[USRP-users] B210's FPGA programming dangers

2018-08-27 Thread Javier Coronel (Expo Impex, S.L.) via USRP-users
Hi all! I want yo do some experiments on the FPGA firmware. Is there any danger on this?. I mean, can I accidentally break the firmware loader? Thank you all. -- Un saludo, Javier Coronel Visite nuestra web: www.expoimpex.com

[USRP-users] Frequency tuning

2018-03-04 Thread Javier Coronel (Expo Impex, S.L.) via USRP-users
Hi Everybody!, I have a B210 and I have done a MIMO frequency scanner to send and receive. I always tune the same freq for both 2 Tx and 2 Rx. Everything works very well even working at a Sampling Freq = 30MHz. But I have checked that the functions set_tx_freq and set_rx_freq (that I call 2 tim

Hi Marcus, Sorry for the error in the plots (I forgot doing an axis square;). I am talking about why I get a normal I vsQ plot using a pure frequency and why I get a romboidal shape when I transmit a varying frequency. This phenomenon does not depend on the carrier frequency, the sampling rate o
