Agilent also makes some real deal new power supplies.
Actually, they are all made by TDK Lambda, but they are Agilent /Keysight branded.
I just finished a project where I needed to charge up some single Maxwell Super Capacitors with 100A up to 2.7V
This Agilent N5741A was perfect for it.
Even connecting two of the Maxwell Super Capacitors in series and charging them up to 5.4V at 100A constant current was something really cool to watch. The current did not even fluctuated 0.1A.
Here are some pictures of my N5741A. Notice the huge wire connections in the back with real M8 size screws.
And this one has GPIB, LXI and USB
