How to save data waveform TDS7000 via GPIB

[trosber]

Hi,

I was having problems trying to save data waveforms from scope TDS7000 connected by GPIB and under CVI program. I installed the scope driver and after using the function "tkdpo7k_FetchWaveformToFile", the result was only one line of data (one point).

Any suggestion welcome!

Hello Trosber,

        Can you please confirm that you are using the NI-Certified tkdpo7k IVI Driver?  Also, do the examples run correctly?  Please go through the Instrument Driver Troubleshooting Guide and post the results.

Cheers,

Hello Trosber,

        I installed the NI-Certified tkdpo7k IVI Specific Driver and could not find a function with the name "tkdpo7k_FetchWaveformToFile". If you are using the NI-Certified driver, I recommend that you code the File I/O seperate from the waveform acquisition.

Thanks Nathan for your quick answer. I am using another driver, tkdpo7k but manufactured by Tektronix (not supported by NI). I have already programmed functions for the TDS3054B scope without any issue, but saving is not well solved (I think).

Where could I find any examples of saving waveforms into a PC, using this type of driver?

Thanks again for your help.

Hello trosber,

        The first place to look for examples is Example Finder (Help >> Find Examples...).  It contains a couple of File I/O examples that you might find useful.  If none of those help, please consult the NI Developer Zone.
