So installing the firmware and '3 capacitors/resistors' upgrade will get you the sweep speedup but will result in degraded performance without the other hardware changes. The noise improvements (S21 noise floor) is due to other hardware changes though.' V2Plus firmware is still open source and you can read the code to see how the sweep speed is increased. ' V2 plus has many more hardware changes than the published '3 capacitors/resistors' upgrade, which doesn't completely upgrade your device to v2plus but allows you to get the sweep speedup.

Use Goggle translate to translate from Japanese to English. Cho45 has provided detailed instructions for the entire modification at: In addition to the hardware modification, my understanding is that you will also need to also change the bootloader before the new firmware will work properly. So, I'm trying to take the lazy route by finding out if someone has already built a ready-to-go firmware for such a combination. for installation of the compiler for the arm platform. I could of course roll my own, but at first glance, I'd have to spend a bunch of time with my current distribution to add the needed libraries, etc. Now I'm in need of firmware which is compatible with this modification to take advantage of the faster sweep rate. I modified my SAA2N (compatible firmware for the 4' V2.74 from blackmagic) to the V2+ spec by performing the capacitor/resistor mod to upgrade from V2 to V2+.
