I have a major setback for this analog devices called as AD9635, High Speed converter evaluation platform. How do i collect raw data from the Data capture board?

HI People,

               The High speed converter evaluation platform, bought by my external supervisor has been pass on to me to find out how to get the raw data. The data from what i get is processed by data capture board, using the Microsoft excel, i find out that the sine wave computed by the data is not a continuation of sine wave but rather in between there is a cut of data.

Another setback that i encounter is the data is not a complete set, there will be a few sets of data that will be missing, during the processing time of the data capture board. Kindly advice me on how i can get the complete data, what can i possibly do to get hold of the complete data. Your help is kindly appreciated, as i cannot progress any further due to the setbacks i m facing.

  • Hi Hus,

    To confirm, you have already used the "Save To File" option in VisualAnalog, and this is not enough for your need? If you use the "Continuous Run" feature along with "Save To File", you can save a lot of data. The data is saved on your PC storage as .csv file.

    If you need a more direct way of saving data, here is the very limited information I have related to the Labview interface to the AD9635 capture board. This is just the first step and you will need to do more to make this work.


    For AD9635, you will need the 32bit version of LabView.

    You will need to locate these three dll files:

    • HadBoardApi.dll
    • HadSdpSupport.dll
    • SdpApi1.dll


    If you have already installed VisualAnalog, you have these dlls on your PC. These can be copied from the VisualAnalog install location. For example, on my laptop, they are located in C:\Program Files (x86)\Analog Devices\VisualAnalog .
    If for some reason you cannot find these dlls on your PC, you can run this executable: ftp://ftp.analog.com/pub/HSSP_SW/HadBoardSupport/HadBoardSupportSetup.exe to load the dlls.

    Copy these dlls to a known location of your choice.

    In your Labview script:

    • Include the path to HadBoardApi.dll . The location will depend on where the you installed/copied them.
    • Include the path to the FPGA program file. In the typical VisualAnalog installation, the path is something like: C:\Program Files (x86)\Analog Devices\VisualAnalog\Hardware\HSC_ADC_EVALC\ad9645_high_freq.bin
    • It is possible that the script needs to be run from the same directory that the HadBoardApi.dll resides.

    With the above completed, Labview should be able to communicate with the HSC-ADC-EVALC FPGA board after Labview is setup properly. Unfortunately I do not have Labview to try this with. If you are experienced with Labview I hope you will be able to make progress with this.

    Thanks,

    Doug
