Hi guys,
At this time i don't need high R&D capabilities of my Lecroy wavepro oscilloscopes, and i am looking for some smaller oscilloscope.
I have some questions:
1. How good this siglent are in terms of DC offset and saturation? In Lecroy scopes you can offset you signal and "zoom in" up to several times needed piece of you signal without distortion. I mean this https://youtu.be/n_dXvpEV18g?t=155
2. Can someone provide screenshots of sin 200Mhz and 400Mhz with linear interpolation (without sinx/x interpolation) with 2Gs/s and 1Gs/s SR?
3. Can someone provide screenshots of fast rise meander with linear interpolation (without sinx/x interpolation) with 2Gs/s and 1Gs/s SR?
Thanks!
Hi,
Can anyone help me?

https://youtu.be/n_dXvpEV18g?t=155Changing the offset typically adjusts the front end amp offset. The Siglent offers, for example, +/-2V offset for a 100mV/div vertical sensitivity.
Regarding saturation, it's very dependent on front end amplifier recovery time. Typically, I simply wouldn't ever deliberately run a scope's front end outside vertical graticule range. The demonstration in the video you shared isn't showing what they're purporting to show by the way. The MSO5000 has a terribly noisy front end, at least 10dB worse than the Siglent in my measurements. They're also running that demo at quite a slow speed, 1ms/div. While it's interesting to see, they don't show it at higher speeds, there's probably a reason for that.
Anyway, I ran a very similar test for you. 1ms/div, 500mV/div down to 20mV/div in 10 bit. One zoom real time, the other is zooming in on a captured signal.

Edit: forum's done its bit to screw up the picture orders, I am sure you can figure out which is which, I've burned an hour on your questions already, I hope you don't mind.
