[USRP-users] interpretation of received signal

Hi Marcus, I have no idea why you said that but I certainly did not mean to directly take the values that Marcus L mentioned and straight away add it in my report!. Since I am just learning about SDR, I just wanted an idea of what could be the minimum power levels that an SDR receiver can fairly c

Re: [USRP-users] interpretation of received signal

Thanks for a very good explanation on power levels Marcus. Actually I think I got the answer to what I was looking for. The "faintest reasonable signal level" that a typical SDR can process! (Typically around -120 to -130 dBm).! In my application, I have a bunch of channels through which I can

[USRP-users] interpretation of received signal

Hi Konstantin and Mike, In fact I started with 0 gains for both transmitter and receiver with different amplitudes of input signal. The received power is always in the range of -80 dbm to -100 dbm. I am not sure how to say that a certain received power (in dbm) 'is acceptable' when given an input

[USRP-users] interpretation of received signal

Hi all, I am trying to transmit and receive a simple 10 kHz tone using a single USRP B205mini-i. The input power is 0 dbm ( The amplitude of 10kHz tone being 45mV). The transmitting and receiver antenna are same omnidirectional type each having 3 dbi gain. I set the transmitter gain as 8 and recei

[USRP-users] max input power

Hi Marcus, I think I did'nt frame the question properly!. I know the calculations but I just wanted to know in what voltage range must the input be given to B200? (in mV-micro volts range?) regards Nirmala ___ USRP-users mailing list USRP-users@lists.e

[USRP-users] max input power B200

Hi, B200 mini data sheet mentions maximum input power as 0 dBm. A 1V, 1 kHz signal will give 0.5W power which is above 20 dBm and way above 0 dBm! Can this please be clarified? regards Nirmala ___ USRP-users mailing list USRP-users@lists.ettus.com htt

[USRP-users] transmit and receive - B205mini-i

Hi, I have just started programming simple scripts in matlab for B205mini-i. Can I transmit and receive simultaneously using SDRUtransmitter and receiver objects in Matlab? I also tried to use simulink, and gave a simple cos signal as input, the value is 1 X 151 vector, just cos values between

[USRP-users] USB connector on B205mini-i

Hi, Has anyone tried to use Matlab with B205mini-i on windows? Apparently Matlab does'nt recognise the board when plugged to USB 3.0 port. It however works when used with USB 2.0 ports. Ettus recommends to use USB 3.0 specially on B205mini i. Request for help regards Nirmala ___
