Displaying waveform from oscilloscope

Hi, I have huge issues with displaying live waveform from my oscilloscope,, Tektronix TDS520

 

I browsed through similar questions on these forums and tried to read vi's authors uploaded but most of them contains sub vi's which are not provided, making examples more or less useless as I don't know what is happening in these sub vi's..

I checked NI driver for this oscilloscope, I can't find my way around it, to complicated, many other functions, can't see any oscilloscope commands I read in specification, there are sub vi's missing and as a whole it doesn't provide me much help.

 

As you already are aware my experience with LabView is very limited, to add I have only 2hrs per week when I can actually work with the machine, which makes this task very hard for me. I can't use NL or other provided drivers, has to be done by myself.

 

What I'm looking for is, more or less, a step-by-step tutorial, how to work with oscilloscope through GPIB/VISA (I managed to acquire connection and display response from *?IDN command but that's it, failed with the chart for 2hrs I was given), what controls shall I use, how to configure them etc.

 

best regards

btw, can someone be so nice and upload here vi's from Help / Find Examples /GPIB, also Help / Find Examples / Waveform / Instrument Control Parsing.vi as "example search" doesn't work with my 30 day evaluation of LabView I have at home.

 

best regards

Hello,

      Please confirm that you have downloaded the LabVIEW Instrument driver for your instrument and extracted it into your instr.lib folder.  After doing that, please follow the steps in the Instrument Driver Troubleshooting Guide.  The guide has some good suggestions and links to other instrument control content that you might find useful.

 

Cheers,

Hi,

 

You can easily download them for free from ni.com

 

Anyways, I have them attached.
