Hello all,

I am running some simple tests with some E310/E312 radios and would like to set one up to receive on two channels simultaneously.  How would I go about doing this using the UHD:USRP Source block?  I have no problem receiving on a single channel, but when I try to set up the block to have two channels, I get a, "Runtime Error: port number 1 exceeds max of 0." 

I am rather new to the E310/E312, and I'm testing them out over networked mode rather than embedded.  I have the device set up with a static IP address, which is configured in the Device Address box.  What would be the basic parameters needed to set up an E310 to receive on two channels?  I know the two RX channels would share the same LO, so I have the  center frequency set to the same value for Ch0 and Ch1.  I'm using GRC 3.8 and UHD 4.1.0.

I appreciate any help with this.  Thanks!

    Make sure your SUBDEV spec is:
    
    A:A A:B
    
    or
    
    A:0 A:1
    
    Depending on which version of UHD you're running on your E310.
