Siglent SDS2000X HD, missing Features and Bugs

@ Tautech

The probes are set to x1 after you press the default button and they are recognized as x10 probes after unplugging.

Yup. The bug has been reported for every model that can sense probes. Unplug and replug them in, or manually set them to x10. It's the only thing that really annoys me with the scope.

An other enhancement I would like to see is the ability to set the horizontal offset at a fixed position.

Let's say you set the offset to -80 µs with 20 µs /div. When the time base is adjusted to 10 µs/div, the offset should should be adjusted to -40 µs. As it is now, the offset is constant and the trigger position is off screen. That's not practical and I have to adjust the offset all the time.

In Utility-> System-> Reference position you can choose Horizontal Ref to be "Delay" or "Position".
When set to Position timeframe will compress/expand around set Position.
I believe you are now in Delay mode.

Thank you very much. It's even in the manual...  But not under chapter 8.3 where they discuss the horizontal controls but under 32.2.6 "32.2.6 Reference Position Setting.

[Martin72]

The manual needs to be updated anyway.

There is a temporary solution that can be used. If you frequently use the 10X probe, you can use the "To Default Key" function.
1. Set the probes to 10X
2. Click on Save/Recall
3. Select Save mode
4. Set the type to To Default Key
5. Set Default Type to Current
6. Click on Save

After completing the above settings, clicking the Default button will load the 10X configuration.

[KungFuJosh]

Yeah, that's what I did. It's annoying though. It should be fixed properly. The coax cables currently connected aren't 10X.

New bug or some kind of anomaly.  I noticed a displayed dc offset that should not have been so I performed self calibration and all channels then showed offset (see screen grab with all 4 set to GND).  Then, I tried measuring a DC voltage and the error was enormous (300% or more).  Since I have had issues with this scope before, I tried the usual and disconnected it from the ac line and then repowered and did another self calibration.  All OK now

This is a fairly serious problem.  Have any of you seen anything like this?

[Martin72]

Hi,
I've experienced something similar before, but I can't find the post(will search for it).
I also had this problem:
https://www.eevblog.com/forum/testgear/siglent-sds2000x-hd-missing-features-and-bugs/msg4601140/#msg4601140
I was able to get both back in order with self-calibration.
And you could also set something on the scope regarding self-calibration, as I said, I'll have to look again where that was.

[Grandchuck]

Thanks Martin.
This particular problem is unsettling.  If I had not noticed the offset, I could have made who knows how many useless/misleading measurements .

Could you please reset the scope to default settings?
Just to make sure all internal variables are properly initialized.

After FW upgrade it is not bad idea to perform reset to default.

I did reset to default.  If it happens again, I will reset  to default again and will report back here.  Thanks

Thanks for the answer.
Yes, keep an eye on it and if it misbehaves again, report.

Feature Request:

Allow Ch3/Ch4 and Math channel as source for X/Y mode.

I recently ideated about the possibility to measure B-H curves with a scope:

Say you have to characterize a ferrite core, I think the gist of it would look something like: Wind two winding, primary for magnetizing the core, secondary winding for sensing.

- AWG drives primary, an amplifier is probably needed to get reasonable current into the primary to drive it into saturation.
- Measure current into primary + have user input number of pri turns and you get field strength (H), roughly.
- Measure and integrate secondary voltage + have user input number of sec turns and you get flux density (B), roughly.
- Plot in XY and you should have a BH curve.
- Stuff like saturation flux density, coercive force, remanence, hysteresis losses etc. can be calculated with maths.
- Some kind of offset/servo is probably needed to keep the secondary voltage integration in check.
- AWG allows measurement of B-H curves across different frequencies.

I wanted to give it a try with the 2000X HD, but XY mode only support Ch1 and Ch2 as source, but not other physical channels nor math channels 

I really don't want to build an actual integrator circuit to plot B-H curves, when the scope hardware and software is more than capable to do it itself! 

I double it!

Just received my SDS2104X HD and this is my second disappointment after realizing that built in AWG is licensed...

Any other manufacturers supports this?

[kripton2035]

if you bought it from some european seller like batronix, you get a bundle with the scope, and the frequency generator is in and almost all the decoders too ...

Hello,

no, you have to buy the Siglent SDS2XHD-BND separately.

[kripton2035]

my mistake, but at that price it's a steal why not buy it with the scope ?

[Martin72]

That's a good question, there have been people here who have bought the scope, ignored the bundle and then asked for a hack for the options...
I've been "advertising" the bundle for weeks, even though I don't have any of it (I don't even have the scope anymore).
Because I was electrified by how cheap it is - I paid more for the logic probes alone than for the bundle INCL. the probes.

Feature request:

User defined math for measurements (the numbers measurement, not the math traces).

For example, it would be nice to be able to multiply frequency (Hz) by 60, so that it shows RPM when I'm measuring the output of a tachometer.

All major manufacturers have inbuilt AWG separately licensed.
But also they sell bundles.

[szajsiwo]

I bought it on taobao for super-duper promo price of 11100CNY and still it was a big expense for me - not every one here earns in EUR/USD guys (USD/PLN=4 EUR/PLN=4,3)..
Bundle relatively cheap in comparison for separate licences but it is still for me a 1/4 of month salary on top of that...Just not realized that such essential functionality can be licensed. At least simple sin/square.

Anyway my post was basically about Math channel as source for X/Y mode.
