GPIB errors tying to connect to a Agilent E8257D Signal Generator (BFFF0011 and BFFF00A5)

[Atencio]

I am getting the following Error in when I call viOpen in my code to try and communicate with a Agilent E8257D Signal Generator: BFFF0011.

I have checked the NI MAX and the Instrument Shows up but when I click on Open VISA test panel I recieve the following: BFFF00A5.

Steps that I have Already Tried:

1. NiVISATullip.dll is check in the VISA Options.

2. The code has been verified on a seperate PC (using the same SigGen) and works.

3. I have verified the Software Version between the 2 PCs are the Same:

    Measurement and Automation Explorer V5.4

    NI I/O Trace V3.0.2

    NI PXI Plotter Service V3.2.1

    NI System Config V5.4

    NI Pal V2.9.1

    NI VISA V5.3

    NI VISA Runtime V5.3

    NI-488 V2.3.1.1

    (Also Labview 2009 SP1 and LabWindows\CVI 2010 SP1, However the code I am Running is in Visual Studio)

4. The ID String for the E8257D is also the Same between the two machines and I am able to run Communicate w\ Instrument and Recive back a IDN? query on both machinces.

I am assumming that this might be some form of Driver Issue or but am unsure of how to check that. Anyone have any Ideas?

Thanks.

I don't understand what you are saying. You say you get an error when you open a VISA test panel but yet you say you are able to communicate to it and get a response.

Are you using GPIB and are you using an NI GPIB controller? The first error is:

Error -1073807343 occurred at an unidentified location

Possible reason(s):

VISA:  (Hex 0xBFFF0011) Insufficient location information or the device or resource is not present in the system.

The second error is:

Error -1073807195 occurred at an unidentified location

Possible reason(s):

VISA:  (Hex 0xBFFF00A5) The interface type is valid, but the specified interface number is not configured.
