Hi, all! This is my first impression by quick testing Rigol MSO4024. Please, sorry me for my bad English.
I want to create this post as early
REVIEW - Rigol DS2072 - First Impressions of the DS2000 series from Rigol for separate discussion of MSO4000 and DS4000 series of oscilloscopes. Now I have created little report for Rigol's distributor in my country on Russian language "Rigol MSO4024 sw00.02.zip" (
this is only report, not firmware!). Now this report is translating by distributor to Rigol company.
This is some bugs from upper document with very little description (sorry).
Known Firmware Bugs/Issues
(red indicates latest FW version available, italic indicates requires for testing - please, inform me about results)
1. Very slowly work with USB-disks. Writing to 2GB disk *.png 45KB ~18...30sec with ~50% filled USB-disk! With clean and formatted drive you take ~8...10sec
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]2. "Print" button can't save all screen, only signal and grid.[FW v.00.02.00.00.04]4. Not informative progress-bar, when disk writing is active
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]7. Fonts with eng words has little character interval, bad smoothing. File manager's font with big character interval for Unicode's Cyrillic symbols
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]8. No nonvolatile through-counter for saved files (see comments in my RU report)
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]9. Considerable inconvenience. Channels measurements is by FIFO-principle: when you adding new measurement, old left are deleting
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]14. Considerable inconvenience. Very primitive cursor measurements for XY-mode
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]16. Not stable V_RMS-measurements for >10 periods of unchangeable sin signal on different time-bases (~2..3%)
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]17. On little overload channel V_RMS is not readable
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]18. On little overload channel signal form like slightly mirror image from up and down (as OPAMP reverse phase effect)
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]20. Some big freezes with FFT math
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]21. Multi-function Knob change value, when you are press on it (this is bug on all Rigol oscilloscopes)
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]29. Automatic menu hiding work in spurts
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]30. Moir of signal with big time-base in some cases
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]31. As for DS2000. ANTI-ALIASING does not prevent waveform aliasing to any degree, on some big time-bases signal is absent completely, freezes of scope.
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]32. As for DS2000. There is a bug when using DOTS mode with AUTO memory depths @ >= 5us/div. It affects the waveform update rate (much reduced) - and can also affect the visible display of the waveform.
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]33. Near as DS2000. Changing intensity of signal, when enabling second channel (see pictures from my RU report)
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]34. Auto power on, when external power 220V cable disconnect/connect to oscilloscope[FW v.00.02.00.00.04]37. HiRes mode. On time-base @ >= 5ms/div signal is absent with CH1 only enabling, but freq-counter working properly (100-1000Hz sine). We can see signal, when CH2, or CH3+CH4 are been enabling.
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]39. Offsets for channels on 1mV/div ~0.3...0.5mV (see pictures). Ext probes is absent, channels with internal 50 Ohm
[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]22. Not mine. Freezes with logic analyzer (LA) at I2C mode:
Scope comparison during I2C decoding Part 1 and
Scope comparison during I2C decoding Part 2[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]23. Not mine. Phase shift of result sequence and phase jitter for LA at parallel mode
RIGOL MSO4000 Parallel Trigger and Decode[FW v.00.02.00.00.04] / [FW v.00.02.01.00.03]24. Not mine. Not working LA decoder after power off/on for SPI-mode:

Edit 1. Formatting post, adding new firmware, correcting waveform rating (thanks to
tized), added new screenshots
Edit 2. Autopower is with disable option. No bug #34. Adding Table with Bandwidth in High Res mode (memory=AUTO), light green - x2 better, than DS2000
Edit 3. Reorganized mediafire folder, added Changelog.txt link and firmware upgrade procedure. Edited bug #1. Bugs #9, #14 is considerable inconvenience now.
Edit 4. Reorganized mediafire folder, added Frequency response tests and Pulse tests links, corrected FR images
