Thanks Nick for your answer.
Well, so I am working with OpenBTS and I understand that it sets parameters
such as the LNA gain at the Rx chain of the USRP B210. So in my research I
got to think that I should know How my RECEIVER works in terms of noise
floor it detects at a certaing LNA gain, so I c
Oscar, that document covers a *lot* of testing using quite a lot of
expensive calibrated instrumentation. Maybe you could elaborate a bit on
what exactly you want to test, and why?

Thanks Nick and Neel for the help.
So, do you have any suggestion how I can obtain the following curves:

with for example GNURadio flowgraph?
Thanks

Thanks Neel and Nick for your answers.
I took note of your suggestions and I am doing some tests to figure out the
idea a little more. So also I found the following pdf containing USRPB210
curves:

I have a question here, on the slides titl
Hello Oscar:
The maximum safe input power for the B200/B210 is 0 dBm. But that is not
the level that is full-scale on the ADC. You will need to determine
empirically what input power level results in a full-scale signal on the
ADC.

Neither. It will depend on the gain setting and individual variation in the
device. It is not calibrated to any specific dBm value and if you require
dBm you must calibrate your readings against a known source. The listed
maximum power figure is a maximum to avoid damage to the device.
