• AD9278-65EBZ/AD9278-80KITZ/AD9279-50EBZ or Evaluation Board and HSC-ADC-EVALCZ Data Capture Board 采集信号,频率偏移

    您好,

          我们采购了AD9278评估套件,并按照AD9278_79_EVB_User_Guide.pdf的操作指示一步步操作,我们用信号发生器从CH_A输入了1路10MHz的信号,当运行了FFT的例程后,出来的能量最大的信号是7.63MHz,并在10MHz处没有信号;同样输入了1路5MHz的信号,当运行了FFT的例程后,出来的能量最大的信号是3.8MHz;输入了1路1MHz的信号,当运行了FFT的例程后,出来的能量最大的信号是0.78MHz。

          目前查阅资料没有找到有效的解决办法,请求你们的帮助…

  • AD9278增益问题

    您好,目前我们在用AD9278做检测设备,发现个现象,当增益增加到某个值时(最大值的一半),信号最大,再往上增加,增益下降,这个怎么处理、

    谢谢

  • AD9278-50EBZ + HSC-ADC-EVALCZ Acquisition from MATLAB

    Hi

    I have been trying to configure the AD9278-50EBZ and the HSC-ADC-EVALCZ for data acquisition.  I found the MATLAB script for acquisition on the AD9253 using the HadBoardApi and tried to adapt it (see code attached) to my hardware however, I have a challenge…

  • how to config ad9278 to generate test pattern

       I use the following command to write register of ad9278 through SPI. It seems it doesn't work.

    We have scoped the spi signals which look good. Please help to check if I missed something. Thanks.

  • RE: AD9278 with HSC-ADC-EVALCZ drivers and documentation

    Hello.

    To work in Matlab x64 you need to add the following lines of code in before start making method calls to the DLLs:

    NET.setStaticProperty('HadBoardApi.HadBoard.Compatibility',HadBoardApi.CompatibilityFlags.('HadSdp…

  • AD9278 dinamic range

    Good afternoon
    We have problems with the AD9278. Unable to use the whole dynamic range.
    AD9278 distorts RF signal like in attached files.
    Maybe our connection/programming are wrong or this is normal operation for
    this chip?.
