KC901V Hardware 1.0.4. 1.Problem. 2. Upgrade software?

By AndreyG •  2017-07-24 12:53:01 •  703 clicks
1. I got one of your first KC901V devices. Software version V.1.0.0. Is it safe to upgrade to latest software?

2. My device has problems - noise of plot at high frequencies which makes Smith Chart practically unusable. See attached image. Is there any way it can be fixed?
