I would like to know what does voltages means for DAC channels under FPGA settings in ADI IIO. I want to transmit the sample buffer so i have selected the DAC buffer output under FPAG settings. After selecting the waveform it shows me 4 options for DAC channels.
I have checked the transmitted waveform on Spectrum Analyzer and it shows me different spectrum when i select a pair of voltage0-voltage1 and voltage2-voltage3 while I am transmitting the same buffer.
So, could you please explain what does these voltages means and what is the difference between them?
