Below figure tell us how to measure the noise of AMP. Here we used scope to measure the noise. Below is my questions:
1. I'd like to know the model number of this scope, for measure nV grade signal, this type of Scope should be expensive;
2. If I haven't the scope, I think using the 24 bit ADC to measure the AMP output noise is a good method, that is: connecting AMP output to ADC's input, and analyze the ADC's output noise. Any suggestions about this method is appreciated.
