--- Quote from: joeqsmith on December 29, 2022, 06:19:33 pm ---Thanks for the PM. First thing I need to do is some research. This will take some time. Odd they would use 100Mb now days. Here's the old WM after installing the 1Gb card. Looks like it was around 200ms to transfer 10MB of data at 420Mbps. Old tech. To your point, I am not attempting to get the screen to update fast, just move blocks of memory into the PC for post processing. It may be a case where I just need to get one and write some software for it. --- End quote --- Using source CSV files ? If so Siglent now have a smaller BIN file format that reduces download times and when it's on your PC there is a small BIN to CSV executional you download from within the scope to convert back to the more normally used CSV. IDK what normal file size reductions are obtainable with BIN downloads other than for most captures it's a significant and worthwhile step to go through. Been a while since I used it but it's darn simple IIRC. https://siglentna.com/operating-tip/oscilloscope-binary-data-format/ This obviously reduces the need for blindingly fast LAN connections. I have some other bits to maybe share in a PM later. |

Someone had asked about running an FFT with a PC using the data from a scope. From what I remember they had provided some constraints and were basically looking for how fast it could run. I think I joined the fun with the WM. Looking for the code, I don't see it. I could certainly toss something together if you would like to try an A/B comparison. I'm pretty much limited by that 400Mbps transfer rate. |

I meant the software I used when I demo'ed the FFT. |

About network interface speed: don't stare yourself blind on that. A DSO won't be able to use 100Mbit to the limit |
