Data acquisition with Agilent DSO6014l

[GG RA]

Hello,

I want to read the data of a shown graph of an Agilent DSO6014L oscilloscope with LabView 8.5. Agilent provides a set of device drivers and I use the "Read Single Waveform.vi". This works, but it gives me only 250 data-points and that is not enough, because I want to do a FFT afterwards. Has anyone worked with a scope of the 6000 series or any other oscilloscope and faced the same or similar problem? Or has someone a idea what the problem could be?
I post my VI so you can have a look. Version 8.2

Thanks for your answers!

Hello GG RA,

I took a closerr look to the device driver and I found some examples shipped with the driver. I think there you can get a lot of informations. Use in your application a modified example, often that helps. If you did not find the right setting you have also another possibility. Try to use the VISA vi´s and you can work with the device speciffic commands of the DSO6014L. You can find all the commands in the detailed specification of the device from Agilent.

Hope that helps. Best wishes

Thanks a lot for you suggestions. I already found out how to solve the problem. One has to modify the number of points that will be read at the waveform acquisition. To do it one can send the command   :WAV: POIN:MODE RAW. That enables you to set the number of points up to 8,000,000 by the command   :WAV: POIN xxxxx. So your chosen number of points are acquired.
