Thanks, Dan. I've seen the *.tsw test files available (and have sent them to my DACs), my question was more to what those numbers represent for complex data. Would it be "Real, Imag" four times for the four channels, for a total of 8 columns? I've successfully sent frequencies from the HSDC GUI to each of the 8 channels and verified the frequency with an analyzer. I BELIEVE I've sent one of the *.tsw test files, as well... and a *.csv, as well. I'm using an LMFS setting of 4421, which actually brings me to another question... how to communicate with all 8 channels using one INI file? Thus far, I've used an INI file for lane 0-3 and a second file for lane 4-7 using the following lines in the ini: "Lane Mapping=lane0:0,lane1:1,lane2:2,lane3:3" or "Lane Mapping=lane0:4,lane1:5,lane2:6,lane3:7" What variables would I need to change in the INI to address all 8 lanes? Thanks for the ref design. We'll be linking 6 of these modules together and time alignment is one of the issues on the table. It'll help a ton.
