Which combinations of parameter values on the USRP B210 software defined radio have least probability of crashing in use?
There isn’t a single “safe” set of parameters for the USRP B210 that guarantees no crashes (it depends a lot on your host PC, USB link, FPGA image, and what…
I am using USRP B210. I have set bandwidth to 56MHz. Maximum available sample rate is 10MHz. If i use that then computer crashes due to data overload after a few samples. I have had to reduce sample rate to 2MHz to avoid crashing.
Thanks — that context makes the problem clear. Below I’ll explain why your computer crashes, show the data-rate math with ASCII equations, and give straight, actionable fixes you can try…
