Problem with Agilent B2902A and LabVIEW drivers

[filmartinelli96]

Hello,

I am controlling Agilent B2902A with the Labview drivers.

Recently, I updated the firmware of Agilent to the latest version (3.4.2011.5100). However, upon upgrading the firmware, the Labview driver stopped working properly. When trying to run the examples provided in the library, the program cannot properly run the initialization block and goes into a timeout error. 

I have downgraded the firmware to the previous version and it seems to work properly again. However, I would like to make it work with the newer firmware version because the instrument with the old firmware gives me some measurement problems occasionally.

Does anyone have any suggestions?

Is this a VI based driver or rather using an IVI driver. In the case of a VI based driver you could step into the driver VIs and check what goes wrong. It could be just the version string that it checks that returns a different format. A quick check for that theory would be to try to disable the ID Query on the Initialize VI.

But please note that this ID Query is not just to be fancy. It is there to make sure you are trying to talk with the right device. And if they changed that Firmware Revision string so much, it may be that they changed other things in the communication protocol that your driver may then stumble over.

You changed the device FW and unexpected changes occurred.   Click the link above and ask them what they did and how they tested it.
