe bandwidth and GQRX - #23 by ChrisLM, since I was hijacking another thread…

For memo:

@ChrisLM

I’ve received my two limesdr (USB versions) and, very weird, with the very same conditions (same custom app using soapy listening at 60MS/s on dual channel, same antenna, same cables, same firmware version on the limesdr), one of my two limes systematically show me the “WARNING: phase search FAIL” message and then packets’ timestamps show discrepancy indicating that I am loosing packets. With the same conditions, the other card never shows the issue and runs fine.

@Zack, @andrewback, I raised the issue a month ago but, without any new for 14 days now, I begin to worry a little…
=> Is the limesdr faulty (despite it’s new)?
=> If so, does Crowdsupply or LimeMicro replace it? What is the procedure?
Thanks

[andrewback]

Crowd Supply will arrange to swap out if we can ascertain that it is indeed faulty.

@Zack, any suggestions before we arrange an RMA?
