Transmit Chirp Signal with AD-FMCOMMS5 and ZC702

Hi,

I am attempting to transmit a chirp signal via Simulink. I am using the AD-FMCOMMS5 with the ZC702. I can run the FMCOMMS5 sine wave transmit example with no issues. When I attempt to put my chirp signal into the Data in pins, I get an error saying :

"Unable to perform assignment because the left and right sides have a different number of elements"

I am not sure why this is the case. I know you can upload a chirp signal with IIOscope, and I would like to do something similar here and record data. For the IIOscope the problem is that saving data is only for one frame and I want a continuous stream. Any suggestions would be welcomed. My guess is that the chirp block in Simulink is not discrete, but I am not sure. I am able of transmitting other basic signals.

Thanks

    If you follow the error it occurs when filling the buffer. From the error itself one of the vectors must be a different size, the buffer for hardware or the input data vector passed to the Simulink block. Does your buffer size setting equal your input vector size?
