Issue Details

I have an Waveform Generator module that supports User-Defined Waveforms, but am getting an error like the one below after selecting my file. What needs to be modified in my existing file to get this to load properly?
 

Solution

Verify the following before attempting to load the file in:
  1. Make sure we are only loading in .csv files as they are the only supported file type for User-Defined Waveforms in InstrumentStudio.
  2. Ensure we have the exact amount of samples requested by the "Waveform points" specification found in the device's user-manual. In the example above, we see that exactly 8192 samples are required.
  3. Investigate how the .csv is formatted in a tool such as Microsoft Excel. InstrumentStudio is expecting to have the data be in the same row. It will not load in properly if the data is in a single column.
