agilent mixed signal osc

[train33]

hello,

i'm trying to develop a driver for the Agilent MSO6034A oscilloscope: it must be able to acquire a screenshot, load a preset stored on the computer and save a preset from the osc's memory to computer.I'm currently using the GPIB port but i can use also USB.

I had downloaded the latest driver here and i also have installed agilent I/O software suite.

The problem encountered is when i send a command to the Osc, the command is often ignored,works sometimes and error messages like "query unterminated" and "header error" are reported.

Errors happen when i use the supplied driver, the agilent I/O softwares and commands sent simply via labview.

So i don't know where the problem comes from...the driver?Agilent VISA?conflict between NI visa and agi Visa?osc?computer?

thanks to anyone who will reply..

Hello train33,
        Which Instrument Driver are you using?  We have a Project-Style LabVIEW Plug and Play Instrument Driver here.  The errors that the instrument is returning are usually a result of incorrect commands being passed to the instrument or the commands not having the proper termination character.  If I were in your same situation, I would just use NI-VISA, recognize the MSO in MAX, and use the LabVIEW Plug and Play Instrument Driver that I linked to.

Cheers,

NathanT
