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…

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

Hello,

is there data available concerning the phase response of the analog inputs of your ADCs?

Hi,

       We brought your AD9278 Evaluation Board and AFE HSC_ADC_EVALC board , and following the   "AD9278_79_EVB_User_Guide.pdf" , setting power, setting the SPI control.  Then we  using an signal synthesizer generate one 1MHz / Vpp=5V sine wave ,…

%The following dlls are required for using the library.
%These three dlls are needed in the same directory:
%HadBoardApi.dll
%HadSdpSupport.dll
%sdpApi1.dll
%If you have installed VisualAnalog these dlls will be in the VisualAnalog
%install folder…

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…

   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.

d_REG1 <= 24'h00_00_18 ;
d_REG2 <= 24'h00_04_0f…

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?.
Best regards Romas

Hello All,

Please help for my question about Xilinx Zynq-7020 interfacing AD9278 (12 bit, 8-channel, up to 65MSPS) or AD9670 (14 bit, 8-channel, up to 80MSPS).

1) Is Zynq-7020 (Artix-FPGA Fabric) able to interface and sample AD9278 or AD9670 8-channel…
