Part Number: TSW14J56EVM
Hi I am using the tsw14j56EVM along with the tsw38j84EVM. I am trying to use my own data within csv files and send them to the pattern generator. I have a matlab script which populates the csv file, I also loaded this file onto the High Speed Data Converter Pro GUI. My question is does the Data rate setting on the GUI need to match with the frequency of the signal? It seems to like this way with the test files which are provided with the software. I followed the test setup procedure described in the tsw38j84 manual but it seems to not be sent correctly. NOTE: I followed used a provided test file with and got the expected result. The only issue I can see with my data is the data rate. I am not sure How I can get it to match with what is required? I will include the code I have along with pictures from the GUI, Thanks for any help.
