SDS800X HD Bug Reports + Firmware

From eTobey's side, it might feel like he is doing work for Siglent?

Actually, some kind of "bug bounty" program would be a nice touch. Users who find and characterize bugs are providing a service to Siglent and to the user community, after all.

Dear Siglent -- I would settle for an SLA1016 logic probe, ideally with an extra set of the better grabbers!

Actually a function generator would be my preferred item at the moment. Also i wouldnt find so much bugs then, which is something me and others would prefer anyway.

Issue:
Field of no response.

There is a region, where no clicks or dragging is working. Anyone else having this problem?
You can see the extends, if you look how the mouse pointer changes its appearance.

Two things I have noticed so far..

1) Math does not appear on the ribbon menu at the top of the screen like on the SDS2000XP.  This means it's not available through the web interface.

2) You cannot enter the IP address is 206.108.0.132, nor the IP address 216.239.35.4  I can enter the 2 and the 0 of the first octet, but then it just stops.  I can enter 199 in the fist octet, but not 206 or 216.   200, 201, 202, 203 are all okay, but not 204, 205, 206, 207, 208 or 209 (214, 215 ..)

Very strange.

Has anyone else noticed these?

It is.
Math is done on an active channel by activating a Math channel.
Press the + and select Math for the new channel, then select its source.

[BillyO]

It is.

Ahh, RTFM then, eh?

It just looks and works so much like the SDS2KXP I made a silly assumption.

Thanks Rob.

[KungFuJosh]

RTFM

Rob's favorite line. 😉

[tautech]

It is.

Ahh, RTFM then, eh?

Actually I booted one to check and as you say there is no room for a Math dropdown due to the small display....actually it's one of the 1st things spotted when I got this one in early Feb as the white model SDS1000X HD I already had and its 10" display does have a top ribbon Math dropdown menu.

So rather than press the front panel Math button I already knew how to add a Math channel with a mouse but for this check so just used the touch display and the webserver will be the same.

One thing that I like is copy to Ch..
You need to look into SPI?
Enable all 4 ch, Set 1st one, copy 3 times and off you go...

Those CH tabs are full of wonders....

New issue: Measurement wont work on parts of the captured waveform:

The measurement does not measure, when the gate is at different positions. Watch the measurement tables when the gate is moving.

[Martin72]

What are you doing there?

[shapirus]

I really, really hate to post a reply here, because it will make the thread start popping up in the "new replies to your posts" section, and I have no immediate interest in Siglent scope bugs, but I finally have to, it's just unbearable.

@eTobey, pretty please, read this: https://marker.io/blog/how-to-write-bug-report
and this: https://www.chiark.greenend.org.uk/~sgtatham/bugs.html
and this in general: https://www.google.com/search?q=how+to+write+a+good+bug+report

I mean no offense, truly. It's for everyone's good.

[eTobey]

I thought it is quite obvious what is happening. I have edited that post.

[2N3055]

We get you are showing something about measurements.

Still no explanation what exactly do you think is wrong and why do you think is wrong.

I edited that post (with the video), and put the explaination in there.

I cannot reproduce any problem.

I made a signal on AWG:
Pulse, repetition frequency: 45.45Khz (22µs period), pulse width 150-300ns modulated with random noise.
Scope 1ch, slope trigger, 20µs/div, 2GS/s
Measurement gate width: 31.4 us
I guess that is close enough.

I found no problem with scope.
Fact that at certain points you stop having results for certain measurements is because of the fact that to establish measurements of period you need to select time period where there is a full period inside.

[eTobey]

I cannot reproduce any problem.

Me neither   

Should have saved the setup.

[eTobey]

I now could partially reproduce the issue. Only the width+ measure does not work now.
Maybe it is the way how to captured the waveform:
First single shot trigger, then activation of cursors and measurement. Scrolling the waveform to the right?

See attached the setupfile.

[eTobey]

I have an issue:
I captured a frame in roll mode (auto mode - stopped), the trigger position is right in the middle.

I can only change the scale from 200ms/div to 50ms/div. 

It somehow happend again:
I only changed timebase and hit start/stop. A restart solves this issue.

