DPO72304DX Not Saving Y Data

As the title suggests my scope is not saving the y values of my waveforms. In the .csv output files each Y value is replaced by "#N/A". I've had this scope dump my data before when I ask too much of it processors. The weird thing is the data is still displayed on the screen. Not only that but maths can be performed on the time-domain data including FT to frequency domain. So the data is stored somewhere, it's not writing in to the files though.

I am using FastFrame set up. In the image the top window is a previously saved file while the bottom is the current problem. No changes were made to the setup between the two. The only difference is about two weeks had passed where it was unused. I guess my ultimate question is what the third number in each line of the output files represents and why is it missing from my files?

Hi Billy,

1) That third number represents your y value.

2) I am not sure why it's missing from one of your files, would you be able to share a picture of TekScope when you try to save a waveform which leads to this issue?
