NI-SCOPE Soft Front Panel Errors

[bmann2000]

I'm unable to capture a 10kHz square wave using NI-SCOPE SFP.  The error I receive for manual config and auto-setup is -200580 Requested Vertical Offset invalid.

Test Panel in MAX can capture the signal without errors.

My setup is PXI-5154 Slot3, Chassis PXI-1031DC, Windows Vista, LabVIEW 2009, MAX 4.6.0f1.  Test input 10kHz square wave, 4Vp-p connected to Ch0 BNC of 5154.

Hi bmann,

What is the resource descriptor in Measurement & Automation Explorer (MAX) for this device?  Is it the same as any other devices that have previously been on your system?

The 5154 does not support vertical offset, but other devices (such as the 5152) do support vertical offset.  The NI-SCOPE Soft Front Panel (SFP) will use the resource descriptor to identify devices.  If no configuration is found for a device with a particular resource descriptor, then the SFP will run an auto-setup on the device.  However, if the SFP does find a matching previous configuration with the same resource descriptor, it will try to use that same configuration.  This is where I believe you may be getting the error. 

If you have a 5152, you can check the "vertical offset" parameter in the "Device Configuration" window--it sounds like this is the parameter that the SFP is trying to commit to the 5154, and the NI-SCOPE driver is throwing this error.  For a 5152, this parameter should show up, but for the 5154 this parameter should not show up.

Could you try re-naming the device in your system to something unique?

Let me know if this helps.  If not, it could be another issue--let me know what version of the NI-SCOPE driver you have installed if that's the case.

yes, the resource descriptor was the problem.  A while back I moved the 5154 to another slot for an experiment with the PXI_Star trigger, I then moved it back to Slot2.  NI-SCOPE SFP was linking to the old resource descriptor.

To fix the problem I had to delete the old resource descriptor in MAX, then rename the remaining resource descriptor.

Many thanks.
