Hello everyone,

I am working with zc706 fmacomm5 dev board and am having some issues that you may be able to address.

First of all am downloading the latest AD reference design from:

Build that, produce a new BOOT.bin and load it in my SD card, which in turn will be used in the board.

Then what I have to do is to receive in a particular frequency X of sampling rate Sx and bandwidth BWx and transmit in another Y with the same sampling rate and bandwidth.

So, I set all these parameters on the ADI iio oscilloscope.

The problem is that I don’t see in the output of my transmitter, the image of the input to my receiver.

For example, if I receive at 100Mhz and transmit in 150 Mhz then in the output of the transmitter I am  seeing a signal centred at 150Mhz and this is not going to be shifted If I change the received frequency to 105Mhz or 110Mhz from 100Mhz.

Fyi, I am using the ADI iio oscilloscope’s FFT analysis tool as a spectrum analyser.
