Generate chirp signal in USRP RIO

[radityaangga]

hello,

 I have a problem, i can't generate chirp signal by using Labview Comm 1.1 through an USRP 2943R (RIO). there is an error on niUSRP Tx Write Data, that says, "the number of channels in the session does not correspond to the dimensionality of the data buffer.  Use the 2D Fetch or Write VIs when using multi-device sessions".  i've already tried to use the 2D Write but the result was just the same.

what should i do to solve this problem ?

Thanks

Hello radityaangga,

Are you trying to output the Chirp on both channels?

There is a coercion dot on the Write function. Can you please investigate that?

My theory is that you are writing a 1xsamples array to the Write function, which is expecting a 2xsamples array.

Regards,
