Re: [USRP-users] TX underflows when using multi_usrp vs. two independent tx_streamers

Forgot to mention For the reason I mentioned above, I typically put a time stamp on every packet I send (rather than just the first packet) so that if errors occur, subsequent packets will still be aligned. Rob On Mon, May 11, 2020 at 4:23 PM Rob Kossler wrote: > Great. One caution though.

Great. One caution though. When you do have errors, I think that if multiple channels are in a single streamer, UHD keeps them time aligned after the errors (not 100% sure though). If you have separate streamers, then if one of them has an error but the other does not, the outputs may no longer

Hi Rob Just want to let you know that using one tx_streamer per USRP works like a charm. So far I've streamed continuously at 184.32 MHz for a few hours without any underflow. I didn't test it as intensively with 200MHz, but so far it works as well. So thank you for pointing me in the right dire

If I understand you correctly, then I need to create another block uhd self.uhd_usrp_source = uhd.usrp_source ( ",". join (("", "")), uhd.stream_args ( cpu_format = "fc32", channels = range (1), ), ) so I created it. But I don’t understand how it work

Hello, I'm using the USRP X310 with CBX-120. I set the radio sample rate to 184.32 MHz but I have the following message: [WARNING] [X300 RADIO] Requesting invalid sampling rate from device: 184.32 MHz. Actual rate is: 200 MHz. Isn't it possible to set it to that sample rate? Thank you.
