I am a beginner/intermediate electronics person. I have never bought electronics components before and only worked on Arduino/Raspberry Pi stuff. Hoping to get some guidance, so that I know what I am buying and why I am buying it and how to setup a hardware setup to get an analog signal.
Background: My setup currently has 2 ultrasound transducers. I will pulse one of them and then collect output from the other. My problem has to do will collecting the output. Normally, one can do this via an oscilloscope, but I want to gather this data and store it/transfer it to my laptop, so that I can run digital signal processing on it.
I am trying to get a signal that is coming out of an ultrasound transducer at ~1MHz +/- 5V. It is a sinusoidal analog signal that is generated from the ultrasound transducer. I suppose I would like a resolution of 10 bits (should be good enough for +/-5V). And for Nyquist sampling, I would want something sampling at probably 3MHz to capture the signal effectively.
I am wondering what sort of ADC is out there that can do this. If so, where can I find this and how should I go about buying it. Would you be able to provide me with some links and specific examples? I go on google and search and I feel like I just get bombarded with different results I don't understand.
