Hello,
in the video from Batterfly.com is at time 0:19
Memory Depth 100 Mpts/ch and 400 Mpts/ch.
I think ebastler rightly criticizes this.
The data sheet of the SDS7000X HD shows the standard: 500 Mpts/ch. Would you be satisfied if you bought an SDS7000X HD and only got 125 Mpts with four channels?

I'm not asking for an extra chapter in the video. At 00:19, simply don't write in big fat letters "400 MPts/ch", but write in equally fat letters "400 MPts". How would this make the 2-minute video any longer or more difficult to grasp?
It's not the end of the world and does not devalue the scope, but it is a factual error in that video. I don't get it why you can't simply say "Oops, indeed, they got that wrong", but have to come to Siglent's defense. It is not the first time. And it is a reflex which I just don't get in a user who otherwise makes many valuable and well-reasoned contributions.
Hello,
I still think the probability of such a "memory" error is very small, but the manual on page 63 says so:
"Under the full Memory Depth, SDS3000X HD can still operate at full speed sampling at
timebases <= 10 ms/div which provides high resolution captures for long time duration events."
If you use ch1 and ch3 with 200 MSa then you get only 2 GSa/s.
So there is definitely a mistake in the user manual. I just hope that the above sentence is correct. But as I said, it's a very small hope. A spark of hope.

Hello,
You're right, there are bad mistakes and insignificant mistakes. The Mpts/ch error is insignificant here, because everyone here knows how it really is. Whether the SDS3000X HD 400 Mpts is an error and it is actually 2 * 400 Mpts is a significant error for me, because I have ordered an SDS3000X HD and would be very happy if it had 2 * 400 Mpts. Unfortunately, however, I think this is unlikely. But as our Secretary of State said, you can have a ham of hope.

Mind you, 100MPts is a lot.
I was expecting that you would hack this thing and unlock it all for free?The Scope costs just over €4000 and has the following options:
SDS3000HD-16LA 474,81€
SDS3000HD-FG 355,81€
SDS3000HD-PA 1010,31€
SDS3000HD-1553B 391,51€
SDS3000HD-CANFD 391,51€
SDS3000HD-FlexRay 391,51€
SDS3000HD-I2S 391,51€
SDS3000HD-Manch 391,51€
SDS3000HD-SENT 391,51€
SDS3000HD-ARINC 677,11€
Do you need them all?
If I look at the list now, then just 2 options would currently be interesting and useful for me.
And now, hand on heart, who feels the same way?
Hello,
what I don't know is what the situation is with the SDS3000X HD or SDS2000X HD with the total segmented memory. Some devices have more memory available with segmented memory. How much segmented memory is available on the SDS2000X HD?

Who knows, one day I might get my hands on something that uses one of those protocols and think it fun to try it out. I would neither want to pay a lot for some fun nor wait to get the feature.
@baldurn:
I don't know when I might need it, so I want it for free instead of buying it.
Interesting point of view.
QuoteWho knows, one day I might get my hands on something that uses one of those protocols and think it fun to try it out. I would neither want to pay a lot for some fun nor wait to get the feature.
No problem on a siglent - Therefore you can use all options for a limited time and 30days should be more than enough to try it out.
And the good thing is:
Time only runs out the moment you use it.
Used today, one day gone.
Use it again in 2 months, one day gone.
Not like with Lecroy:
I can request trial licenses, they are also valid for 30 days - But the time runs out the moment you install them on the scope.
It's not a worthwhile upgrade if what you have meets your needs. Did you "improve" your 2K HD?
Hello,
I wonder if you can get close to a Picoscope 4262 with an SDS3000X HD with ERES and filter?
Best regards

You can't. You can get better than most 12 bit scopes, but you cannot cheat physics and math..
Both Performa and myself published some measurements before...
EDIT:
on 1ms/div:
2000xHD with ERES3 I can get 20uV Stdev. noise floor
6000 H12 with ERES 4 I can get 25uV Stdev.
what I don't know is what the situation is with the SDS3000X HD or SDS2000X HD with the total segmented memory. Some devices have more memory available with segmented memory. How much segmented memory is available on the SDS2000X HD?
I could afford 3k HD, provided I could unlock the bandwidth for free, but it just wouldn't be enough for what I have in mind.

2000xHD with ERES3 I can get 20uV Stdev. noise floor
6000 H12 with ERES 4 I can get 25uV Stdev.

A call for Bin-Files as new Siglent HD-Models:
I am very interested to get a BIN file of full possible sample size as may 100M or 200M or even more as like to see the 1/f noise or spurs.
As from all new 800 HD, 1000 HD, 2000 HD, 6000 HD & 7000A HD models
May with the following settings:
- Input shorted as as for a) 50E or b) 1M
- May the ERES to consider, currently to look at full BW of the DSO
- Lowest Y division as 1mV or 500uV
- As on my SDS2k + (10 bits), requires to set the time divisions may in the 2..5ms range,
anyway the time division icon will display current sample size
- save it as BIN file and zip it please
and lets attached....

I think I found another "error" on the Batronix site regarding the new siglent scopes.
The SAG1021I module is described as a 25Mhz generator, the 800X HD and 1000X HD are also described as 25Mhz generators in conjunction with the corresponding license.
The 3000X HD, however, is described as 50Mhz, despite the same hardware.
....the frequency depends on the frequency defined by the oscilloscope FG option.
Wait a minute...
