Siglent SDS2000X HD, missing Features and Bugs

[tautech]

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...

Correct, it seems to sync to some NTP server if LAN connected and not account for local DST therefore boots 1hr wrong. 

[kripton2035]

you may be correct, it's possible that just the DST is not taken into account with the timezone setting.

[Martin72]

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.

Update: Adding "FFT4", would be very useful and afaik unique to have it.
And shouldn´t be such a big problem to implement...

Generally it would be nice if siglent would realize some if not the most feature wishes if possible, depending of the model.
With the launch of the new rigol models having more and unique features would be useful to keep them in a distance....

[Martin72]

Hi,

Don´t know if this is a "bug" or a wanted feature:

Roll mode...
You can only reach it in the vertical drop down menu, not in the timebase menu where I expect to find it like other scopes it got.
Wanted feature:
Having Eres access in the channel dialogbox.

[kripton2035]

is it possible to use the internal AWG to make bode plots ? I don't find how to do that ? seems you absolutely need an external (and siglent) AWG.
wouldn't it be a great feature to implement ?

edit: ok found it 30s after asking here ...

[kripton2035]

this is the consequence of reading the Fu... manual or experiment with the scope....
and here the manual tells nothing about it !
I just powered the scope, and found the answer within some clics...

[Martin72]

Hi,

and here the manual tells nothing about it !

Two times...In the overview(page 248):

At this time, either the SIGLENT SAG1021I arbitrary waveform generator
or one of a SIGLENT SDG series arbitrary function generators are supported.

Where the SAG is the internal generator and here, 28.2.1 (page 249):
C. Arbitrary waveform generator connection settings. Touch Interface to select the
connection type

OK, it´s not crystal clear but it´s mentioned.

[Martin72]

Gentlemen, either it´s a bug or I got a defective scope...
It also only affects the 2nd channel, not other channel.
Problem: Feeding a signal, e.g. a sinvewave with an amplitude of say 700mVpp, setting the vertical to 200mV/div., no problem at all, will be correct displayed (+/-350mV).
BUT:
If you decrease to 100mV/Div. the signal gets out of the display range as if you decrease it to much.
And now the scary thing:
Turning on ch1...everything gets fine on ch2, signal will be correct displayed inbetween +/- 350mV....
It´s only on ch2..
And it must be ch1, if you turn on ch3 or 4, it stays out of range....
I´ve been away from keyboard now, for good reasons...
In a few hours I´ll load a short vid up.
Man, this makes me scary...

 On mine with fw 1.2.11 I cannot reproduce.. Even with glass of whiskey.

No alcohol..

My deepest sympathies.
On our way out for Xmas brunch quite soon where I guess we will tuck away a few with our lifelong friends as our kids are all elsewhere this Christmas.

Have a good one everybody.

You'll need to explain me better the setup. On mine it is not happening when toggling CH1.
I will look into it in detail, one of these days.. Like Rob, family time..
Reset to defaults and try again. Try also toggling 50Ω/1MΩ on both channels.

[Martin72]

Home at last...

It´s only channel 2 affected.
Settings on scope to default, it stays.
Also when turning off/on.
When ch1 is active, you can decrease ch2 under 200mV/div and it "follows" the setting as expected.
But when ch1 is off, it "freaks out" when you setting it below 200mV/div.
It´s depending on ch1 active/not active.
Ch1 is not affected.
It´s only on ch2....
"Tomorrow" I´ll test and report it again.

Apart from this, for my comparison thread I´ve used both mathchannels at the same time, for the first time..

Scope is getting slow when both channels are active, in my case both with FFT, more slowish it gets when measurings are active.
But that was to be expected, therefore no problem.
The following caught my eye:

-In exclusive mode, both traces are visible in one grid area, as expected(changed the trace colours for better visibility).
-Wish: Having the split mode in such manner, that the two FFT traces will be displayed in different grid areas without the sources.
When you change from exclusive in split mode, in the upper grid area the two sources will displayed, in the lower the two FFT traces.
-Labeling: I´ve renamed the math traces in SDG1062X and SDG2122X, so far so good.
But the tables won´t be renamed, they still got F1 and F2 as name - Wish: Tables could be also renamed.

[Martin72]

"Tomorrow" I´ll test and report it again.

Did it before the next family round starts..

"Effect" still persists.
Regardless of the input impedance 1M or 50ohm.
And it´s getting more weird:

Feeding a signal with 100mVpp (50mVpeak)....As written, at 200mV/div. everythings OK.
100mV/div only function when ch1 is also active, if not the signal is way out of range from the display.
This is what I´ve wrote yesterday and it´s still persist.
But I test further:
It is 100mV AND 50mV/div (or 1V and 500mV when probe 10:1) and now the weird part:
At 20mV/div signal is normal displayed regardless if ch1 is active or not.
Summary:
Ch2 stand alone, 20mV/div, 50mV/div., 100mV/div, 200mV/div.
Ch2 and Ch1 active 20mV/div, 50mV/div, 100mV/div, 200mV/div.

UPDATE:

Now everything works OK....What have I done ?
Setting to defaults didn´t have an effect yesterday, also turning on/off the scope.
Today the "error" persists as I´ve written the last post here.
The last "joker" that came into my mind was to let the scope doing self calibration.
And now...no issues on ch2..Should I be happy ?
What was the explanation for this behaviour...
See again the longer video:
https://www.eevblog.com/forum/testgear/siglent-sds2000x-hd-missing-features-and-bugs/msg4600561/#msg4600561
Never got this before with all my scopes including the sds2000X+.
Why adding ch1 and then everything was OK on ch2...
Now doing a self cal and the haunting is over as it came.
I should be glad and happy now, but I´m not.
I have a suspicion that I will investigate today.
After visiting the family...

[Martin72]

I have a suspicion that I will investigate today.

Nothing, leaving the scope on for hours (warming up) doesn´t have any effect.
After self-calibration a few hours ago, it still works normally.
I mean, when you got a little bit offset on a channel you use self-cal to minimize it, but this ?!
Well, it is what it is and now it´s fine.
Hm.

Martin

[Martin72]

Maybe a bug:

FFT, tracecolour is red, when in split mode, tracecolour is pink....

Edit:

When you have a closer look to the pics in the link, there´s some pink in it, somekind of "overlay"...is it a kind of "integrated color-grading" ?

Hi all,

got my SDS2104X HD in December. Sent it back because of a minor pixel defect, and got another one one day before Christmas. I did't read each post here in detail, but I wonder if anybody already played around with the cursor functionality. When I try to select the cursor mode [Measure], under measure item there is only the item "NULL" visible, and the activated universal rotary knob only adjusts the screen intensity. Maybe I'm stupid, but that can't be right... Can anybody pls confirm this?

Drop down that Mode menu..

You will have a choice of  Manual, Track and Measure..
Measure works together with, well, Measurements.
Which means you need to enable some measurements first, and then chose which one will be connected with cursors.

Aaaaah- got it (the penny has dropped)

I figured it out - but its only working with custom measurements, and the activated universal knob is still adjusting the screen brightness

To defend myself - the manual is not really clear about this topic...

Thanks for your help!!
