There really is no need to go slow. When I'm tweaking a circuit, I don't want to wait for over a minute to see the results of the changes. Heck, you can simulate a circuit faster nowadays. IOW: There is a tradeoff between getting the lowest noise floor and making a feature that is useable. In most cases you'll be working in situations where there is more than enough headroom. |

Just to ruin it further I'm not sure your LARGE (in size) contributions to that thread were actually comparable to what mawyatt provided as their example: https://www.eevblog.com/forum/testgear/bode-plot-torture-test/ Fast = short time captures and less noise rejection, cant get around that when keeping other conditions the same. |

I guess you missed the fact that the RTM3004 offers at least the same results in the same noise / disturbance conditions while needing about 10 times less time. It is not my fault mawyatt created two threads to discuss closely related topics. |

There isn't enough time capture the data that would suppress the interference. I'm guessing your configuration was not comparable to the original post... in that other thread where you could be discussing this rather than trying to blame others for your inability to maintain context. :clap: |
