Agree, the video result is quite meaningless without proper termination, especially for square waves.  Dave has demonstrated this common mistake in his video.

It nice to have these options in life.   I remember being in my early 20's with a friend.   We use to go and look at the function generators and scopes with 10mhz bandwidth.   The whole time think we could never own any of this stuff.

If I could go back in time to the 90's and tell people I have something like the feeltech on my bench.   They would of laugh at me and called me a fool.

The last time I used my Feeltech was on a restore project for an old Pioneer FM tuner.   The original owner blew the the power amps out of it by touching the speaker wires together when the tuner was on.    He said to me that all the shops said that the FM tuner could not be fixed.  Beyond repair.

Well with my trusty Feeltech, Rigol scope I did a complete restoration and alignment the FM tuner afterwards.   It now enjoys a life at my brother place.

If you don't have the money for a nice Rigol or Siglent function gen, then get the Feeltech one.   You can still use it for your projects and have fun at it.  You don't need to spend the big money to have fun.

You shouldn't write off the new Rigol DG800 / DG900 series. Especially the DG811 is a very attractive model, provided the hack still works with the currently delivered firmware version. Without recalibration, it should be possible to "crank it up" to DG972 performance. With recalibration (of which currently none of us "amateurs" knows how it's to be done exactly ???), it could be turned into a full-featured DG992.

Cheers,
Thomas
