I picked one of these up off of Ebay recently. It is in very good condition, though needs a bit of love in a couple of places.
Dialing in the voltage is not 100% accurate... it gets within ~10mV. Which is the specification, but still made me a bit sad. Out of curiosity I started probing around the voltage programming circuit and I noticed that it is *not* as the schematic shows. The schematic shows 5 resistors in series with switches across each resistor. For example, for the 10s of mvs, it has:
R1: 20 ohms
R2-R5: 40 ohms
It even has a nice chart showing which switch gets closed with each setting. Only problem is that that isn't how it works. The schematic is correct that there are 5 resistors in series. But how it works is that the device connects has the ability to short out one section of the 5 resistor network. So it can short out R2-R5, for example, to give 20 ohms. Further, one side of the short is always connected to either side of R1 (inner for odd settings, outer for even settings).
Just thought I'd post this in case anybody else gets confused by it. I will mention that the manual shows a picture of this section that does not quite look like Robrenz's section - instead of having a pot with shaft orthogonal to the face of the instrument, it shows a pot that is parallel with the ground and face of the instrument. So it's possible the manual on Agilent's website is out of date. I also noticed that the manual shows this device having a neon power indicator, whereas as far as I can tell it has no power indicator whatsoever.
One other thing: Robrenz is right that he does not have the original feet/stand for his device. It originally had two plastic bits that would clip into the square holes. The usefulness of these is that they hold the stand in a rigid place. Not the end of the world, but they're nice to have.
