Recognizing Drivers

[dieciduej]

I am trying to learn how to use SignalExpress 2.5.1 and one of the problems I have encountered is communication with the test equipment.  Following the various webcast videos the one key thing that is missing is where/how to install the proper instrument driver or to be more exact how to get SignalExpress to recognize it.  I have installed the drivers using LabVIEW’s Find Instrument Drivers and Install.  LabVIEW itself will see my test equipment and allow me to control it using the driver’s examples.

Now I just need SignalExpress to give me the right chose of driver when I create a new IVI session.  I chose the proper Resource Descriptor “GPIB0::7::INST” but all I get is the NIDMM or the NiScope driver choices for the DMM and oscilloscope respectively.

Can someone point me to the proper webcast or can help with my situation.  Thanks.

Hi,

I've downloaded and installed the evaluation of signal express 2. However, it cannot find my device, ROHDE SCHWARZ UP350 Audio Analyzer

Is it not supported, or configuration is needed? How?

were to find: LabVIEW’s Find Instrument Drivers ???

Thanks.

I have solved my own issue of finding and loading the IVI drivers for SignalExpress.  When I searched for the drivers I also use IVI in the search pattern and chose the driver that specified IVI and that seemed to solve the issue of SE seeing the drivers.

But now I have driver compatibility issues with some of the equipment.

Hello,
To control your instruments in SignalExpress you will have to download and install the required drivers.
Please read this article to proceed.

Let us know if this answers your question.

I have figured out how to find the drivers for SignalExpress (SE) on the web and I have downloaded and installed them with no problems.  Now SE shows the drivers for my equipment the new problem is a question of driver and hardware compatibility.

The first problem is with our oscilloscope, a Agilent 54622D.  The driver I downloaded and installed in NI’s ag5462x (Ver 2.210.18).  When I try to communicate with the oscilloscope I get the following error:

ivi_IviScope Configure Acquisition Record.vi<ERR>

Driver Status:  (Hex 0xBFFA0010) Invalid value for parameter or property.

Primary Error: (Hex 0xBFFA0010) Invalid value for parameter or property.

Secondary Error: (Hex 0xBFFC0002) Parameter 2 out of range, or error occurred while setting Parameter 2.

Elaboration: Time Per Record

The oscilloscope’s screen keeps flashing a QUERY Undetermined.

The second error is with the function generator, a Hewlett Packard 33120A.  The driver I downloaded and installed in NI’s hp33120a (Ver 5.0.11).  When I try to communicate with the oscilloscope I get the following error:

ivi_IviFgen Initialize With Options.vi<ERR>

Driver Status:  (Hex 0xBFFA0001) Primary Error: (Hex 0xBFFA0001) Instrument error detected.  Call the PREFIX_error_query function and examine the error  code and error message parameters for additional information regarding the error.

I can see and use the equipment with LabVIEW with no problems and SE also sees my Agilent power supply E3631A and Agilent DMM 34401A with no problems.  So once the issues with the oscilloscope and function generator are settled all will be happy.

Hello Claudiomas,
Your device does not have drivers on NI IDNET, we have support for other audio analyzers here, but unfortunately not for your device.

I realize the RSchwarz UP350driver for LabVIEW6 does not work for SignalExpress.
so i ask today by phone if they can find solution

so they will check .
Thanks
