Page 34 would appear to indicate the E36300A series will be replaced with a E36300B series. Possibly a hardware update?

Good catch. The specs don't seem to be any different and the picture on the catalog is that of a A version, so I am not sure what the differences are (maybe a fix to the startup spikes and the not-really-off issues).

On te series mode issue, Keysight has reproduced the issue in the US, then I got a "We are aware of this and R&D is currently working on it."

I have asked if this is a firmware fix or a E36300B fix and will report back if they commit to an answer.

It's good to hear that there's a "B" version in the works. From the findings thus far, it seems the "A" version hasn't been quite where it should.

If the power on spikes don't get fixed in the A version through a firmware upgrade I expect Keysight to take my A version back and exchange it for a B version (or do an upgrade). It is not a particulary cheap power supply.

The E3610x series B version was just released, the spec sheet mainly shows notably reduced ripple under performance specifications (around 50-70% reduction is rms and pk-to-pk for most models). So that leaves me wondering why the B revision, rather than just keeping the same model and tightening the spec.
