E36300 Series Programmable DC Power Supplies (E36311A, E36312A, E36313A)

nctnico:
Keysight has to fix this. What if there is a short interruption in the mains?

HighVoltage:
Here is another behavior, I have not seen before in an Agilent / Keysight PSU.

Make a parallel connection to all 3 outputs with external cables.
Output 2 and 3 are turned OFF
Limit Output 1 to 1V and 10 mA

Then turn only output 1 ON (Output 2 and 3 are still turned OFF)

Result:
Spike of 564 mA for a few micro seconds before it regulates to 10 mA after about 500 us

Or is this to be expected for such a setup?

TheSteve:
So a power outage is a bit of a scary thought if you have something expensive/delicate connected.
I am sure this actually applies to quite a few supplies/SMU's though.

I'm pretty sure this PSU is an exception in this price class. Think about when a power supply is tied into an automated test setup where you just can't disconnect the PSU.

I've checked a bunch of PSUs:
GW Instek PSP-603
Voltcraft PS-1302
HP 6012A
HP 66311B
HP 6572A

These PSUs range from 45W to 2000W so I think I got a bit of everything. Only the HP6012A showed a 1.5V spike on startup with the output adjusted to zero. The rest showed nothing at all.

Keysight DanielBogdanoff:
Quick update. There are a number of bug fixes in the works, especially around things that cause the supply to hang/crash. I'm working to get you all a beta code release, but nothing official will come out until the January time frame.

R&D is monitoring this thread as well.

Thanks for your patience!
