gpib usb HS - Acquire Wfm format directly on PC

[Sylvain1978]

Hello,

Is it possible to acquire via a GPIB USB HS

the curve in wfm format on a scope (without floppy).

I have a tektronics 744.

Thanks.

Of course it's possible. That's the whole point of GPIB control. You don't mention which programming environment you're using so all I'll do is point you to the Instrument Driver Network where you can do a search for the particular model you have. There are drivers for LabVIEW and LabWindows. If you want to do it yourself, it's a matter of learning the instrument programming commands from it's manual and doing VISA Writes and Reads (or GPIB Writes and Reads) to setup the instrument and retrieve data.

i have try your driver. Many things can be done. Wonderful,

but you can save directly on your pc the wfm curve.

You can control and make a autosave on a floppy with the " Tek7** Sav/Rcl Waveform" functions.

but you need always to have a floppy on to save on the floppy.

I want if it's possible to save directly the .wfm on my computer

I'm not sure I understand your problem. I'm assuming that whatever software you're running is acquiring the waveform by transfering it from the scope to the pc. After that, all you have to do is save it wherever you want. This would be a function you write in your program and is not a function of the instrument.
