[USRP-users] "No upstream blocks" Warning

2018-09-07 Thread Sebastian Bräuer via USRP-users
Hi, I am currently working on a custom rfnoc block that needs input from the DDC but also gets samples from the host and sends them to the radio via the DUC. The block works perfectly in simulation and even in gnuradio but for some reason I cant get it to work in pure UHD.  In my UHD code I always

The issue is on your output side. It has been explained to me (I think it is somewhere on this mailing list due to an issue I and other have had), that you can't mix ports to be both host and rfnoc streams on the same side of the RFNoC block. So it sounds like the input side has both inputs co

Okay, thanks for the advice. I added a FIFO in between the host and my block. I had not thought of this, because I never really intended to receive samples from this port. I just need a port to get the receive chain started. Now I'm not a getting a warning anymore, which is good I guess. But stil

[USRP-users] X300: Can we use different TX sampling rates on RF A and RF B?

Hi all, I'm trying to use 2 different sampling rates the 2 TX channels of a X300. Basically, I create 2 different tx_streamers, and call usrp->set_tx_rate() for each channel. I'm getting this error from UHD: Multiple sampling rates downstream of TX Terminator 0: RuntimeError: Node 0/DUC_0 specifi

Thanks for you quick answer Marcus: I always thought it was impossible to create 2 multi_usrp objects which connects to the same X300 device. Is this really possible? I can try that on my side later if you think its possible. Best regards, Serge - - - - - - - - - - - - - - - - - - - - - - - -
