High-performance sampling system with 1.2 GSa/s sampling rate and 16-bit vertical resolution.
Innovative TrueArb technology, based on a point-by-point architecture, supports any 8 pts ~ 8 Mpts Arb waveform with a sampling rate in range of 1 uSa/s ~ 75 MSa/s.
Where does the limitation of 75 MSa/s come from, while it uses a sampling system with 1.2 GSa/s?
For which signals does it use 1.2 GSa/s? And for which does it use less?
Why you would want to use a variable sampling rate that goes down to 1 uSa/s?
Isn't it better to just always use the highest available sampling rate for best results?
Or is it because of memory limitations, when you want to store longer periods?
But then again, isn't 1 uSa/s a bit on the low side?
Note that the unit will only let you set a "frequency" of up to 4.577,637kHz. But frequency of what? If you divide 75M by 4.6k you get 16,384. So apparently when you set the frequency you are telling the unit how fast to cycle through 16,384 samples.
So what happens if you have more than 16K samples in your sample set? I don't know.
Hello all.
Another nice new firmware update on the Siglent SDG2000X generators. It adds some new features - such as the ability to Combine CH1 & CH2 - as well as fixes some bugs.. Here is the FW link and what it does:
You can download the firmware from the below URL:
http://www.siglentamerica.com/USA_website_2014/Firmware&Software/firmware/SDG2000X-P21R2.rar
The new firmware details:
-------------------------------------------
1. Added Waveform Combination function, to support combining CH1 and CH2 from internal to generate complex signals such as sine + noise and two-tone. The set path: Utility | Output Setup | Wave Combine
2. Added mode selection: “Phase-Locked”and “Independent”. In “Phase-Locked” mode the generator resets both channels every time the frequency is changed to maintain synchronization automatically.
In “Independent”mode the generator will not reset any channel when the frequency is changed; the phase difference between channels is random. The set path: Utility | mode
3. Fixed several bugs
a) Can not remove files with illegal characters
b) In burst mode, press the soft key for cycles, it changes to infinite right off the bat
c) External modulation input inverted compared to convention
d) Can not remember the clock source setting
e) Some unexpected glitches when enabling the output or change the parameters
As an owner of one of these generators, let me thank you for posting this. It is definitely a plus to get both a heads up on updates *and* an explanation of what to expect when I do the update.
Thanks!

Lots of good fixes there - can't wait to get it installed!
Dear Siglent! Thanks for the good work!
What about the fix for no interpolation on SDG2042X between the last and first sample in a recurring DDS waveform.
Could this be fixed in the next firmware update?
d) Can not remember the clock source setting

Heads up for those of you that have hacked your SDG2000X, Siglent have added a username/password required for logging in through telnet potentially closing the hole. If you have already hacked it before the update you are probably fine, but I couldn't say for sure as mine wasn't hacked.
