New Rigol HDO1000 12-bit DSO - BUGs

[dominicc]

Sure its working on dho1000, though not amazing. Depending on the memory depth the visibility may go to nothing.
Maybe try turning off hires too.

Still not working here at 500Mpts, 5GSa/s at 200ns/div with infinite persistence (or any lower persistence) and high-res off:

Turn down the memory depth, not up. Or set it to auto.

When displaying a reference waveform, overlaid together with an actual channel waveform in "stopped" mode, zooming in on the time base may lose the phase correlation between reference and waveform at certain time base (especially vernier mode) settings. F/W is 02.12. When the time base is running, this discrepancy may momentarily also show up but gets corrected upon the next trigger. See attached screenshot for an example. Anybody to confirm this?

Firmware 2.13 is now  available on Rigol's website !

And they fixed my main grudge, the decoder levels jumping around ! 

Here is the complete changelog :

0.02.13 2024/03/27
      - Fixed the problem of deleting files when copying the same files.
      - Requirements for optimizing the total time for oscilloscope delivery, configuration, and reading.
      - Fixed the problem of crash when LAN is not connected and click Apply.
      - Fixed the problem that after passing the test screenshot, it cannot be stopped.
      - After fixing the default, *IDN? cannot read the project version number.
      - The problem of not closing the project version number lxi/identification.
      - Fixed the issue of statistics not being reset when moving the measurement cursor.
      - Fixed the problem that the measurement value of the moving cursor area is not updated after STOP.
      - Fixed the problem of occasional no waveform when booting.
      - Fixed the issue of the waveform disappearing in small gears after a pause.
      - Implementation of USB external keyboard requirements.
      - Fixed the problem of obtaining Math waveform error.
      - Fixed vertical scaling mask error by testing.
      - Fixed SPI timeout triggering problem, also for four-channel mode.
      - Modify the problem that ultraLab cannot connect to the server after shutting down and restarting.
      - When the Zoom function is turned on, the cursor adjustment area is not limited to the Zoom window.
      - Modify the offset range below 50 ohm and 500uV/div to solve the flip problem.
      - Fixed the problem of failure to modify the settings of measurement source B.
      - Fixed the problem of window transparency and failure to load the last value.
      - Fixed the problem of error in saving screen waveform to csv and SCPI command to obtain waveform in Math filter operation.
      - Fixed the problem of crosstalk caused by adjusting vertical offset.
      - One-click to open the measurement items required by the user and realize the functional requirements of the trigger source tracking channel.
     - Error displayed when modifying the measurement cursor for multi-source measurement.
     - Fix the problem of IIC SCL threshold and SDA threshold random reset&trigger level line random jumping caused by probe ratio at 10X gear.

Weird that it's dated March 27th...

I wonder when will it be available for DHO800?

I noticed that on my 1072 frequency measurement is empty until I fit at least 2 cycles on the display using horizontal scale. Is this a bug or a feature?

Feature.

One cycle is a pulse, not a signal with a frequency.

Hi,
I have an annoying issue with RS232 decoding in ASCII format on my DHO1074.
What do you think is the best way to contact Rigol for support.
Did any of you had success mailing to help@rigol.com ?
Thanks,
Michel.

I'm sure they'll pass your email along to Rigol China but don't set expectations too high after that.

Hi,
Mail to help@rigol.com done!

The issue :
I have a DHO1074 with the latest firmware (00.02.13).
When decoding a RS232 signal, everything works fine when displayed in Hex, Dec or Bin. Also, everything  works OK in Zoom mode with these display formats.

But when I set it to display in ASCII format, below a certain timebase setting, the decoding data does not follow the trace when it is moved with Horizontal position (see screenshot below).
Also ASCII decoding data is not displayed properly in Zoom mode.
