When i ADC analog signal with output impedance of about 32ohm the received digital signal is cut off (1 positive half cycle)
How to log the signal correctly

Re: Error signal when Log Analog signal

On ADI-2, try one step higher Reference Level.

Re: Error signal when Log Analog signal

I increased the ref level to 24 dBu, however the signal is still clipping at positive cycle (not happening with negative cycle)

Re: Error signal when Log Analog signal

Try a signal from a completely different source.
Connect ADI-2 Pro’s output to it’s input and play a sine wave.

Check left and right input seperately.

i use signal generator and adc log is correct

So ADI-2 Pro is OK then, right?!

In this case please change the title, add “SOLVED”, to help other readers understand.
