| Nov 3, 2023 at 21:45 | comment | added | SteveSh | In your 2nd picture - the one with the VGA and ADC - where is the pulser itself and where is the piezo transducer? | |

| Nov 3, 2023 at 11:54 | comment | added | SteveSh | Can you separate the returns for the two transducers? | |
| Nov 3, 2023 at 10:48 | comment | added | SteveSh | And actually, what you've sketched out is pretty good from an EMI standpoint as the current from each pulser will follow the path a least impedance (inductance, in this case), which is one that minimizes the loop area. | |

| Nov 3, 2023 at 1:21 | comment | added | SteveSh | Where is the ADC in your picture? | |

| Nov 2, 2023 at 18:57 | comment | added | Andy aka | I'm really unsure as to what the problem is that your are describing or whether it is something that you think might be a problem. Either way, be succinct and hit the nail on the head and ask a question that clearly defines the real problem you are facing.. | |
