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 did some "tricks" using the advanced features:

Anyway, for regular use these features are too cumbersome (at least to me).

Can't tell anymore, guess you'll have to read the manual ;)

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.

Oh, the "whys" of the datasheets... The information is there not to be an axiomatic truth, but instead each speck of data must be slowly inhaled while carefully performing a deep search inside oneself to find the true metaphysical sense...

Nice tricks on emulating a load, but it indeed take too much work

Thanks for the info . I guess measurements/log performed right on the instrument are more accurate (in time/timestamps) than reading back through lan/pyvisa etc. since they avoid the command overhead and jitter. Although 200ms is not too fast. Have you found this restrictive?

It is restrictive if I want to log fast current transients, but for that I have an oscilloscope.

I simply live with the fact this is a pretty good power supply with a built-in 5Hz DSO - plenty for what I use.

Hi, is the (transformer?) hum normal? It appears as soon as the device gets plugged in.

My unit also likes to hum.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

It is certainly part of the advanced pre-heating circuit that keeps the backlight always on |O

(My only real pet peeve with this otherwise marvelous bit of kit)

Mine is always silent except if I run a heat gun on the same circuit. I get the same buzz/hum on some other HPAK supplies as well with the heat gun.

It doesn't just him when plugged in, it draws about 10W on standby. It really does need a proper physical power switch.
