Siglent SDS2000X Plus

[Martin72]

Further things done...

Marked and drilled holes and paying attention, not to leave any metal chips over.
Also I´ve done the mounting with polyester screws/nuts only.
I think, it will be finished today.
To be continued..

[Martin72]

Finally it´s done...

No need to cut off the connector from the original fan when you got the preciva crimp set...

Reassembling the unit and turning it on - It works and.....silence is golden..

This solution is probably one of the best, but my warranty is now lost.

Other no warranty lost solution:

-Make your own connection cable as described before, so you could change back to the original fan without leaving any traces..
-Warm up the warranty-sign before open the case...
-Take the LNA (Deichgrafs post) instead of adding a pcb to reduce fan speed...

Hi Martin,

good work and if I had a clue about the preciva cimp set ...

So you used also a NTC temperature probe to control fan RPM depending on how hot it is in the box?

Regards

[Martin72]

Hi Deichgraf,

Thankyou and yes, the ntc is part of the speed controlling, according to the DIP switches.
Me I thought, I´ve switched it to 40°C but it seems the fan is running at full speed from the beginning, so I must check it again - Although and even at this speed the noctua fan is remarkable quiter than the original.

if I had a clue about the preciva cimp set

Last year I´ve bought this complete set on https://www.amazon.de/Crimpzange-Dupont-Stecker-Steckverbinder-Crimpkontakten/dp/B07QX51F3B/ref=sr_1_4?__mk_de_DE=%C3%85M%C3%85%C5%BD%C3%95%C3%91&keywords=preciva+crimpzange+set&qid=1636314038&sr=8-4]Amazon
It works well, didn´t regret it so far.

so I must check it again

I´ve bought the fan controller on amazon and as "always", there´s no manual avaible..

But thank god, someone in the world wide web checked this controller before:

Ah, now everything seems clearer....

After done the settings you can´t hear a damn thing, very nice...

Does anyone have a link to the ADS file to enable telnet for the SDS2000X+ on the latest firmware? I can't seem to find it anywhere.

Last I checked there was no need to go poking into the OS on these when the online scripts work just fine.

For normal purposes, you are correct. I'm just looking to do a little investigative research.

10/21/2021 - 1.3.9R6 - Wrong FFT frequency when memory depth > 10 Mpts

FIXED! Yea!

Hello

Do you know what are the differences between the different hardware version ?
I noticed at least two versions : 02-00 and 02-04
If it hasn't been discussed yet, I'm curious to know what subject these differences play on ?

There is third pin place on scope board and I think there was something for fan speed when exploring the conf files, maybe it works only with SDS5000 though. Might be worth going over.

[oz2cpu]

them SP2035 probes !!
it has been up quite a few times before, BUT now I wanted to solve it, once and for all,
it is possible to take apart the tip, and the metal part out, now press a little bit , see red arrow, now the metal is in contact with the scope tip.
I also added glue to make it more easy to use.
The BNC end : the 6 gnd blades are normally supposed to be a bit springy, they are not like that at all,
so the connector body is way to loose and with unstable gnd contact with the scope, carefully bend all 6 blades out
only as little as it is barely visible you did it, now feel how much better the connector mate with scope,
and note your measurements are nice and stable.

hello everyone... i just got my SDS2074X Plus, base on old post i make it to 500MhZ ..... only the SDS-2000-FG cant use... anyone can tell me how to active it? many many thx.

Search works just fine:

[dannytt]

i have tried it many times... but all not working...  only the FG part not work other all fine

[Bad_Driver]

Very very simple. You have to use the FG at least one time in the test/free mode before you can enter
the serial number. I spend a nice afternoon with increasing frustration since it was the first license
I tried to enter and I thought the whole improvement process wont‘t work with my device.

Hi Performa01!
https://www.eevblog.com/forum/testgear/siglent-sds2000x-plus-coming/msg3782555/#msg3782555
I am very happy with this topic! 😊
I would like to use it for sound frequency measurement (FFT).
If fed with a lower distortion 1kHz generator, would much smaller distortion values be measurable?
For example:
-80dBv THD 0.01%
-90dBv THD 0.00316%
-100dBv THD 0.001% 😊
Regards Garga

[Performa01]

Hi Garga,

sorry, but you cannot use an 8 bit system to measure very low distortion levels.

With appropriate dither or an auxiliary signal, the dynamic range could be stretched up to some 70 dB, that means 0.03% theoretically. But it's tricky.

For distortion measurements, I use a Picotech 4262 DSO, as this provides 96 dB dynamic range already without any tricks.

[dannytt]

o thx very very much. thx everyone which helped me...

[piramida]

To measure distortion, you can use a notch filter to "cut" the first harmonic.

For distortion measurements, I use a Picotech 4262 DSO, as this provides 96 dB dynamic range already without any tricks.

This scope is confused by a bandwidth of only 5 MHz.
A 5000 series picoscope with switchable vertical resolution ADC is not suitable for this purpose?

[Martin72]

This scope is confused by a bandwidth of only 5 MHz.

Should be more than enough when measuring distortions in music-range up to 20khz.
But we´re going out of topic here..

[piramida]

Should be more than enough when measuring distortions in music-range up to 20khz.

It turns out that one device is needed to measure distortion, and to see, for example, the self-excitation of an electronic circuit at tens of megahertz, another device is needed ...
