Siglent SDS2000X Plus

[2N3055]

-snip

But I saw you repeating one question about triggering and would like to know if I got it right:
you would like to be able to trigger to a serial digital pattern. Do you mean that in any particular protocol (UART, I2C, SPI, CAN) or some custom defined sequence?

Standard async serial (UART), trigger must take place on specific sequence of bytes taken from the decoder output.

Ok so you want to trigger on a string (a multibyte sequence) ?
2000X+ can trigger only on single character, as far as I know. I don't have one to check so someone with SDS2000X+ correct me if I'm wrong.
In some other protocols you can trigger on more detailed data.

[tautech]

I don't think HD protocol triggering is any different to X Plus or for that matter 5000X or 6000A models.

Some X Plus arrive in the next day or 2......

Ok, I will check further  downloading manuals from official web site.

How about the PC application to manage LA operations, does it exist  ?

[Martin72]

I don't think HD protocol triggering is any different to X Plus or for that matter 5000X or 6000A models.

Me too.
The decoding menus on my HD are 100% identical to the SDS2k+.
And I bet it is identical to 5000X/6000A also.
The decoders are in all cases simply outfitted, to say it in this way.

Do you mean remotely ?
Yes the webserver can do that and probably the SCPI command set too, I need check or you can in the programming manual:

Thank you very much, I just checked the SCPI manual and for what concern LA commands I can only find something related to pattern trigger, it does not seems that you can operate the LA acquisition remotely.

My main need would be to transfer LA acquisition memory to a windows PC in order to visualize, analyze and store it to disk by an existing Windows application.

I think you want to look at the ":WAVeform:DATA" query.  There is an example for downloading the data for a digital channel starting on page 562 of the PDF.

I think you can do that with a CSV or BIN file save.
With the front panel blue Print button we get PNG screenshots to internal or external storage but within the Save/Recall menu we have more filetype options which we can operate locally or remotely and even save to specified addresses.
The File Manager feature in the Save/Recall menu is quite powerful.

As far as getting trigger on a multiple byte sequence of data  (and assuming Saleae is not what you want to use), you might want to consider using a microcontroller with a simple firmware program that monitors the serial port and when it sees the data sequence you're interested in it toggles a GPIO that the oscilloscope or logic analyzer you're using can trigger on.  I'd think this would be fairly straightforward to code up since sample code that reads/writes a serial port is generally readily available for most any microcontroller.

With a setup like that, you'd be able to use whatever scope or LA you want.

I don't know how easy that'd be compared to whatever capability Saleae's tools have (do you need to write an "HLA" to be able to trigger on an arbitrary byte sequence?).

Yes, you are right, it's possible to select digital channel as source data :

:WAVeform:SOURce D0
:WAVeform:DATA?

For some reason i was convinced that :WAV command group was related only to analog wavforms, but i was wrong   

Ok, time to study in detail SCPI manual ...

As I explained in another thread, MCU board programmed on the purpose is the system that I used till know, but i would like to change approach to be more flexible on the field and because now i'm developing many application on half duplex mono wire serial buses and I need to get actual sampling data of the line to spot bus collisions.

Of course i have other user cases for the DSO iteself, otherwise the purchase would not be justified to sniff serial line.

If LA command set includes what I need, i will add the LA kit on sale.

I'm reaching out to more experienced (than me) SDS2000XP users to get some help.

I'm trying to set the time zone and I'm also trying to set up network storage, however I can't seem to get either to work and neither one is in the manual.  Has anyone been successful in getting these features to work?

Hi,

Actually there is a "Timezone bug" present, I guess it´s "valid" for all touchscreen-models (2k+, 2k HD, 5k+, 6k A) because of more or less the same software.

[BillyO]

Well, I was certainly not going to pull out the "B" word again.  The last time I did it created an international kerfuffel.

So that explains the undocumented time zone feature .. it can't be set.

How about the network storage? 

[bingo600]

How about the network storage?

From the 1.5.2R1 - RelNotes

Code: [Select]

Fixed
 Network storage only works for SMB1.0

What vers are you running ?

[BillyO]

SMB 1.0.  My NAS is rather old and does not support anything better.

Is there any documentation about setting it up?  It is, or should be, fairly simple unless they have done something weird.  I'm using:

Drive letter: Z:
Directory: //[server_name]/share
User: [server_name]/[user_name]
Password: [password]

Result:  Mount directory error: please check your parameters!

I have tried slashes the other way in various combination.  I've tried not including the [server_name] in the user name.  I've tried different drive letters.  The NAS is a Thecus N4100PRO and it's running a form of Linux.


Update:  Never mind.  Even though prompts in the setting page suggest using the server name, the scope seems to have a problem with name resolution.  I tried the IP address of the server and it worked.  Thanks for helping out.

Update #2:

So this is what worked for me:

Drive letter: I:
Directory: //[server_IP]/[share_name]
User: [server_name]/[user_name]
Password: [password]

When is saves something, the scope creates a directory called "SIGLENT" on the specified share and stores files there.

Just an opinion, but if Siglent want to considered a top tier brand, they will have to up their game on documentation.  Any time a feature is added or amended they should create and publish an addendum to the documentation and/or update the documentation.

Also in the release note for 1.5.2R1 - "Supported time zone setting"

Such approach would end up in top tier brand prices too. Not what I want.   

[BillyO]

Not really.  Not in this day and age.  Modern publication and content management tools would make it a snap and they have been around for a couple of decades now so there is a lot of expertise surrounding them and proper use practices.

[Martin72]

I could go and tell it our sales department, maybe our customers would get the documentations for free then instead of paying extra.

BTW, in lecroy manual you won´t find further explanations to the described functions.

[BillyO]

I guess everyone is okay with poor documentation?

Programers manual (for SCPI) is reference manual. And Siglent manual is not less detailed than Keysight one. On my 3000T I also use SCPI manual for details..

In perfect world we would still have documentation like old Hp had. But today they don't have it either..

[Martin72]

My guess is, the manufacturers assume that you already know for what the functions are good for.
It´s not their task to educate you, this must be happen before.

[mwb1100]

I'm sure that plenty of people here remember the days when you'd get schematics and possibly even source code for the software (remember that IBM published the BIOS source for the PC).

Sometimes you can still get that info, but almost never in the manual anymore.  You've gotta dig it out of some support site or github repository - if it's made available at all.

I feel like I need a custom rant emoji.

[BillyO]

Programers manual (for SCPI) is reference manual.

Not sure about that.  There are many things about the scope not included in the programmers manual.

Just how are you to be pre-educated on a new (undocumented) feature to a scope?
