Thanks for you quick answer Marcus:

I always thought it was impossible to create 2 multi_usrp objects which connects to the same X300 device. Is this really possible?
I can try that on my side later if you think its possible.


Best regards,
Serge
I would say try it. But now that you mention it, it may not work. I'm not at my lab right now, or I'd try it myself....

    Hi all,

    I'm trying to use 2 different sampling rates the 2 TX channels of
    a X300.
    Basically, I create 2 different tx_streamers, and call
    usrp->set_tx_rate() for each channel.

    I'm getting this error from UHD:
    Multiple sampling rates downstream of TX Terminator 0:
    RuntimeError: Node 0/DUC_0 specifies 1.25e+07, node 0/DUC_1
    specifies 2.5e+07.


    I'm using UHD 3.10.3.0.
    Can you tell me if this is expected, or should I be able to use 2
    different sampling rates?

    Thanks,
    Serge
    If you want different sample rates, you'll likely need to create
    two independent multi_usrp objects to contain the streamers.
