[USRP-users] Re: X310 Twinrx matlab issue

Yes – this is a bug in the MATLAB code – we obviously shouldn’t test and fail 
transmit on a receive only daughtercard…

You should be able to ignore this – and continue to use the Radio in MATLAB.

Ali,

your screenshots suggests that the Matlab Toolbox tries to verify the TX on the 
board but TwinRX has only 2RX. This is something Mathworks would have to fix.

If you suspect something is wrong with the TwinRX USRP you could also verify it 
using uhd_usrp_probe (to check whether the USRP is detected correct) and  
rx_samples_to_file (to verify you can receive data from it).

Subject: [USRP-users] X310 Twinrx matlab issue


Dear all,

I have been using X310 (two SBXs) to run a matlab example with no issues. 
Recently we bought another X310 (two Twinrxs) to run the same matlab code 
(using the same machine), however, I have been facing some issues. I had to 
update the firmware by using sdruload() on matlab however when I do the 
Hardware setup by using “Communications Toolbox Support Package for USRP Radio” 
the test fails (as shown in the attached screenshot).

When I run the matlab example, it shows me the error shown in the other 
attached screenshot.



Since I have no issues when using the old X310 with SBXs, is the issue because 
of Twinrx?



Any help would be much appreciated.

Kind regards,

Ali

Not too many MatLab folks on here, but it looks like you're trying to 
*transmit* with that MatLab code snippet.  The
  TwinRX cards DO NOT SUPPORT transmission.  They are two-channel, 
receive-only devices.
