I modified the firmware to save some fpga/waveform buffers to the SPI flash and one of the buffers, the one used to calculate all the measurements (pkpk, min, max, ...), contained 1200

Not bad!  :-+ :clap:

But if the Y resolution remains the same, it's probably not extremely useful.
Do you manage to get to the whole buffer to see more of the timeline?
Like you can see in the zoom tool in the upper area?
That would perhaps be a real advantage
Sorry if I'm asking stupid questions. I have no idea what is possible this way.

In zoom mode the firmware requests/reads memory from the FPGA two times instead of one, using a different time base, so it can draw the upper and lower waveforms, so what you see on the LCD is probably all the data there is.

I did find a feature in V1.3.0C that does not exist in V1.2.8C+, a "real time" auto mode that can be activated by long pressing the AUTO key.

--- End quote ---

I found a "Gain calib" (V1.2.8C) and "Factory calib" (V1.2.8C+ and newer) mode, that can be actived from the "Meas" CH2 menu by long pressing DOWN.

I also found a reset option for some of the settings that can be activated from the "Set" menu by long pressing the AUTO key. All FW versions.

Yes, ptluis called it "continuous auto mode"

Yes, i had already updated the cheat sheet. See "DSO2512g_plus_cheat.pdf"
