Currently selected one?

That would make sense, but no - its not possible to select any data channel. The channels are having a fixed (configurable) distance to each other in vertical direction, its not possible to move them separetely.

With vertical voltage knob you can select which one is red and with vertical position knob you can move it's order... Reorganize numbers so to speak... So you "grab" No1 and move it between No5 and 6

You figured that out just by playing with the controls??

It's not very intuitive, that the channel selection is not possible by mouse click...

Thats amazing - THANK YOU!!

And pressing the position knob resets the D0-D15 order again...

This behaviour is similar to Keysight.... So I just tried to do the same thing...

One more thing: if you touch a Digital icon on bottom of the screen, there you can set position and distance between the channels...

Here a wish, siglent can fulfill when they´re having nothing else to do or lost a bet or got a apprentice who needs a task... :D 8)
Decoder-feature:
Decoding of IR-transmitting codes, Like RC-5 and others for checking functionality of remote controls.
Add support for the SDS2000X HD to Sigrok.
https://sigrok.org/wiki/Protocol_decoders
https://sigrok.org/wiki/PulseView
You can do this with any of the existing supported scopes.
Done ! : https://www.eevblog.com/forum/testgear/new-sigrokpulseview-hardware-support-(siglent-sds-hd-rigol-dho800-)/

Feature Request:

Show both High and Low levels on triggers with multiple values. (Currently appears to only show the last edited value)

Feature Request (again):

Add ascii decoding to parallel bus.

Add ascii decoding to parallel bus.
This is in Siglent's pipeline already. There are some higher priority tasks around, yet we'll get that eventually.

In this context, do you perhaps know whether the Wfm's/sec display will come at some point?
It was included in the list "back then" by electronic hobbyist, namely SDS800X HD, but this and the ASCII decoding are things that can be rolled out across all models.

Sorry, i don't know the status of a trigger rate display. Maybe "electronic hobbyist" can give us an outlook...

But it goes without saying that I had requested the ASCII decoding for all DSOs that support the SPL2016 logic probe.

What about expanding displayed trigger information? Is that on their list yet? It would be really helpful in screenshot info.

I cannot know what's happening through other channels (customer feedback, contributions from support staff, internal evaluation etc.), and I'm not aware of any such request from the beta team.

And – just for clarification – discussing and requesting a feature still doesn’t mean that it’s “on their list”. Whenever I say something is on their list, I have a confirmation from Siglent, together with the corresponding change request ID.

In any case we would need to make the trigger info box much wider in order to fit additional information. I could request this (as I'm always easily convinced that we should get as much information on the screen as possible), yet we need to be careful to not overdo it and leave some space left for the channel info boxes 😉

The trigger box should be wider, but doesn't need to be. They waste plenty of space even in the tiny box using full words when they could use vector symbols or abbreviations like other companies do. In my attached example, they write Positive. They could have a + symbol after runt, and the the H level under the L. They could use arrows for rising or falling, etc. Bigger would be better; more efficient would also be better.

The word Stop in the Trigger box is also kinda redundant- it shows that at the top of the screen too. The box is not being used efficiently.

I attached a couple simple ideas for the trigger box, though the R&S box info is nicer.

Another option would be to have a detailed Trigger popup window. Could be similar to the Counter box, or the Ref table in the attached screenshot.

Thanks,
Josh

I've got the confirmation from Siglent development team that your proposal is accepted. They will try to pack more information into the trigger info box.

Can somebody please put in a feature request to make it possible to change Trigger Coupling frequency values (preferably arbitrarily)? Or is that not possible?

Thanks,
Josh

Sure! The SDS2000X HD datasheet says:

Quote
Trigger Coupling:

C1-C4:
LFRJ: Attenuates the frequency components below 1.17 MHz
HFRJ: Attenuates the frequency components above 660 kHz

EXT:
LFRJ: Attenuates the frequency components below 7.5 kHz
HFRJ: Attenuates the frequency components above 250 kHz

I want the ability to arbitrarily set those frequencies to anything I want. For example, Low Frequency Reject (HP Filter) frequencies below 5kHz, or 20kHz, or 800Hz, or whatever the cutoff might need to be to eliminate a specific waveform I don't want interfering with triggering.

In the attached example, Math filter is used to isolate two waveforms on CH1.

I want the trigger to be able to ignore either one of those waveforms depending on what settings I choose. Having the frequency not hardcoded, as it currently is, would make this trigger type significantly more useful / powerful.

Thanks,
Josh

Josh,
thanks for explaining.

I'm not sure that is even possible....
It is hardcoded now so it can be simple and optimized. Triggering is realtime operation running of full speed datastream.

I think it may be possible to be added as a feature because the hardcoded frequencies 1. don't match (internal vs. external), and 2. aren't standard filter numbers like for the channel filters. It seems they were chosen at least somewhat arbitrarily and should be able to be replaced with a variable input. Or, a new trigger coupling filter with a variable input added, but that would seem redundant.

Thanks,
Josh

ETA: Check out nctnico's post with channel filtering: https://www.eevblog.com/forum/testgear/new-keysight-infiniivision-hd3-oscilloscope/msg5663417/#msg5663417

That would be nice too. 😉

Nico's post has nothing to do and don't confuse it with channel filtering.
HP and LP filter in trigger works on full data rate and it is at it is because filter was chosen that was fastest and it landed approximately where it did.

As for filters in math, they are have current characteristics because of number taps in implementation. As Martin said, it is similar to LeCroy in that regard.
Other manufacturers did something else, and they are either decimating or use some nonstandard filtering method. Siglent uses proper FIR filters.
Filter on Keysight 3000T can filter lower frequencies with same sample rate, but it's characteristics is not documented at all and it is basically visual aid.
Micsig I have also have limits when sampling at higher sample rates.

Do not get me wrong. I will raise this question with Siglent. I personally would like if filters on Siglent scopes would be more powerful. But maybe this was resource limit? I don't know.

Awesome, thank you!

Speaking of actual channel filtering, do you think they might add 50M and 100M to the channel filters? Mine goes from 20M directly to 200M, but a couple stops between would be nice.

Thanks,
Josh

Well, those are actual hardware filters. They are proper anti aliasing filters before ADC.
If I need more control I use ERES.

Isn't there also an actual 100M filter? It started life as a 100MHz scope, I thought there might be a proper filter for that too.

Bode still doesn't remember some previous session settings after power off.

Sweep was set to single, comes up as continuous.
Load was Hi-Z, comes up as 50Ω.
