Hi all, I try to transmit a signal through an RFNoC Radio TX block in a USRP E320. I am using UHD 4.0 and GNURadio 3.8. My flowgraph in Gnuradio is something like this:
Host block => RFNoC tx Streamer => RFNoC custom block => RFNoC DUC => RFNoC tx radio When I test this graph with "number of ports" = 1 both in DUC and Radio, the flowgraph works properly and I can transmit data through the radio (red light on channel 0 is lighted), but when I set the number of ports to 2 both in DUC and Radio TX, no data come out to any of the TX/RX radio channels (leds are off). GNURadio doesn't report any errors. The radio block does not have a parameter to select a channel, I have assumed that in0 corresponds to RF A Rx/Tx channel (E320 front panel) and in1 to RF B: RX/TX. Do I have to specified channels somehow? Am I missing something? Kind Regards, Maria.
