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…
On the AD9278, if I program the various device registers via SPI and then put the device into STANDBY, do the registers retain the programmed value when I bring device out of standby? Same question for PDWN.
Good afternoonWe 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 forthis chip?.Best regards Romas
Hello,
is there data available concerning the phase response of the analog inputs of your ADCs?
Best regards,

I am using the analog front end chip "AD9278/AD9279" with 50MHz sample rate. However, I have signal integrity problem on the trace of data output pins (DOUT+ / DOUT-) to my FPGA(output data frequency is 50MHz x 12bits / 2 = 300MHz in my case). I would…
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
I am currently using an AD9278 with a HSC-ADC-EVALCZ board, and I was hoping to interface to these with either a C based code or Matlab, and I was wondering if there any drivers one could get with appropriate documentation?
Thank you in advance…
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…
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…
