Suggestions for a good second-hand LA?
(1/10) > >>
mbalmer:
I recently purchased an HP/Agilent 16702B without knowing about the (apparently) infamous corrosion issue due to the plastic runners used on the bottoms of the module boards. I went back and forth with the equipment company that sold it (it was sold as fully functional and non-DOA) exchanging boards with them -- every single one they sent me had corrosion issues that were clearly visible or were invisibly damaged to the point that the boards threw errors.

They were tremendously gracious with me on this, and I don't fault them for not knowing.

The mainframe was sold originally with a 16534A 2Gs/s, 500MHz two-channel scope board and two 16717A timing and state modules. Upon first boot, I immediately ran the self-test suite. The mainframe passed, and the scope passed, but one of the two 16717s failed its VRAM tests. The other board passed -- for a little while. It started throwing Comparators and ZoomChipSelTest errors -- about which I've posted in another thread in the (vain?) hope of trying to revive it.

The company sent me additional boards in the hope that another one would pass, but to no avail -- and now I have a total of five of these boards, none of which pass their self-tests.

That said, I'm looking at other possibilities for a good second-hand LA.

I've got an opportunity to get my hands on an Agilent 16902A that has a (potentially) faulty HDD -- the person selling it said that they can't test the logic analyzer module (a 16950B) because they can't get the system to start. Apparently, it blue-screens during the boot process. If that is indeed the case, that the thing just needs an OS reinstallation, would a unit like this be something more viable?

If not, are there any other suggestions for something that doesn't cost me several thousand dollars?

If you have room and want a NASA/Space-X/LLNL grade LA what about the HP 3314A?  I have one older than my 30+ YO son and it works flawlessly.

Looks as cool as f'k on the bench too.
mbalmer:
A 3314A? Isn't that a function gen?
BillyO:
My bad.  Wrong awesome device.

This is what I was aiming at.  The probes plug in the back, and IIRC you can have 32 of them.



HP 1651A.

Yeah, not the gorgeous SG.

It is.  I made a bad all over the forum...
