pascal_sweden:
Anybody out here who can do a video review about this new entry-level power supply series from R&S?

norks:
Elektor has a video review of the bigger brother HMC8043. The NGE appears to be a stripped down version of this so performance and operation is probably very similar, with fewer features.

rstofer:
It's pretty neat that all 3 channels are floating and all are 0-32V.  You can string them all in series to get 96V.
OTOH, it's odd that there is no chassis ground jack.

pascal_sweden:
Maybe the ground jack is available on the back connector with screws?

Is the jitter acceptable on switched-mode power supplies these days?
Or is it still better to go for a linear power supply?

From what I read on the R&S site, this seems to use a double regulation circuit -- switched mode followed by linear mode.  The new Keysignt low-power supplies work the same way.  It should be a very clean output but they don't state any noise specs on their datasheet. I like the look and functionality on these new R&S supplies, but I hate that they have a cooling fan inside.    I'd like to know what the fan noise is.
