Error -1073807330 ocured at Ke24xx Initialize.vi (Keithley Driver)

[vicky1]

I am able to control other instruments connected to my Agilent 82357A USB-GPIB card (such as 34401A, 3631A, TDS2024 etc) but when I hook up Keithley 2400 and run its driver it gives me error -1073807330 at Ke24xx Initialize.vi. I have already done Tulip setting in MAX and i'm using Agilent I/O library version 14.

Also if I run the same code on a 4 different PC's with NI USB-GPIB card, I'm able to control all the equipments including Keithley 2400. So I think this has something to do with Agilent's 82357A. Any help will be appreciated as we have only one Keithley 2400 and I have to make it work on the setup using 82357A

Hi Vicky,

Do you have any more details regarding this error? Try running just the initialize.vi and see exactly what VISA function is throwing this error. Also, try communicating with the 2400 using VISA interactive control.  Run VISA interactive control from Tools>>NI VISA in Measurement and Automation Explorer, when the VISA Interactive control menu opens, double-click your interface and device, this will open a new session window.  Select the write tab, and hit execute, and then select the read tab and click execute.  If the device is communicating correctly, it will return the device's identification. If not, it will return an error. I hope this helps, post back with any new information.

Hi Ted,

I had tried running initialize.vi alone and it gives the same error (I am using Ke24xx.llb which i downloaded from NI). I am using Agilent's 82357A GPIB-USB, hence i'm not able to run VISA interactive control from MAX. However from Agilent's IO control I'm able to read device identification (*IDN?) correctly.

Hi Vicky,

Could you step through your intialize VI, and see exactly what causing this error?  Use highlight execution, and you will be able to see exactly what VISA function is causing this error. Your error is indicating that a state of some attribute is not valid or supported by the device.  It would be helpful to know what attribute this error is referencing so we could find a possible work around.

Thanks!
