I chose NGU201 to a large extent due to the fact it advertises headline "graphical capability." Well here it is in full glory.
1. You can't change the time scale
2. You can't pause it or look beyond 60 seconds into the past
3. You can't change vertical scale or the top/bottom value limits
4. It autoscales on you like "Jack In the Box" to stop you from getting used to the scale. You can't stop this
5. It does not respond to any touch input apart from changing the trace colours from a selection of 10 preset CGA era colours
6. If you correct your instrument time by two hours back, it locks up for two hours and you need to reset the instrument (or wait two hours)
7. Min/Max are in the format of "47.591 10 mA" and are randomly overlaid on each other
8. There is no average
9. Trace font is non-antialiased and jagged like randomly scaled down vector one
And this is just the beginning of the list.
It feels like designed by a kid that just learned programming and have no idea that people don't look at the charts to find max/min values with 7 digit resolution.
Even Chinese would be embarrassed of this GUI design.
Is this really R&S?!
