Converting csv files to signals

[ishironagasaki]

I need to convert this csv file to an analog signal.  The timing and magnitude need to be exact

Sorry my internet browser was messed up here is the file

So, what have you tried? You are showing an image of an Excel file so save it off as a text file and read it with the Read From Spreadsheet File.

I've tried alot of the signal generation options, and the simulate arbitrary signal vi, but that requires that you enter in all 100000 points.

That has nothing to do with your question about reading from a file and if you are talking about the express function, your statement is not even true.

Well I know you can load .lvm files, but how do I convert the .csv to a signal?

[Dennis_Knutson]

I already told you how to read the file. The essentials of a signal/waveform consists of a y array and dt value. You showed both of those in the Excel file you had. You will get a 2D array from the read so just use the Index Array functions.

As Dennis already stated, use the Read From Spreadsheet File VI.

Yeah, I know I have to use the read spreadsheet vi, but after I read the spread sheet I have to convert the array to a signal.  I'm having trouble on finding the right signal generation vi.

Have you tried the build waveform?
