You guys can argue about it with Rigol if you want but the latest version they have is 00.01.03.02.02!
https://www.rigolna.com/firmware/
That is currently the latest from the rigolna.com site. However, the supportcn.rigol.com site has the latest (as of June 2023) 00.01.03.03.00 firmware.
Rigol's firmware download management is a mess. For example, the Rigol NA download page (
https://www.rigolna.com/firmware/) shows the most recent firmware as 1.03.02.02 but when you download it the name of the file you get is MSO5_FW_V1_1_4_4.zip. However, the contents of the file currently do contain v00.01.03.02.02. And the version numbers sometimes are given a leading "00" and are sometimes use single digits sometimes double digits. Sometimes the device is called "MSO5000" and sometimes "DS5000". Sometimes a .txt file in the download archive might be in some encrypted (or otherwise undecipherable) like E-SafeNet or "%TSD-Header-###%".
So confusion is the natural state of Rigol's firmware update process. The release notes in the zip file seem to always accurately describe the version that is inside the archive (if they are readable at all).
The "DS5000(ARM)Update v00.01.03.03.00" archive contains the following files:
DS5000Update.GEL
MSO5000 Release Notes.txt
MSO5000 Upgrade Instructions.txt
MSO5000 升级说明.txt
MSO5000 版本说明.txt
- "MSO5000 Release Notes.txt" file is an unreadable "%TSD-Header-###%" file (Google and the Linux 'file' utility are not helpful in figuring out what a TSD Header file is)
- "MSO5000 Upgrade Instructions.txt" is an English translation of the "MSO5000 升级说明.txt" file. The translation is encoded as UTF-16LE with a BOM
- "MSO5000 升级说明.txt" is the "MSO5000 Upgrade Instructions.txt" in Chinese encoded with the "936 Simplified Chinese (GBK)" code page
- "MSO5000 版本说明.txt" is the "MSO5000 Release Notes.txt" in Chinese encoded with the "936 Simplified Chinese (GBK)" code page
The attached file ("MSO5000 版本说明.translated.txt") is a Google Translate for the "MSO5000 版本说明.txt" since ""MSO5000 Release Notes.txt" is unreadable garbage. The translation looks fine.
Finally, if you want to use the patch for v00.01.03.02.02 post #2470 in this thread has a link (note: I have not downloaded or tried that link, and the person who posted the download link has made exactly one post to EEVBlog):
