Siglent SDS2000X Plus

[Bad_Driver]

performa01, thank you for answering this way.

You were right, the differences came from different dc offsets between the channels.
I run a self-calibration after the firmware update and  the differences between rms and stdv reeadings vanished.
So the screenshot is not needed anymore.

I used the SDS2354x to get an exact noise level of 0dBm with 40 MHz bandwidth from an SDG6054X.

To set the exact level of  223.6 mV the Measure -> Tools -> Trend -> Trent-Stdv function  of the scope
is very helpful to get a 'quiet' reading.

I adjusted the SDG to for a reading of 223.5 mV average(stdv)  from the scope, the SDG showed 256.8 mV output at 50 Ohm then.


I verified the reading of the scope with an SSA3032X-R which should  have showed a level in dBm/Hz which is 10 * log(40E6) dB lower
at -76.02 dBm/Hz.

The analyzer readout was -75.85 dBm/Hz (f=10MHz,Zero Span,BW RBW=1kHz,VBW=10Hz. AVG=200) which  showes a very satisfying
accuracy of Siglent measurement devices.
With a noise-bandwith of 42 MHz the reading at the SSA was -76.0dBm/Hz!

The SDS2000Xplus scopes have more bandwith and therefore a better crest-factor than the old HP 3400A or 3400B rf-millivoltmeters.
Such a scope is a remunerative investment for hobbyists in many repects.

Can you post a similiar measurement with your SDS2000X-HD?

Very cool! I instantly repeated your measurements! No adjustments done, (SDG settings: 223.6 mV (0 dBm), Noise, 40 MHz BW)
See screenshot attached. both devices connected in parallel, 50 Ohms termination at the end with the SSA-input.
Generator is SDG2122X, same settings as yours. Well done!

Does the Siglent SDS2000X Plus or SDS2000X HD has the "All measurement" function in the Measurement Menu that can display all the items of the current measurement source?

No, not in the same way as SDS1104X-E.
Sorry all sold out of SDS2000X Plus however AFAIK the measurement structure is very similar to SDS6000A so a couple of screenshots as examples.
Simple Measure is the closest to All Measure in the X-E however in Advanced we can have a list of up to 12 all showing Value, Mean, Min, Max and Stdev plus an assortment of control parameters for the measurements too, like Gating etc.

Hopefully someone can 100% confirm X Plus and HD has the same Measurement feature set.

[Performa01]

Yes, I forgot how to handle the "Simple" measurements...

There is no "All measurements" button anywhere, however we can configure as many simple measurements (without the option to display statistics and restricted to just one channel) as we like.

See attached screenshot for the SDS2000X HD, but it's exactly the same on the SDS2000X Plus. I have simply activated all available measurements for Channel 4 - of course the channel delay measurements aren't available for a single channel. But the measurements set will stay put, so we can activate it anytime and we can change the associated channel without having to define that simple measurement set again.

And for this, source can be selected channel main window, zoomed window, math result or saved reference and measurements can also be gated. Least in SDS2504X HD and afaik same in X Plus..

Why exactly do you need such functionality ? 

[tubularnut]

I don’t at present, it’s a historical thing when I was asked for internal information by another prominent member, just pointing it out for anybody else

Thanks for your help.

Would you show how to enable or configure the simple measurements that can display over 50 measurements in screen?

[tautech]

Would you show how to configure the simple measurements?

I can describe it very simply, in Simple click Type and select the measurement types you wish to add.
Scroll back up to the first SDS6000A screenshot I posted where there are only a few measurement types displayed where you can just add more.

[Performa01]

Activate the Measure Menu, select "Simple" mode.

It might be best to start with an empty set of measurements, hence press "Clear". See first screenshot.

SDS2354X Plus_Measure_Simple_Clear

Now press "Type", activate the appropriate tabs (Vertical, Horizontal, Miscellaneous) and select or deselect the desired measurement items. The items will appear in the measurement set in the order they've been selected. If you deselect an item, then other as with the advanced measurements, the item will disappear from the set and the gap is closed. When you select it again sometimes later, it will be added at the end of the set. So you have to be careful if you are interested in a certain order and grouping of the items. See also the second screenshot.

SDS2354X Plus_Measure_Simple_Type

Finally you have a set of measurements. I've defined one that contains what I think to be the most useful ones as an example, see 3rd screenshot:

Hi,
I have a Siglent SDS235X Plus with the latest firmware 1.5.2R1. Hardware version is 02-04. Since the firmware update this afternoon I have no network connection. DHCP does not work. I can enter a static network address, including subnet mask and gateway. The network icon shows a connection, but I do not see the SDS in the network. Before the firmware update I had a perfect network connection. Does anybody have a similar problem?
THX, Pascal

[kladit]

No problems here, same FW-update.
The only difference is: I do not use dhcp but an nameserver for my local net and static ip-adresses.
A friend made the same FW-update and has sent me some screenshots today, so he has had
no problems as well. But I do not know if he is using dhcp.

[trp806mo]

nope

[mathstudi]

THX for the quick reply. This is another one of those days where an error pops up at the dumbest moment. Yesterday evening the Ethernet switch was still working. Today after the update, the switch had to break at this very moment  . After replacing the switch, everything works fine again. Weekend saved  . THX, Pascal

Looked at work  on the X plus, yepp it´s the same as at home on my HD.

I thought this feature was used for disaster recovery, where you provide files for a magic usb stick?

Disaster, from what ?
You don't need Telnet to play with these things as we have an SCPI command panel in the webserver.
Any command not in the command set gets ignored whereas all the magic unpublished ones work just fine. 
It's all here in the forum for anyone to find.

I'm having the same issue. I just see a timezone dropdown box with nothing in it and I can't select or change anything.

You are the disaster recovery expert, but perhaps when you do this sort of thing?

My 1-week old SDS2104X Plus no longer works. It hangs while booting (see attached picture). Any idea how to troubleshoot it, before calling Siglent on Monday?

Sure, flick us a PM with your email...... ve have the tools !

Not talking about telnet btw, but the fact that running a script during boot is now disabled.

Is it, not looked however it won't be long until certain prominent members here find other penetration methods but I know not what for. 
All the Siglent Service centers have recovery packages and there's absolutely no need go looking into the OS as the Python script negates any need to.

Again, not talking about looking into the OS, telnet or not. I'm just asking if Siglent broke their own recovery tools by removing support for running scripts during startup. Have you tried the recovery tools after flashing the newest firmware?

I'm having the same issue. I just see a timezone dropdown box with nothing in it and I can't select or change anything.

I see references to "/usr/share/zoneinfo/" in the firmware, which on a regular Linux system contains the timezone files.
But I can't see any timezone files shipped with the new firmware. So perhaps it's already included on new devices, but not older ones?

Update: since I haven't updated yet, I had a look around with telnet to see if I could find the files it's looking for:

Code: [Select]

/ # ls /usr/bin/siglent/usr/localtime
ls: /usr/bin/siglent/usr/localtime: No such file or directory

/ # ls /usr/share/zoneinfo/
ls: /usr/share/zoneinfo/: No such file or directory

Would be interesting to know if "/usr/share/zoneinfo/" exists on the latest generation of devices.

Them USB so shouldn't be a problem.

The script support they disabled runs from USB, so could still be a problem

Unlikely they set out to break their own tools.
