It might be wise to revisit your post with edits.

Hi tautech,thanks for the correction, post has edit. I have already noticed that the SDS1000XHD summary mentioned the memory depth is 100 Mpts/ch.

however, when comparing the full datasheet, it states: 100Mpts (interleaving mode). Things get bit confusing here :palm:

According to the acquisition hardware config of SDS1000XHD (2 or 4 channels shares one ADC), this provides some clues that the SDS1000XHD may actually have shared 100M memory for all channels. Also, SIGLENT makes this kind of paperwork mistakes often :palm:.

Before actually using the machine, this can only be a reasonable guess. Let me know if you have any definite info on this, then I'll revise the post again.

4th line down on the Chinese website clearly states 100 Mpts/ch so despite what other info states I believe for now we should work with this.  ;)
Hence the basic info on specs posted in the OP of which I will change if proven incorrect.

Tankj:
The full data(chinese one) also clearly states 100Mpts in interleaving mode.

So far, Siglent gives conflicting information. We can't tell which is right, only think of these as two possibilities.  ;)

I'll attempt to get answers.

1000XHD has total of 1G sampling rate capacity(1G for 1CH, 500M for 2CH, 150M for 4CH),
2000XHD has total of 4G sampling rate capacity(2G for 2CH, 1G for 4CH).
(snip...)
Personally, the only complaint I have is the 4-channel model still shares that 1G sampling capacity, which means only 250M for full channel use.

I believe that 150M is a typo which only adds to the confusion.   ;)     
An excellent comparison nonetheless.   :)
