MATLAB DAQ2 example is very slow and does not output from spectrum analyzer

Hi,

I am trying to run my custom device (An AD9234 ADC with zynq FPGA) together with matlab in order to grab the data and perform further processing with it.

Based on the daq2 example I managed to run the application, I changed the cfg-file in order to connect the correct adc. I got connection and was able to get data from the scope which looked like:

The signal from the osc, which is the correct one looks like this

What data is matlab displaying?

- The Spectrum Analyzer did not work. It gave me the following output : "Spectrum cannot be displayed for continuous or infinite sample times" but I did not find where to make the correct changes. I changed the scope from frame based to sample based but what to do with the spectrum analyzer?

- The overall system is pretty slow. I was only able to get data when I set the output data channel size to 100 samples. The daq2 example set the channel size to ~8192*128. Why is my system so slow? When running the osc it is pretty fast so the data might come fast enough but matlab runs pretty slow. I run this inside a VM but with 6-cores/8G Ram so this should be fast enough.

Thanks for any help,

Nils
