This explains the fast startup time of round about 5 seconds in the video from Keysight.
The 12A and 13A seem to be the same size and features as the TTi MX100TP I just purchased, but with a lower load capability and at a higher price. What am I missing? The 11A is the same price, but far less capable.
Some images from the Service Guide:

More software support (BenchVue, as opposed to only drivers to interface with your own software)? Stand-alone logging of data?

Specs show 0.04% +3 mA and 0.25% +80 uA readback accuracy.
Given that stand-alone logging and BenchVue software are not features I want or need, the TTi is better value to me. And, not that it matters to me, the MX100TP comes with GPIB.
Resolution is nice so at least you can see small changes. I expect the logging feature on these new Keysight PSUs is extremely helpful for low power devices to determine the power profile.

I suppose one could use the last two digits to feed entropy into a random number generator, so it's not entirely useless.
Either way it is not trivial to measure these kind of low currents going into a ciruit without dropping a significant burden voltage or deteriorating the power supply's out impedance so I'm happy with what I can get.

According to a picture in the Service Manual they use a STM32F4. This explains the fast startup time of round about 5 seconds in the video from Keysight.
There is already a firmware update available on the website. No wonder to see a USB DFU Updater.
And after a quick look in the Firmware file I think I found some text that belongs to an easter egg
It's like Keysight was listening when I wrote my post a while back about "Why does no-one make a decent power supply"
I have been on the brink of getting a TTi, But I think I will get the E35312A instead.
The low current feature is great!
