SIGLENT SDS1102CML - First Impressions
rf-loop:
2)
No need full version. Runtime package is enough.
http://siglent.freeforums.org/post145.html#p145
runtime 5.1.2: (afaik, Siglent recommend version 5.1.2)

- one wink for do what ever waveform (manually, or can also do string with some program.
You can store known waveform to USB. (do not use LongMem for exercise)
then open this file with some nice HEX editor, example HDD hex editor neo (free version). Very fast you find where is waveform samples data. In sample data string, do not use 0x00 (#00). If there is zero, there is not any kind of trace (first in bottom line is 0x01)
Note that sampling speed base in data is of course what is used when you first store .DAV
If you want do zero line.DAV for working first do .DAV
Set example 10us/div
just for example 500mV/div
center vertical
you see horizontal line.
Save .DAV to USB
Read usb with hex editor.
edit data in address area from #03ff to #2bf2 #2bf1 to value #80
Edit address #2bf3 #2bf2 value to example #c0 #cb (+3div) and also example next 10 memory positions same. And then after this point to #53d0 agen all #80
(in this case time between memory positions is 10ns (100MSa/s)
Now you have straight line, then center of screen there is 100ns long peak.
do not make other changes in file lenght etc and other memory position equal as before.
Load it back to scope. You see one around 100ns spike center of screen. Zoom just turning horizontal speed to it. Change display to dots. Zoom until you see every dot.
Remember to do work DAV first with this settings you want use later after you download file to scope.
Samplerate is what it was in original DAV (yes these can also edit but better that not change before know what do)
So, you can "draw" what ever signal shape and then display these with scope.
After this exercise you can do what ever signal.

THANK YOU VERY MUCH rf-loop :-+!
rf-loop:
Here is what can play using example some hex editor. There is clear zero line and middle is short -3V and then +3V and back to zero line.
First, load attached setup to scope, and just after then load attached waveform to scope.
Signal area (CH1) there is #3E8 to #A3E7 (do not change out of this area things)
(note: signal area is different if scope use 40k memory (in single channel and 1GSa/s speed)
All other exept middle pulse are set for vertical value #80
One vertical div is 25 so 3 div is 75 ( #4B) so +3V pulse top is #CB becouse voltage setting was 1V/div.
Btw, vertical baseline position is byte in address #30 where data is now #80
(if play with these, save and load with same scope settings becouse dav file included settings do not set all exactly right)
With this dav file it is easy to make what ever signals to scope screen and example inspect how sinx/x work (or other fun things). (yes Sinx works right even if first feel there is something wrong - not)
There is 10us/div, short memmory, sinx/x off (x) etc.
Signal is zero exept 2 samples -3V and 2 samples +3V just around center of screen.
With this speed sampling speed is 100MSa/s
After loaded to scope, zoom in/out just turn horizontal speed more fast.
(note that in stop mode of course there is not trigger time position fine adjust process working)
If edit these files with example HexEdit do not change other area than signal and keep care file lenght is equal also of course.
One disclaimer. I have not tested if these works with earlier FW version!
(Tested and made with FW 5.01.02.22 only)
Setup file filetype .TXT change to .SET
Dav file type .TXT change to .DAV

Thanks, again,
I'm right now playing (and studying manual ;)) with my scope, I don't know what scope you have (I assume it is 1702 or 1102CML); my HW version is: 11-62-3.3 and software ver: 5.01.02.13. I found that there is no date/time adjusment under Utility menu - should this scope have this, not essential, but nice feature? I saw, on LeCroy's copy of SDS1072CML there IS that possibility - there is time and date down-right at screen. Furthermore, I saw picture of Siglent SDS1072CML also with date and time!? Maybe sellers put that image from 2000 series? But, anyway, there is no reason that this is missing!
OK, for now I found that I can't adjust 1GSa/s for single channel (ch.A!) (just up to 500MSa) whatever I do! Only when I turn channel B (with nothing attached on it) - here it is! Then I turn off ch.B and continue with ch.A, this time with maximal speed! One of bugs...
I only have my scope 1 day, I'm trying to be more familiar with it, so I will try to do what you said, sounds interesting, thanks!!! :-+
See you later!

EDIT: I realise now you have FW 5.01.02.22 ? Is this newer version than mine? Or you just have different scope, but if it is Siglent there is no newer version than mine on their website, except if you have 2000 series or so?
Huh, there is no Siglent's 2000 series, I mixed this with Rigol, sorry. I meant Siglent 1xx4 (4-ch.) version, but I see there is picture of SDS1102CML WITH time/date right on Siglent page!

Later there is coming Siglent SDS2000 (soon) and later more.
Afaik, SDS1000CFL models (2 and 4 channel) have real time clock. SDS1000DL/CNL/CML do not have real time clock circuit (it is not FW it is hardware).
This time when I play with this DAV file I use:
SDS1102CML
FW:5.01.02.22 (not just yet available from Siglent download center, I hope they update download center asap so that peoples can update new FW)
If you change horizontal speed to fastest speeds and LongMemory is selected. It do not shut off LongMemory and it use then max 500MSa/s. It is not bug. (but yes there is still some other small bugs in some samplerate related things)
If there is only one channel selected for use (CH1 or CH2) and if horizontal speed is 50ns/div or faster and if memory selection is Normal then it use 1GSa/s. And in this case it also use 40k memory (becouse these two channels memory is combined together, not one after one but interleaved becouse here also 2pcs 500MSa/s ADC blocs. (both 500MSa/s ADC's are also made by interleaving several 100MSa/s ADC's)
In long memory mode it can not use 1GSa/s at all. This is normal, it is also in other similar principle working scopes, as example Hantek 5000B and Rigol DS1000E etc. All these have half speed LongMemory. 1M or 2M.
Siglent have 2M (in two channel mode 1+1M)
