Tektronix TDS2014B. The scope free runs just fine under it's own control but under SignalExpress control it repeatedly triggers creating a recording that is discontinuous bursts of data.

Hello,

The main difference I see is the older IVI Compliance Package. Can you please upgrade to 4.5. http://joule.ni.com/nidu/cds/view/p/id/3065/lang/en

Thank you for all the screenshots. They will come in handy if this package upgrade does not help.

[DrElectrode]

Upgraded but no help, same results.

Were the screenshots you attached of a virtual device?

Did you follow the following steps when creating the virtual device?

[DrElectrode]

The screen shots with IVI in the filemane are using the VI. The filenames with live data are from the actual scope.

I will recreate the IVI following the linked instructions. I used those instructions on the 64 bit machine several weeks ago, however, I did not when creating on the 32 bit unit. 

Also, I should have a Tek TDS2014C scope to try Tuesday afternoon.

If the problem is occurring with a simulated instrument, I think we can rule out the scope. Knowing that it did the same thing on a 32 bit machine will be helpful. Testing a different scope will also definitely narrow down the issue.

Just received a loaner TDS2014C and as you would expect, it exhibits the same behavior as the TDS2014B. I have been searching a bit and found some info on non-buffered streaming. I have downloaded and extracted the files from win32fileiovis.zip but now I need to know where to place them and how to access them. That is, if you think that this could help.

On another topic, is there a means of paying directly for telephone support? I am down to the wire (pun intended) on this project and I am suffering.

Hello, thank you for trying that. I'm sorry that this is taking so long. This is such a unique scenario that we are currently getting a laptop with WinXP sp3 set up so that we can replicate it. I have already informed R&D about the issue and they will be assisting me in determining what the problem could be.

You said that this was a trial version of Windows XP sp3? Is there any other unique software installed on that machine?

Pending those results, we can give you a call if we are still not able to replicate the issue.

[DrElectrode]

Correction, Windows XP is not in trial mode. It it the NI LabVIEW SignalExpress Tektronix Edition that is running in trial mode. The trial period ends 12/13/12, so we should be good for now.

[Jacob_R]

So both the simulated IVI Scope and the physical scope managed to work on a Windows XP Professional SP3, intel pentium M processor 1400MHz, 1.40Ghz, 1.5Gb RAM with Signal Express Tektronics edition trial version 2.5.1.

If you Add a Step that Creates an Analog signal, does it work when you view the added signal in DataView?

We may need you to create a technical support report from Measurement & Automation Explorer. This article shows how you can do it.

[DrElectrode]

I get the same results of discontinuous bursts of trace. I have tried several different settings, again to no avail. Please see the attached project and trace files. Also attached is the MAX generated report. I ran it as custom but if this does not cover the info you need, please indicate which files I should include when using the Technical Support report.
