Needing Help GPIB and VB.NET (Semiconductors)

Post by hoolarm4 » April 15th, 2017, 6:55 am

Hello to all, I am new here and I need you help about a project I m working on.

First of all, I m an electronic engineer from Greece. :)

My project is to build a program in Visual Basic.NET on Visual Studio 2015 for I-V , C-V , MOS measurements + leakage current about semiconductors via GPIB.

I have install the KUSB-488A driver and I have also check the examples on it.

Now, I have to add some references in VS for GPIB communications? Also, I need some other driver or .dll to communicate with the devices through Visual Studio?

Is too complex or not to implement it? :?

Is there any documentation or someone that can help me for VB.NET?


The equipment :

QCV-meter (Keithley 595)
- (Keithley 485)
LCR meter (Hewlett-Packard 4275A)
Amplifier (±120V ±1200V)

Thank you for your time 8-)

Hi,

You do not mention your version of Windows.
Have you been able to validate the function of the KUSB-488A? Use the trtest.exe or other utility software that would install with it.
Can you successfully send a command and read response from any of the instruments?

The KUSB-488A is rather old, so first want to caution that the Windows version needs to be old too to be compatible. Check the release notes.

In Visual Studio, you will need to set the target for x86.
In VB.NET, you would add the *.vb module to the project.

Hi, and thanks for the reply.

Im using Windows 7 Pro x64.

Right now, I can't test the communication between the instruments. I ll do it this week.

I don't have any problem with the KUSB-488A. My PC can recognise it.

Also, I found and opened the examples from the installation folder. But, I don't know what to do next.
