Siglent SDS1104X-E: What does hardware version mean?

(1/3) > >>

Linwood:
Just got this.

It came with a sort of recent software, R8 (late 2021 I think) and I upgraded to R9, however the hardware version (shown on the status screen not the web screen below) is 01-05.

I've searched and seen all sorts of numbers including some seemingly much larger, for example 09-06.

Is there a meaning to the hardware version, specifically could this be one sitting around for years when Siglent may have updated the hardware in any substantive way?

I bought it from Amazon (direct, not marketplace), which claims to be an authorized distributor from their response on the amazon site, but is not listed on the Siglent site.  Did I screw up?

I bought my SDS1104X-E back in June 2022 from an authorized distributor that is indeed listed on the Siglent site and it's also HW Version 01-05. This is a photo from its very first boot:

Their firmware release notes may answer the question.
V6.1.37R8: Be Compatible with a new VGA chip
V6.1.37R9: Fixed the problem: The skew of the two ADCs is not accuracy for hardware of 09 version (System Status shows Hardware Version: 09-xx). The other hardware version has no this problem.

It seems they changed VGA chips, and do not drop the old one yet. Consider chip supply shortage in the last 2 or 3 years, it makes sense.
May be they use MSB to distinguish the two VGA but displayed as decimal. That's why the number jumps from 01 to 09. :-DD

pope:
I'm pretty sure somebody posted (not too long ago) some information about what the Siglent serial numbers mean (date, version, etc...)

Got mine from an authorised  distributor about a year ago and the hardware version is 01-05 and FPGA Version: 2021-11-08

Whatever these numbers mean....

I also had (have?) some thoughts that the scope had been sitting around for a few years. Oh well...

When they change the hardware it's usually to make it cheaper/easier to manufacture.

It's not because they want to make it "better" or "faster" or anything like that.
