How is the web based control on the keysight?
Also did you find the logging feature any useful ? Does it do any sort of averaging or is it instantaneous? Also what is the min time step/offset?
I used Keysight's software only briefly, but it worked very well.
To me the interface of the power supply itself is quite good, so I didn't see the need to invest in the software.
The logging is very useful to me and I used to capture battery charge curves. I don't recall averaging being implemented in the supply. It can save all data in .csv format to a pendrive, so Excel or other spreadsheet software can manipulate data quite nicely.
The sample interval goes from 200ms to 60s and the supply nicely calculates the time duration depending on the sample interval, the different collection of logged information per channel (P, V, A) and the memory available.
