Listen, I just updated the firmware.. Now, if you click on "file converter" on the web interface, it lets you download a file converter (wow!), in .zip format.
When you unzip it, it shows two files. A windows' .exe (the converter's executable), and a Readme text file. The Readme says:
"We provide two tools to convert bin file into csv file:Bin2csv.exe and Convert_bin_to_csv_file.py [etc, etc..]"
There is no python script. I'd like to have it.
Is it the same for y'all? No python converter in the .zip file??
Thanks.
So after all the waffling today have you installed the latest firmware yet ? You should. The Timezone bug is a nothing and can be worked around with setting a UTC zone.
I just did! See my other complaints above
Seriously, I understand Siglent not wanting the customer to mess with the OS. And yet....
Run/install Bin2csv.exe on your PC.....then you get options of how to manage the downloaded from DSO BIN files....you know those ones much smaller than CSV.

Until the bug will be fixed, shouldn´t last long.

Guess is ~Chinese New Year, some 8-9 weeks away.
Normally a lot of FW updates are released then.
I´m curious about the next (second) HD update, but that´s an other topic.

Thing is that the .exe is windows only, while a .py would have been cross platform, and embeddable.
Would you please check if it's absent in your 2kX+(s) too?
I also only get the Windows executable.

So you sourced your copy from the webserver button, correct.
Have a look in the scopes Save/Recall menu too or in File Manager.
Will have a hunt soon.
Calibrating my HP3310A, I have just thought about:
How can I measure THD with a SDS2000X+?
Would have expected this as measurement of source F1=FFT.
My HP35665A just shows the value in %.
This would be a huge effort when e.g. the table could present at the end the THD.
Actually there´s no alternative from counting the shds together.
When one of our tested inverter shows a suspicious THD on the analyzer, we connect a scope at the output and watching the shds on the FFT screen.
Table function allows you to display the shds in numeric form, as mentioned above it would be cool if the scope would display the thd also.
EDIT:

Also for me, no python script in the zip.

This looks not bad and available in Windoze, Mac and Linux versions:

Ahhh..
We should set it again on the wishlist, it´s one of the "most useful" wishes IMHO..

It seems to work, thanks (tested with just one file though)
Just linked this in another thread for Peter:
https://www.researchgate.net/publication/362542224_Total_Harmonic_Distortion_THD_analysis_utilizing_the_FFT_capabilities_of_modern_digital_storage_oscilloscopes
Thats a nice comprehensive paper, Rob, thx!
I did the adjustment by just minimizing the peak levels of the harmonics.
Before and after the adjustment.
" alt="" width="300" class="bbc_img resized" />
Minimal tweaks of the two potis involved gave a nice improvement.
The manual of the 3310A just stated a "Distortion" of better than 46dB below the main signal.
As they suggest a HP331A for the distortion measurement, I checked that manual. The 331 just filters away the main frequency and offers the remaining signal to RMS measurement.
Will have to read the paper above first to think about a valid calculation.
Or did I miss a sophisticated filter funtion of the SDS2000x+?

I was thinking you might be able to use the Math Equation editor to build some THD analysis formula.
Please don't ask for guidance as my algebra is abismal.
Can´t imagine you can calculate this via editor, for THD you must summarize all SHDs, how can you determine them separately from the FFT in the editor...
Way better would be an implementation directly in the FFT menu like it is in the PA.
Haven't played yet, but:
Can I get the peak list exported, e.g. zu CSV? Then it would be easy in xls.
Edit: Now I have played:
I found no option to chose the part of screen content to export.

IIRC you can save in BIN format, much smaller than CSV and download the internal BIN2CSV tool to convert the BIN file back to CSV.
Also in FFT you can use the Peak Hold but unsure how that effects the file capture.
... and a question:
What is ths 'Para Switch' for in the Save menu?
CSV output seems to be identical on and off.
Edit: RTFMRM
(... most recent ...):
>>CSV Data
Saves the waveform data to the external memory in ".csv" format. After
selecting this type, you can touch the
ParaSwitch to determine to
include the scope configuration parameter information (horizontal
timebase, vertical scale, etc.) or not. Touch the Save All Channel to
save all displayed waveforms on the screen or select the Source to
save. The available sources include C1 ~ C4 and F1 ~ F2. <<
