Why not going directly to a SDS5104X ?

Zodiac or bust, lame its china only

[jemangedeslolos]

What is Zodiac?
Their new hw platform?

[Elasia]

Yeah.. that was the project name for the SDS6000 series

Nah, it was physically too big for my desk

What is interesting is that investigating this designation mystery lead me to discover another thing that may be a breakthrough for a group of other Siglent equipments... Stay tuned!

Oaaahhh, cliffhanger….bad, really bad guy 

[0xdeadbeef]

Surely SVA/SSA related.

Surely SVA/SSA related.

Nope. Other SDS's...

Changed model to SDS2504X Plus using the sys_cfg.cfg copy method.  I made a backup to USB before replacing it.

Made some measurements:

Marconi 2024 signal generator -> SMA-SMA cable -> SDS2104X plus (hacked to SDS2504X plus) 50ohm input

10MHz 0dbm loss
100MHz 0dBm loss
200MHz 0dBm loss
500MHz 0dBm loss
550MHz -3dBm
700MHz -6dBm
900MHz -10dBm
1GHz -20dBm or greater attenuation.  Signal not reliably visible at any vertical scale

I thought that sys_cfg.cfg was just about the displayed name!?

[TK]

I think it is a binary file... just in case...

[tv84]

I thought that sys_cfg.cfg was just about the displayed name!?

And you thought well!

[snoopy]

Since the bandwidth limiting is done inside a chip is it possible to hack the 100MHz version to 500MHz ??

cheers

Yes. Look at: https://www.eevblog.com/forum/testgear/siglent-sds2000x-plus-hack/

Hi everyone,

I'm new to this Forum and for some days a new owner of that beautiful device! I own an Electric Engineering Degree for 35 y now and started
on the wrong side of the iron curtain with elctronics, (TTL, Zilog Z80, CCD sensors...)

I'm out of the E-business for 25+ years (and now in the healthcare industries) but for 10y I restarted as hobbyist elctronics.
In the beginning with Audio, now with microcontroller etc.
I looked around for month for a new Oscilloscope @ EEV, looked all the related videos @ youtube, saw Daves teardowns and at the end I considered to buy the SDS 1104X-E, later than I was more focused on the Rigol MSO5000.
Then the new Baby showed up on the market and after dealing with the WAF I orderd it by Welectron and it arrived after 2 days!!

Now to my small contribution to all followers.
After playing around with the device I started well prepared with all Information from this Forum the "improvement" process.
But unfortuneately it didn'd work for me! I double and tripple checked the Scope ID, tested all variations with upper char and lower char, tested every tool
I found in the web - nothing!  "Your data were not accepted"
To make a 5 hour long story short: At the end it is a bug in firmware. (My device arrived with 1.3.3) But I think I better don't report it....

To have this famous christmas feeling (starting with the smallest parcel) I began with "improving" the FG-function and not the bandwith.
But this is the only one you have to use once before you can enter the code!!!! 

After hours I switched to other options which all worked and found that little bug! So never start with improving the FG-option without using it before!
For newbies as me it is also worth mentioning that you have to do the bandwith improvement in steps from 100->200->350->500 and to avoid the others or
shortcuts (i.e. to try to go from 100->500 in one step)

Attached a measurment I have done over night to check the timebase with an 1pps GPS pulse. The second measurement is a Feeltec FY6900 Generator.
Both not that bad!!


My device reports itself as SDS2504.

[0xdeadbeef]

It doesn't really matter for your measurement and just for the record: using channel 1 and 2 or 3 and 4 at the same time results in the scope not being able to interleave its AD converters and memory which effectively halves the sampling rate and memory. So when using only two channels on a (typical interleaving) 4ch scope, it's good practice to use only e.g. channel 1 and 3.

Not true!  You can jump from 100 to 500 and back to 100 with no problems. The scope has no way to know if you were at 100 or 200, etc...

[DL2XY]

While testing my alternative digital probe adapter design i have found some quirks with Measure Statistics:

If all analog inputs are disabled the statistics of digital inputs are not updated, only the actual values are.



Someone who can confirm?
 

[Bad_Driver]

Hi tv84

I'm pretty sure that you are right. But how to do that?
In the options menu you only find at first the choice to upgrade to BW2 (100->200) after activating from BW3 (200->350) and than BW5 (350->500)
I didn'd try to enter the "last" improvement key at first, would that be possible and is this the way back to 100 MHz?
Thanks for your advice!

Another dumb question:
Can someone plz explain how the device performs 10 bit resolution. In my understanding there is no 10 bit ADC inside?

Limited to ~ 100 MHz.
Check the first couple of pages in this thread.

With the SCPI MCBD command. Look around.

USBTMC is command and control via USB, i'd say its for identifing if this model has support or not and further sets up the module with the ID codes


But whats up with... neuter? lol, i almost dont want to know

Nice Find

I am getting strong feelings of envy by not having a SDS2000X Plus - maybe time to join - TEA therapy - or simply get the damm device to enjoy the journey of discovery with you guy's
