USRP Fetch Rx giving error on higher IQ Rates

[umairpak1]

My USRP2920 gives error when i recieve and hear data at higher IQ rates.works perfectly fine in 200k IQ rate.I dont know whats the reason as USRP 2920 have BW of 20MHz.

The pics are attached showing error.

The block diagram is also attached.

 

Have a nice  and productive day!!!

It also seems to work at 1M, but not at 3M IQ rate!

Maybe that IQ rate setting is too high for the communication bus used by the USRP? Or the "number of samples" should be adapted to your sample rate, too?

Did you note this remark in the datasheet?
