ZEEWEII DSO1511G not showing square at 2mhz when other people's do.
(1/5) > >>
slikvik:

Calibrated my probe as per the manual and following along exactly to the calibration in Adrian's Digital Basement video.


* It looks fine a 1Khz (see attachment)
* Switching to 2Mhz looks like the second attachment.
* Adrian's Digital Basement did exactly the same and got a much better square when viewing 2Mhz from the signal generator. (3rd attachment)

The review on this forum also showed a pretty good 2mhz square: https://www.eevblog.com/forum/testgear/dso1511e-review/

Do I have a dud version of the device?

What's your signal generator? - it could be caused by it.

If you are using the internal signal generator, I can't see how that is connected.

The generator is probably the one in the scope but OP should confirm that.

Use it's own signal generator, it knows up to 2Mhz.
Why and what is the ground of your signal generator connected to??
