Siglent SDS2000X HD, missing Features and Bugs

Got from here:

does not link too. you get to siglent main page.
must be some restricted area we folks can't access ?

Wenn tautech are linking to int.siglent I must click twice on it, first click redirects you, closing it and click on it again.

is it possible to decode channels 1-4 as hex value ? the decode analysis seems to work only for digital channels ?
and I did not find how to display pure hex values, without any i2c or spi or else protocol.
should be the same problem on non HD models.

You will find it from Decode main menu/Bus Display.
Quickly snapped screenshot attached.

Can you please explain in more detail what you mean?

[kripton2035]

I don't have the digital probe. I would like to use the analog channels to display a decoded hexvalue from these channels only.
and they don't have any protocol, just display the hex value that the 4 analog channels represent.
it seems you are forced to choose a protocol among i2c,spi,uart etc..., you can't have no protocol, just hex values displayed ?
like a basic logic analyzer ?
it should be "grouping" on a bus, but seems you can only make a bus from a selection of digital channel.


seems I will have to use sigrok to do that. ... once sigrok will be able to connect to the scope with LAN...

Oh like a 4 bit digital bus...?
No,you cannot do that. 
You can trigger like that (logically from analog channels) but paralel decode is only for digital channels... Sorry.

It would also be nice to have access to the file manager and the files stored in the scope like a screenshot made with the save button,
from the web interface.

What you can do is that you can map windows share on the scope, so save goes directly to server (or PC)..

[kripton2035]

yes I've seen that, but I think it would be more user friendly to do it the other way, from the web interface
you press save on the scope each time you want to have a screenshot, it's faster than save to a network drive you have many buttons to clic
then go to your computer, and download all the saved screenshots at once.
what do you think ?

Some models in webserver mode offer a virtual Save Screenshot button that ports screenshots directly to your browsers download folder. SDS11/1204X-E certainly has this feature.

[kripton2035]

not ideal too as my computer is quite far away from the scope.
better (for me at least) to save directly on the scope, then download all needed screenshots once I am on the computer.

You might need to set up a folder with File Manager and use Save/Recall to direct the screenshot to that folder then when at the PC grab the whole folder.

[kripton2035]

yes, but as I said above, this involves many clics before the screenshot is saved
pressing the save button once for each screen capture is far easier and faster.
I don't think implementing a file download from the web interface should be that difficult.


I could do the save button, then use the file manager to copy all the screenshots to the network drive
again, I don't do scope firmware programming, but implementing a file download from a web interface must be easy ?

No it does not. You map drive and make it permanent. And then you need to save to that mapped folder once, and all following saves go into that folders.

So map folder, one save with menu to mapped folder, and then you only keep pressing Save button....

[Martin72]

I think after 4 pages it could be the time to get all wanted features and (maybe) bugs together in a table as a oversight.
Maybe the forthcoming weekend I´ll do it.

That's something we need explore as a required functionality that certainly could lead to a feature request.
I only have SDS6000A here currently but I expect it has the same functionality as the HD but I'll try to find time to dig deeper into what functionality is currently available.
Give the beta testers a chance to explore this and maybe propose a request to Siglent as it might cover a # of models.

Oh is it that simple, need to explore this.....

Well, I like things optimized...

Summary of the thread so far, post will be edited the next days with links to the posts.

Bugs (or not):

- Bode Plot: After ending this, system falls back but awg (int/ext) remains on with a signal.
- Bode Plot2: After ending, system fallback is not proper, previous user settings on the channels won´t be fully resumed.
- Eres: When active, bandwithlimit caused through this will not be shown in the dialogbox
- Saving screenshots message : Must be closed manually, should be closed after a few seconds automatically.
- Filemanager: Can´t recognize the saving space on a usb stick before, will do saving until stick is full and then aborted it with a failure message
- Timezone: Setting a timezone will be "forgotten" in some cases.
- Mousepointer "Mini Bug": Different pointer design before/after screensaver was active.
- Digital channels: Very slow updaterate of 16 wfms/s (SDS2000X  plus : over 2000)
- Probe detection: When using the default button, everything will be resetted, but probes ratio won´t be setting correctly, you have to disconnect and reconnect them for detection.

Wanted Features:

- 4 Mathchannels instead of two
- "Printing" in Black&White only possibility
- Bode Plot speed up, it´s one of the slowest on the "market".
- Bode plot2: Phase unwrap function)
- Acquisition: Implementation of LP/HP/BP filters ( should be already done with the first FW update @TopQuark?)
- FFT: Logarhytmic X axis
- FFT2: Power/voltage density Y axis units (dBm/rt Hz, V/rt Hz)
- Bode Plot3: Channel selection on external awgs
- Bode Plot4: Add SCPI commands for controlling the Bode Plot function and retrieving data.
- Bode Plot5: Enhanced Features
- Measurements: Possibility to change the digits of shown value from 4 to 2 or 1 after the comma.
- FFT3: Scaling, when in spilt mode the lowest setting is 20dB/div. which is sometimes too coarse, min. 10dB/div. should be possible without getting the signal out of the visible range.
- Measuring of calculated values
- FFT4: "Distortion Analyzer Mode" : Showing the values of the single harmonics in percent, showing the THD in percent.

[mawyatt]

Don't forget the Bode Cal "Thru" feature, this normalizes amplitude and phase measurements something like with a VNA.

Best,

[kripton2035]

another weird thing I noticed today, trying to trigger on an i2c signal
in the signal submenu, you define the scl and sda channels source and you specify the threshold of the signals
if you clic on the "universal" button, it detects for you the level automatically, but not always, the signals must be on the top of the screen
or it fills some values that are too high, and the trigger signal never happen.

[Martin72]

Interesting, can try to reproduce it on my siglent demoboard.
Apart from this, at work we never use the serial triggers, we use edge with defined holdoff because setting the serial triggers made us crazy...
With one exception:
On our newer lecroy scopes this is never a problem.

[tautech]

HD in our hands before it goes to a customer.
Clock and timezone seem stable with latest V1.2.1.1 FW. < now proven otherwise.

Defaults IMO that need changing, Menu hide = OFF, Save (screenshot) to Include Menu = ON

Negative image Save works OK.

[kripton2035]

can you please try to connect a lan to the scope, then switch off and on and see if the time is still at the same hour ?
and before that select your time zone, not UTC
I have installed 1.2.1.1 FW and I cna assure you time hour is not stable after restart...
