The probes feel a little cheap and fragile
Hello,
I have not yet removed the protective cover from the screen but it looks like
that the lcd is protected with a glass. Very nice.
The probes feel a little cheap and fragile and this is probably because they are...
Having said that, I did not have any problems with them all day today. Maybe they will
show their quality in the Mhz range. They were calibrated very easily.
Other negative is that when you turn the vertical and horizontal dials, the indicator lines are lagging.
They are not instant and the waveform takes some time to be displayed again. Definitely something
that needs to be fixed.
Bellow you can see a very nice sinewave with the probes not connected to anything...
50Hz, so its picking the mains frequency somehow.
Do you know how can I prevent this?
When I moved it to a different room it stopped.
Now if I switch on the main light of the room I get the following signal.
Its not like that actually, because if I turn on 5sec persistence I can see two different 50hz signals.
I can also see spikes when I turn on & off some lights in the room.
Thank you.
George.
There is limit of processing capacity. With it need live. It is hard to make this faster. Of course if change priority of processes but then perhaps some other thing suffer. It is compromise.

I don't think the delay between changing the time base or vertical setting and the time when the trace re-appears is a problem with processing capacity. It's much more likely that this is just a firmware bug. The scope is quite fast and this problem only occurs sometimes (at least on my CNL scope). I'm pretty sure Siglent can fix it easily in one of their next firmware releases - if they are aware of the problem, that is.
Aside from the problems you already mentioned, I also found some idiocracy in their logic for the RUN/STOP and SINGLE button. If you press RUN/STOP the scope stops its acquisition cycle as expected. But if you press RUN/STOP again it only does a single sweep. You have to actually press SINGLE to get the scope going again.
Wuerstchenhund it is a bit strange the way they are using the Single button.
That confused me in the beginning.
Can you suggest which Testec probes will be good for this scope?
Another 'fault' in the UI is that when you press the Measurement button, it displays on the right side 5 user selected measurements which is very handy, but labels and numbers all have the
same white colour!
They also should have used double lines for each measurement.
Easier to see and space for 7 handy measurements.
In addition, I also don't like that, when you switch off the menu by pressing MENU ON/OFF, the selected menu section (i.e. AQUISITION) remains illuminated even if the manu is switched off. The button should only be illuminated when the related menu is active, i.e. visible.
Are you sure?
Perhaps after few days you find reason why...
(you turn off menu only from display area but... )
Actually this might be handy, because if you press the 5 vertical display buttons
you would already know their function by looking at which option is lit.
If only meaning is that led is on if menu is open visible on the screen and off if menu is not visible on the screen what information this led is for - nothing. Situation can know if just look display. So.. it can think, do it include some information. If only informatoin is show that menu is on or off on the TFT this information can get if look TFT and this led can take off and save manufacture costs some tenth of jiao.
Menu can be displayed on the screen or it can be hide, also including this that meny can disappear from display automatically. You can shut off menu display automatically or manually but still this menu is active (but not on the screen area). Also if display go screen save, still you can see what menu there is active and push button and do "blindly" setting in this active menu. This led is not there without reason. It give information, even if selected menu is not displayed.

I'm not sure I understand what you're trying to say. The LED in the buttons is there to indicate which section of the menu is active. If it is on then it means the displayed menu belongs to AQUISITION or whatever has been selected, if it is off then it means no menu area is currently active. If you switch off the menu via MENU ON/OFF then the menu is no longer active, hence the LED in the button should occult.
This is standard logic in user interface design for years.QuoteMenu can be displayed on the screen or it can be hide, also including this that meny can disappear from display automatically.

Are you saying that the soft keys remain active even if you switch off the menu (I assume they are not, although I haven't tried it yet)? If so then this is a design flaw, contradicting well researched and established user interface design conventions.
I'm also surprised you really suggest that being able (let's assume the soft keys remain active when the menu is off) that pressing softkey buttons blindly is actually a good thing, as it's pretty stupi to manipulate a control if you're not sure what it really does (remember that many menu areas have multiple layers). Doing that is not a good idea, it simply is sloppy behavior which will only lead to errors.
Any device that allows what you're suggesting is simply badly designed.

It works just perfect.
If you want continue normal use you turn off single mode... what need do... ok...push agen Single button and now light is off and single mode is off. Scope run now normally and run/stop is green until you push it to stop or until you go agen for single mode.
Push single...light on... push it agen...light off.
You can try, select cursors. Select example cursor A for adjust with adjust knob. You see there is now led on top of this knob. Then you want turn OFF displayed OR there is timer what turn menu bar off. But, in bacround it is still active and turn adjust know still you can move selected cursor. If hit any of menu bar buttons, menu bar coma agen to displau and it ius just this menu bar what is active n bacround. I personally feel it is nice feature more than bug. Also same for display menu.
Activate it. Turn menubar timer to 2s. Then select example brightness or in other some menu some other adjustment. But fast menubar disappear, still your control is active.
Of course if this is car, train, aeroplane... it need really be different for safety reasons but here..in oscilloscope, nothing bad happend if you push any these menu bar buttons... only it may step to next available setting behind this button in order and if there is three possible setting... example in trgger it just jog up, down both edge every time you push it... and menu bar pop up on screen also for tell what happend...(until it disappear how you have selected) ... if it was wrong button just push next time it or more until setting is agen what need and then push right button. After people is familiar with it... I think it more positive than negative feature. It may make oscilloscope using very fast. Ok, there is opposite thinking... in some kind of just very opposite is Owon. Every time you push this, and this and this and that and what ever you do all agen and agen... but you always know. But in long run... it start sometimes feel very "stupid" or frustrating.
Wuerstchenhund, you are right. Exactly! I totally agree with all the above!
The thing is that this is just bad UI design. It's no problem having a 'short cut' for certain functionalities but it's not ok having soft keys remaining active without the corresponding labelling via the menu. A solution would be to replace the menu items with symbols if the menu is switched off (i.e. a small bar containing symbols for currently available soft key functions which could take very little space). Then the MENU ON/OFF key behaviour could be modified to toggle between full menu - symbol menu - off.
This is just an example. There are many ways to make the UI better. But ignoring common and well established UI conventions is not earning them any award.

I have put together two examples of how the screen with all measurements active could look like.
In the examples below, the measurements are located on the bottom of the screen instead of hovering over the waveform. This reduces the vertical waveform area slightly but in my opinion is better than having the measurement data block covering a large part of the waveform.
I have also moved the frequency counter display outside the waveform area (there's enough space for it anyways), and the trigger level readout is now located close to the trigger indicator on the top. I also added a sampling rate indication, which is what I miss a lot on the screen.
The difference is in the location of the lower status bar.
As comparison, the third image shows the current design.
