Haha  ;D

I'm passing this along to the team for feedback!

When these are addressed, I'm willing to give EL30000 series a serious consideration.

rvalente:
Still following this terrible black design trend... ahhh ugly as hell to stare at

Berni:
Okay most of it are features that they just didn't put in, mostly a mistake in market research there, but the remote SCPI interface locking up is a rather big deal.

I have had plenty of weird bugs and issues with remote control interfaces on test gear. Pretty much anything i had out of China has had at least some sort of quirk in the remote interface. You have to randomly stumble on them and find workarounds, usually works in the end. Yet this is Keysight we are talking about, with the reputation they are holding you would expect the remote interface to be almost fully bug free, let alone have such a serious bug as this.

Recent Keysight hardware is just not as great as in the old days. There are plenty of other examples discussed here:
Disappointing performance of B2962 power source
Drift of 34470 DMM due to ACAL
Bugs with bursts in 33522 function generator

Keysight DanielBogdanoff:
Sorry for the delay, took a few days off and am catching up!

@niner_007 the R&D team would love to chat if you're willing, I'll send you a PM.

The SCPI lockup issue is something we haven't seen before, we've been doing nonstop / no delay commands without issues, so the team would like to take a look / chat and see if there's a bug, but we suspect it's just your load and we want to get it replaced.

Regarding battery testing, from R&D:
"
The EL30000 Series does not currently have a dedicated battery test feature, but we are considering adding it through a future firmware release.  Meanwhile, you will need to use a PC to control the load and stop the discharge before the battery reaches its cutoff voltage.
"

Obviously we'll need to get the comms issue worked out for your unit.

From Bill Griffith, one of our power folks:
"- The current definition for undervoltage better is for testing power supplies. The latch mode assumes the input voltage starts low, and rises toward the undervoltage limit at which point the load turns on and stays on regardless of voltage. E.g. once live stay alive.

- I wrote a simple program to test batteries with an undervoltage cutoff: https://blogs.keysight.com/blogs/tech/bench.entry.html/2021/05/03/battery_and_celltes-HXQ1.html

- Loads potentially have two sets of ranges, one for the load and one for the measurement system. You do not want to auto-range the load as it would affect the source. It might be beneficial in some cases to auto-range the measurement system. However, it is much simpler just to tie the load and measurement system together. I personally, prefer the ease-of-use of a single setting for high, medium, and low range.

- For lower power BNC connections – I cut off a dual banana plug. You used two of them in this video: https://youtu.be/FM7dWAC6wok?t=22 I personally like the front connectors – we used them to test the 20 A output of the power supply
