Hi Does anyone have an idea as to what the maximum value of a sample when read in matlab is? I've got a BasicRx board and I'm injecting a 10dBm signal into RX-A. Using max(abs(sig)) in matlab results in 8.6458e+03. Is this what I should get, or should the maximum reading be higher?
USRP values are signed 16 bit values, so +/- 32768 range.
Also, can someone quickly tell me about the two inputs on the BasicRx board. Are they two different channels for sampling two different signals? If so, how do I get access to both in a Gnuradio app?
They are 2 different antennas for 2 different signals. Or both antennas can be used in combination for a complex IQ signal.
For usrp_fft.py (side A): -R A:0 uses the first antenna -R A:1 uses the second -R A:2 uses both antennas (IQ) -Josh
Thank you in advance. Sebastiaan
