Hi, I am testing frequency hopping in a loopback mode on B210 using external RF loopback cable. For First slot Tx/Rx is done at freq 562 Mhz. Subsequent slot is at 582 Mhz. I have observed Rx packet loss when Tx is done for entire slot duration. Please let me know if this is expected or if some c

[USRP-users] Concurrent Rx on USRP E312

2018-02-28 Thread kailash kumar via USRP-users
Hi, I am trying to explore the possibility of using Rx channels(0,1) independently and concurrently on Ettus USRP E312. Here is what I am trying: USRP 1 --> Rx Freq 1 --> Filter --> Demodulation and Decode 1 --> Audio Sink --> Rx Freq 2 --> Filter --> Demodulation and Decode 2 -->
