12 years agoIf you are quite familiar with ADC and DAC, you will see that we need to adjust the gain value which is to adjust the converter into the amplitude of our signal. Well, don't mind if you don't understand what I've just said. I'm not a good explainer.
In other words, a signal source usually includes DC and AC component. It's like you have a sine wave but it is shifted up or down around the zero. It is because that sine wave is added to a DC component. That is very "annoying" in signal processing as it consumes power when processing, causing heat, reducing the accuracy of the represented binary, adding truncating noise to your signal when processing. Any way, that statement means, you can only put AC signal into you SMA cable (for ADC) and create an AC signal (DAC) Also, when you apply the signal onto your daughterboard, your DC component will be filtered out. And by they way, I dont think you broke your board, it's maybe because of the contact between your board and daughterboad was not tight. Try to push them toghther harder
