R&S FS300 driver, "Could not load front panel"

[rabarbar]

Hi,

I'm developing remote control software for Rhode&Schwarz FS300 with LabVIEW 2011 Student Version and VXI Plug&PLay drivers downloaded from official site:

http://www2.rohde-schwarz.com/en/products/test_and_measurement/spectrum_analysis/FS300_FS315-%7C-Dri...

I've followed the instructions from Remote Control Manual,but among functions listed in driver LLB some of them cannot be opened, what is reported with message:

"LabVIEW: Generic error.
An error occurred loading VI 'XXX'.
LabVIEW load error code 3: Could not load front panel".

Although their icons exist in Function Palette, every attempt of dragging them to Block Diagram ends with "XXX.vi was not found" message, as if they were missing.

Drivers were installed on two different computers and the same problem occured on both.
Could it be a matter of corrupted LLB file? What could be a solution?

Thanks,
rabarbar

The driver uses express vi's and I believe the student version cannot edit these.

I think that's not a matter of student version, because other vis from this particular driver are available to use as project subvis and work properly...

Did you try to open the VIs directly from the file system, e.g. Open RSSIFS VI Tree.vi?

[rabarbar]

Apart from:
RSSIFS Configure Trace Mode.vi
RSSIFS Configure Trace Detetctor.vi
RSSIFS Getting Started.vi
every other vi can be opened with LLB Manager (both Front Panel and Block Diagram can be loaded). When I open RSSIFS VI Tree.vi there are question marks instead of icons of vis listed above.

Which LabVIEW version do you use?

[rabarbar]

I use LabVIEW 2011 Version 11.0.1.f2 (32-bit) and so is my OS..

Those files seem to be corrupt. You need to contace R&S to see if they can fix the problem with their code.

[rares.c · Accepted solution]

Well, if the LabVIEW drivers don't work with your version (and with drivers that old, it can happen), you can try use the DLLs. From what I can see, the installer from the R&S site also gives you the DLLs. Here is how you can do that.

I'll check that,  please be patient.
