Can I use Labview8.2 with GPIB interface to read from data file to control DC power supply Agilent 6674A output waveform?

[hiepn98]

I am currently working on the project to control Agilent 6674A (DC power supply up to 60V VDC output).  If I have the data file (Voltage vs Time), Can Labview using the GPIB interface to read from the data file , so the 6674A can output whatever the wave form from the data file ?

The output from Agilent 6674A will be capture by Data Acquisition Card or Scope .

Sure you can. What specifically do you need help with? You've got a driver available to control the instrument and you can easily read the file. You could use something like the Read From Spreadsheet File. You would have a 2D array with voltages in one column and the times in the other.

Thanks for your reply , I am very new to Labview . I need help to build the GPIB VI to read the data file . Am I correct ?

Depending on the format of the file, you have built-in functions to do the read. A text file with comma or tab separated data is the simplest. The function I named is designed for that. If you get stuck somehow with the read, post an example of the data file.

For learning LabVIEW, you have some tutorials to start with.
