I found a file called test in the root of the voltcraft that intrigued me.
/fpga.exe w 40 2E8E
/fpga.exe w 41 0050
/fpga.exe w 41 0600
/fpga.exe w 41 0614 #VGA 1
/fpga.exe w 16 6af0
/fpga.exe w 17 30
/fpga.exe w 18 6af0
/fpga.exe w 19 30
/fpga.exe w 1a b010
/fpga.exe w 1b 30
/fpga.exe w 1c b010
/fpga.exe w 1d 30
/fpga.exe w 1e 6c10
/fpga.exe w 1f 30
/fpga.exe w 20 0000
/fpga.exe w 21 30
/fpga.exe w 22 D000
/fpga.exe w 23 30
/fpga.exe w 24 6c10

/fpga.exe w 42 0
/fpga.exe w 2d 0
Does it mean something to you?
yes it does. From what i know the fpga.exe is a executable which is accessing the FPGA registers,
it will be also used by /dso/app/testacq (which seems to be test app for DST3xxx and DST4xxx series only).
the output of fpga.exe is like
----------------------------- fpga.exe use guid --------------------------
-- fpga.exe w addr dat : write single data to addr --
-- fpga.exe r addr : read single addr, single data --
-- fpga.exe R addr len : read single addr, mutil data, d_disp, 10/line --
------------------------------- end ---------------------------------
however, this is one of these tools which are on my "check what they doind some day" ...
It seems that Hantek removed it from latest hardware models (hw1007x555583e9) anyway.
The reason why they did can be more the fact that they trying to hide something
and less that they "care about ppl haveing these nee models with new fpga design"
When i ran it on 83e8 and 83e9 models it is did exact the same, so what.
If wish to play with this a bit, check attached (which is missing on Voltcraft as well),
e.g. the line /fpga.exe w 41 0614 is controling VGA offset from ch1.
When yu check the schematic you will see what (mainly S&H)can be manipulated by changing of some FPGA registers values.
