Siglent SDS2000X HD, missing Features and Bugs

[PartialDischarge]

Curious if anybody else has noticed this or if it may just be a bad power supply?

Nope mine is completely silent

[Martin72]

Hi,

Yes in Standby you can hear the supply - How loud depends on your own sensivity.
Possible solutions were to use a load resistor at the cost of low standby power or to glue the "singing" components inside.
Or, best, totally powering off.

Glad to know I'm not crazy!

It sounds like a mosquito flying in your ear; intolerable. I used my phone to see where the hum was in the spectrum, attached for curiosity sake.

I can't imagine opening a brand new scope (brand new demo unit mind you!) and adding a load resistor to the power supply to fix something that shouldn't even be there in the first place. It would be an option if I had actually purchased the unit and was a few months into it's use before it showed up.

Mine has a high pitched sound when in standby, it drives me crazy my lab is fairly quiet.
Does the scope you have sound like mine? I've got an audio clip in this video towards the end. https://youtu.be/rvn4mzTLlnA

The whine during stand-by, that's it! Mine also does the same pitch "shoot into space" when pulling the plug; no point in making a recording or video myself since your video does a perfect job at pointing it out. I wouldn't be able to have the thing sit around plugged in for the same reasons, my office/lab space is rather quiet and it'd drive me nuts.

I suspect it's either some audible range pulse-skipping frequency in low power mode, some mechanical vibration in an XMFR in the PSU, or maybe even instability at low power. I doubt it's fixable in software unless perhaps a sub-system is left on during standby to add enough load to have the whine exit the audible range. Just my thoughts.

[Martin72]

It´s a supply from meanwell:

EPS120-12
I think the coil from the output could be the "singer" (Pic)...
My solution is on the other pic.

[Frankupthehall]

What happens if you encase the coil in nail polish (if you have some handy)? That or varnish, something to stop the wires from moving.

I can appreciate the practicality of simply turning the bar off. But I'm of the opinion that a scope at this level should at least not whine about being off once and a while. 

[Martin72]

Mostly the psus of other scopes are hiding under the metal-case, so if they "sing" (not unsual behaviour under no load condition) you probably won´t hear it.
This one here is outside this case mounted.
Got the advantage, it couldn´t stray directly into the circuits, disadvantage sensitive people could hear something.
Sure it´s not nice, maybe siglent could do an exchange of "noisy" psus or let the warranty remain if it will be fixed by customer himself.

Edit see pics

Bug, or massive oversight.

Digital channels have sluggish response and low update rate, with waveform update rate of 16 wfm/s (100ns/div, 2kpts, 8 channel) observed by a couple of owners.

Here a wish, siglent can fulfill when they´re having nothing else to do or lost a bet or got a apprentice who needs a task...
Decoder-feature:
Decoding of IR-transmitting codes, Like RC-5 and others for checking functionality of remote controls.
This would be absolute unique in the scope world, no one have this feature...
So maybe someday in the future, when everything was done, before EOL a last present...

I have a problem with the time, more precisely the time zone.
if I set it to UTC, the time is correct and stays correct
if I set it to europe/paris as it should be, then set the time, it is ok if I restart the time is 1 hour too much
couldn't you set it with an ntp server ? it would be automatic.
I have the last actual firmware 1.2.1.1

Hi,

Hi,

See:
https://www.eevblog.com/forum/testgear/siglent-sds2000x-hd-missing-features-and-bugs/msg4458874/#msg4458874

noted, but I still consider this as a bug that can be fixed in a future firmware...

[Martin72]

Therefore I´ve wrote in the linked post:

Gentlemen, we have a bug....

 

[kripton2035]

one feature I would like, is to have a way to measure calculated values.
like the formula editor for maths channels, but for advanced measurements.
measure built-in things, like width and duty cycle, and for example display also some calculated value with these two.

[kripton2035]

something I don't understand too is why the AWG is only a 25MHz one, and the AWG in the SDS plus is a 50MHz one
also this AWG doesn't have any modulation capabilities ? only simple straight frequency signal ?
it is then only usefull for making bode plots ?

Add support for the SDS2000X HD to Sigrok.

https://sigrok.org/wiki/Protocol_decoders
https://sigrok.org/wiki/PulseView

You can do this with any of the existing supported scopes.

Now, finding a way to integrate sigrok & PulseView into their scopes natively would be truly mind-blowing.

[kripton2035]

the sds2000(plus) is already detected by sigrok pulseview. so the HD should also be in. will test in a few hours.


edit: tried to connect to the 2000hd with pulseview using lan connexion (my computer is too far from the scope to use usb)
and I did not succeed to connect to the scope... using port 5025. any hint ?


edit2: after playing with pulseview trying to connect, just found the scope completely stuck. no button no touch screen. had to force restart.

[kripton2035]

if you hit the default button, it resets everything, but does not detect the 10x probes (the ones that are shipped with the scope)
you must unplug and replug the probe and it detects the 10x again.

You might try the SCPI commands listed here:

@tautech does the 2000HD have a front-panel lockout when using SCPI?

the web interface of the scope was stuck too. so not possible to send a scpi command. no other option than force restart...

Hmmm, just went looking for HD drivers and there isn't any.

Sinisa, can you check this stuff out as we still don't have an HD ?
