XP E3634A power supply

[paulb1]

Hi all,

I normally use NT, but I loaded CVI on XP and my E3634a power supply is not communicating through CVI,  is this an XP thing?

Will I need new drivers for my instruments?

Many thanks

You can use Measurement and Automation explorer to look at the interface to the power supply and see if you can communicate with it.  If it is GPIB just do a scan for instruments and see if it shows up.   You also want to check the return code from the driver you are using to open the connection to the supply.  Possible issues you could be having are; no visa driver loaded,  you need to configure a logical device name to match the name being used by your software, IVI class driver not loaded.

I used Measurement and automation and can see the power supply, I can also send commands to the supply and receive info back, but through CVI nothing happenings. I'm using the same drivers as I do with NT, but just wondering do I require and changes to run on XP

I have migrated a number of programs from NT to XP and never had to change anything.  Unless you are using logical device names (not physical names), and do not have the logical names setup on the new system, it should work.

Hi Paulb1,

There shouldn't be any problem when moving from one OS to another and using the same code.  The only problem I have ever seen is timing issues, due to the new OS being faster.   However this does not look like the case here as it seems like CVI cannot see the instrument at all.    

Can CVI see any other instruments?  What order did you install your software in your new machine?  If you installed your driver first and then your ADE, MAX would be able to see your device but CVI would not.  Try reinstalling your 488.2 driver.
