Siglent SHS800/1000X model Handheld Scopemeters

I was looking around to see if Siglent is selling them refurbished at all?

I was looking around to see if Siglent is selling them refurbished at all?

Not that I'm aware of and there's none available on the US website Clearance listing.

You might like to see if ePay or your fav online shop have any of the previous SHS800 or 1000 models available 2nd hand:

so, why not two handheld scopes? 

I looked around for a deal on the 810x, not finding one, for grins, I ordered one of the zoyi zt-703s models to see if I liked the format.  And I do, so after playing with the 703s for a few hours, (amazingly accurate meter for the money) I ordered the 810x a few minutes ago.  I didn't read to see if it has any of the bode plot functions like on the 1104x, that would be nice.  I have the Siglent standalone signal generator that I bought around the time as the 1104x.  I had coded an application that drove other signal generators based on code that another person authored, but the bode plot on the 1104x with the Siglent generator didn't require a PC like my code did.

Anyway, looking forward to more convenience with the 810x, don't know if I'll upgrade it or not to an 820x.

thanks

Given the 810x and others in that line have the correct USB ports needed to control a signal generator like done on the 1104 x model for bode plotting, it would be great if they added that function to this model as well. Mine arrives tomorrow, but I was looking at some videos, and I was shocked to see how large it is.

Messing around with the UART decoding function and I found that decode + zoom worked better for my purposes than decode + table (only shows max 8 values and gets in the way).  I can see more context of what is going on, an read the messages flying by.  Used normal trigger.  Of course still limited, if I zoom out more than shown, the zoomed-in signal will be too broad and the ASCII characters will no longer show (do not fit in their placeholders).  However, I can stop and scroll left and right, which is pretty handy.  Signal was a wifi router booting up, got a X1 probe on the serial console output and ground.

Christmas is here early.  Have not tried yet. Number 2 sounds interesting.

SHS800X_Firmware_V1.1.23 (Release Date 04.22.25 ) - https://siglentna.com/service-and-support/firmware-software/handheld-oscilloscopes/#shs800x-series

4/21/2025 1.1.23
1. Support Polish language.
2. Support screen inversion.
3. Recompile the FPGA version, solve the black screen issue of the
SHS1000X display

I just updated my SHS1000X to the newest firmware!

The option to invert the display can be found under [Display/Persist] > Page 3/3 > Screen Normal / Screen Invert.

In general I like the new color scheme, but there's one major issue: The waveform intensity and anti-aliasing are still for a white background. This makes waveforms look quite ugly in dark mode and renders intensity grading a bit useless. If you turn down the intensity, the waveform becomes bright white instead of very dim. So, there's still work to do to make it useful. For now, I'm back to the white background.

See attached screenshots for an impression.

Thanks for this. I was finding the same thing about the aliasing of the waveform. It's also annoying that I find I have to adjust the 'Transparance' value from 80% to 20% to make the values readable in the cursor position boxes etc. They should have inverted the way this adjustment works so that it wasn't necessary to change it when inverting the screen display.

Wow, that's pretty "ugly" and not usable.  I guess they delivered on their promise "Support screen inversion".  Never promised a proper dark theme, which is what we want.  It is not like they don't have dark themes that work fine on bench oscilloscopes.  Definitely hoping they fix it in a future firmware update as I would much prefer a dark theme.  Going to install update but I don't think touching that inverted screen with a ten foot pole (except maybe out of curiosity).

The meter display looks better with the new inverted screen:
" alt="" class="bbc_img" />
" alt="" class="bbc_img" />

Unfortunately, you have to flip back to 'scope' mode in order to change the screen over to inverted.

This is not aliasing but waveform and system noise.
Engaging a little Averaging clears the waveform noise.

Unfortunately, you have to flip back to 'scope' mode in order to change the screen over to inverted.

IMO this is a bug as any user setting should be returned at next boot.
I have reported this to Siglent.

What I didn't find time to check was setting if a User Default was set to Inverted display whether or not it would be returned at next boot.
If that works it could be a temporary workaround while we wait for a new firmware.


All in all I like the new inverted display option which makes these units much nicer to use at the bench rather than the bright background that's better suited to low light conditions a technician might find on job sites.

It's taken around 1.5 years, but it's good to finally see some progress on the screen theme... The waveform "aliasing" in Inverted mode is a bit unusual (and annoying), but it can be slightly improved with some tweaking of the settings, to some degree. It seems it is not doing a pure "inversion".

I think the reason the waveform shows this "aliasing" is due to them trying to keep the waveform base color as BLUE, rather than just letting it fully invert all items on screen, which would naturally change this waveform to yellow... If it were doing a true inversion, it would look more like my manually edited image in "Reply #80 on: September 21, 2023, 01:23:33 pm" in this thread. Also attached here.

Very frustratingly, the Inverted mode doesn't stick after a power cycle, and it doesn't stick to saved configs or to the "Default" key... I can use the inverted mode for most things I need to do, but I really hope it gets some more updates to improve it because it is not implemented to the same standard as my other Siglent products with dark themes or inversion options.

@mahi,

Attached is your normal (not inverted) screen capture from a few posts back, that I have inverted with an image editor. I think that if Siglent did this to the trace at least, it would be a much better result than what we have a the moment, IMO.

Scrub aliasing from your mind totally, inverted display in these is equivalent to a normal benchtop display and the trace fuzz seen is NORMAL system acquisition noise.

Don't believe me ?
Engage Averaging and noise disappears.....

Remember, this is an 8bit device so traces will never be fine/thin or clean like a 12bit DSO.

Unlike benchtop units, when Average is engaged there is zero OSD that it is and I have asked Siglent to add this and keep inverted display at next boot when Invert is selected.
They have acknowledged and sent these recommendations to R&D to be developed.

No, that is not what I am saying. "aliasing" isn't the issue here, I agree with you... I put it in " " because it's what it was being referred to in this thread. I believe it is a color grading/pallet inversion choice they have made, that would be solved IF they did a complete inversion, and were not trying to keep the trace color BLUE in both Normal and Inverted modes. (The "Noise" is still drawn in white, and shouldn't be). I don't believe what we are seeing has anything to do with the bit depth of the scope or anything other than a color pallet inversion choice, made in the firmware, that they have not got working well so far. 

If the "noise" (white-ish color areas surrounding the blue trace) you refereed to were also inverted, it would look more like my manually edited image (attached), and it would look like my other 8bit scopes that look fine in dark theme or inverted modes. I am happy to see the noise - but I want it to be drawn in an appropriate color (white is not good on a black background!). Maybe they simply missed this?

I don't want to run the averaging modes in my use case (audio and RF analysis), so if they do add your suggestion (which would be good regardless), I still think the original issue can solved by working on the inversion method. Or, even adding it as a 3rd option. Normal / Invert 1 (blue trace) / Invert 2 (true invert with yellow trace as per my image attached - this still includes all the noise but looks much better).

Cheers
