Re: [USRP-users] How to set channel B reception with rfnoc USRP E310?

As far as I understand the examples and RFNoC are sharpened for the N series of boards

As I understand it, you mean the Radio select parameter in the RFNoC Radio block. When setting the parameter to "B", an error is issued: Traceback (most recent call last):   File "rfnoc_fosphor_network_usrp.py", line 259, in <module>     main ()   File "rfnoc_fosphor_network_usrp.py", line 248, in main     tb = top_block_cls (fft_size = options.fft_size, freq = options.freq, gain = options.gain, host_ip_addr = options.host_ip_addr, param = options.param, samp_rate = options.samp_rate, tdecay = options.tdecay, trise = options. trise)   File "rfnoc_fosphor_network_usrp.py", line 71, in __init__     eleven   File "/usr/lib/python2.7/site-packages/ettus/ettus_swig.py", line 2431, in make     return _ettus_swig.rfnoc_radio_make (dev, tx_stream_args, rx_stream_args, radio_select, device_select) RuntimeError: Cannot find a block for ID: Radio_1

It does; the channel parameter on E310 is used to address the A- or B-side.

Does the 2nd argument to set_rx_antenna() indicate which radio port?  If so, try setting it to 1.

Hello, I'm trying to switch between all four USRP E310 inputs. For this, I use the command self.uhd_rfnoc_streamer_radio_0.set_rx_antenna ("TX / RX", 0) but I can only switch in channel A. RFNoC Radio does not have the set_rx_subdev_spec command. Tell me how can I switch across all 4 channels?
