Push the high IQ sampling rate for multiple synchronised USRP 2943R with Network Ports configuration

HI Muffin,

 

Thanks for your reply. 

 

1. If I move the data fetch in the red circular, it will report the same error as I posted before. To be honest, I think the out loop data fetch will be matter.

2.  I tried the USRP_Rx_continous_8_channel.vi. For this VI, with clock and and PPS from octcolck. I can run this VI in 5M IQ sampling rate. 

 

3. I feel like with network port configurawtion and corresponsing driver, it may never achieve 8 synchronized channel on 40 MHz IQ sampling rate.

 

I notice that Labview seems like provided different blocks (or drover) for USRP and USRP RIO. WIthout accessing to the FPGA, high IQ rate cannot be achieved.

 

Cheers,

 

Bo

True_Boombo,

 

How are you connecting to the USRP RIO? Through Ethernet or through a PCIe connection? 

 

And what happens when you increase the IQ sampling rate on the example? Does it give you an error?

Hi Muffin,

 

I am connecting 4 USRP 2943Rs with 2 Network card, each card has 2 ports. 

 

If I increase the IQ sampling rate, it simple report overflow error (the solutions are: reduce sampling rate, increase number of samples per fectch.....). 

 

Cheers,

 

Bo
