[Latest Revision Date] 2024/11/1

[Updated Contents]
v00.01.04.00.02  2024/11/1

1. Resolve the issue of no waveform when uncalibrated.

v00.01.04.00.01  2024/10/15

1. Resolve No waveform in XY mode when rolling down.
2. Resolve No waveform in XY mode after default reset.
3. Resolve When vertical units are in volts and a probe ratio is set, trigger and decode thresholds are incorrect.
4. Resolve Menu labels are too short after AUTO.
5. Resolve MATH scale does not follow after setting V/A probe ratio.
6. Resolve Waveform disappears.
7. Resolve Measurements are calculated only once at a 50ms time base.
8. Resolve System crash when modifying all measurement sources under extended time base in measurement settings.
9. Resolve Screen grid settings are ineffective.
10. Resolve Incomplete waveform display when adjusting the time base to enter scan mode in XY mode.
11. Resolve System crash after enabling all measurements and performing default in scan mode.
12. Resolve Abnormal horizontal offset when switching from roll to scan at 200ms horizontal time base.
13. Resolve Waveform does not refresh when switching from channel one to channel two in SCAN mode.
14. Resolve Abnormal color of options in "Source" and "Modify All Measurement Sources" in measurement settings.
15. Resolve Channels do not automatically turn on when modifying all measurement sources.
16. Resolve Waveform does not refresh with multiple stop and run actions in SCAN mode.
17. Improve self-calibration pass rate.
18. In engineering mode, add build time, WPU, and SPU.A to *IDN? response.

v00.01.04.00.00  2024/09/13

1. MATH vertical gear is not an integer, and the offset is not 0
2.the FFT unit in MATH is dbm/dbV, but only dbV is displayed
3. Add new model DHO824
4. Added storage depth option 50M for new model DHO824
5.  When the vertical gear is selected as A, the probe ratio needs to be displayed as V/A
6. Solve the problem that XY can't be opened
7. Fixed the problem that oscilloscopes other than 824 models could not display waveforms

Upgrade DHO804 to DHO824: https://www.eevblog.com/forum/testgear/rigol-dho800900-new-firmware-v00-01-04-00-02-2024111/msg5723799/#msg5723799

TimFox:
No sign of improvements to Bode plot function software.

norbert.kiszka:
I don't understand why we need three separate topics for each software.

BUG #1
- With the CH1 probe connected to the calibration output, sometimes when pressing the AUTO button the time base is miscalculated.
Update: https://www.eevblog.com/forum/testgear/rigol-dho800900-new-firmware-v00-01-04-00-02-2024111/msg5724199/#msg5724199


mrisco:
The DHO804 can be upgraded to DHO824 giving 200MHz maximum bandwidth and 50M memory depth.
For that, it is just necessary to use a binary editor to change one of the model strings to DHO824 in the tool rigol_vendor_bin to enable the DHO824 as a selectable model using the command:

--- Code: ---rigol_vendor_bin -M DHO824
--- End code ---
