Reading data from hp8902a

[Newbie 530]

Hi,
I'm using Visual basic 6 & NI-GPIB card to control hp8902a.
Setting the hp8902a using ilwrt is fine but when I use ilrd to read the data,I always get a timeout.This problem also occur when I use NI488.2 Communicator.

I noticed that this site do provide hp8902a instrument drivers for labview.

Since I don't use labview,some VB code to would be helpful.

Thanks.

Make sure that you are using commands that the instrument understands. Can you communicate using VISA Interactive Controller? There are some troubleshooting techniques and installation procedures listed at the website below.

You may find the Knowledge Base links below useful for using Visual Basic Examples and Language Interfaces.

There are many instrument drivers at the following website.

If you can find IVI instrument drivers, you can use them in Visual Basic. There is a Knowledge Base (link below) that describes the process.