OP has been updated to the latest status. According to feedback from eevblog, 1.1.3.6 has at least merged the following bugs and improvements.
Here are my test results, if you have any different opinions, please let me know.
(The list does not include all modifications, such as Optimize waveform capture rate, Optimize Self calibration speed, and so on.)

Resolved Bugs:
3. After rebooting, the vertical gear of FFT did not restored.
https://www.eevblog.com/forum/testgear/sds800x-hd-bugswanted-features/msg5396141/#msg5396141

4. There have been crashes when using CAN and IIC decoding.The probability of reproduction is relatively low. - The revision record includes this item
https://www.eevblog.com/forum/testgear/sds800x-hd-bugswanted-features/msg5396960/#msg5396960

5. The universal knob can only set the history frame when opening the menu, and should be able to operate the list when closing the menu.
https://www.eevblog.com/forum/testgear/sds800x-hd-bugswanted-features/msg5424557/#msg5424557

6. When the menu disappears, the universal knob light is still on, and at this time, the universal knob is used to change the brightness of the waveform.
https://www.eevblog.com/forum/testgear/sds800x-hd-bugswanted-features/msg5401697/#msg5401697

7. Measuring with cursors on a history frame is impossible, since moving the cursor changes the history frame simultaneously.

8. Math Function dialog automatically closes after channel change.

12. Sequence is restart when menus are opened and closed.
https://www.eevblog.com/forum/testgear/sds800x-hd-bugswanted-features/msg5426579/#msg5426579

13. Scale number overlaying others.

14. The setting of the trigger type edge(When edge slope is set to alternate) influences the qualified trigger.
https://www.eevblog.com/forum/testgear/sds800x-hd-bug-reports-firmware/msg5467114/#msg5467114

15. When adjusting the level for source A in "trigger delay", and setting it below low level of signal, acquire stops.
https://www.eevblog.com/forum/testgear/sds800x-hd-bug-reports-firmware/msg5462833/#msg5462833
https://www.eevblog.com/forum/testgear/sds800x-hd-bug-reports-firmware/msg5466322/#msg5466322

16. Most trigger settings for the Delay trigger are lost upon reboot.
https://www.eevblog.com/forum/testgear/sds800x-hd-bug-reports-firmware/msg5466322/#msg5466322

Resolved Improvements:
6. The Save button under the Bode Plot does not work. Modify it to save the image according to the Bode Plot print settings.
https://www.eevblog.com/forum/testgear/sds800x-hd-bugswanted-features/msg5399735/#msg5399735

24. When using the knob with cursors, the cursor menu opens when pushing the knob. This is totally unnessary.
https://www.eevblog.com/forum/testgear/sds800x-hd-bugswanted-features/msg5414138/#msg5414138

25. When typing with the keyboard, dont close everything, when you click on a non keyboard area. Solution: have a margin around the keyboard.
https://www.eevblog.com/forum/testgear/sds800x-hd-bugswanted-features/msg5414924/#msg5414924

30. The checkbox for percent and count in the histogram window are to small, and easily missed.

I can not see any improvement here. Using the webinterface, i can not recognize a margin around it. Also i am a bit dissapointed, that there is yet not a single special char (spacebar), that lets you write proper filenames, without doing 2 additional clicks.

Many thanks for the summary!

We had an extended discussion on FFT behaviour in another thread, and Performa01 eventually concluded that there was problem when the FFT sample rate is not equal to the acquisition sample rate: https://www.eevblog.com/forum/testgear/sds800x-hd-review-demonstration-thread/msg5494570/#msg5494570

Has this already been addressed in the 1.1.3.6 firmware as well?

This problem still exists and has been added to bug No.18. Hope that subsequent versions will resolve the remaining bugs.

I though the problem with the SCPI export was in the list...

SCPI export of decoded frames/bytes is incomplete:
There are 78 bytes that are captured, and that appear in the list on the scope, but the export does cut it short.

I tested it well with NI VISA, it seems that the web is limiting the return of data. You can use Python to read the data and save it.
My opinion is that the web is not a good analysis tool, such as obtaining decades of megabytes of data, Python is a good way to process data.
