Agilent is making some nice stuff. I’ve got one of their Function Generators and it’s a breeze to use, as opposed to the old HP 8116A with it’s indecipherable controls.
I have little to no experience with their electronics test equipment such as you describe, but their chemical analysis equipment has always been "best of breed" (gas chromatographs, liquid chromatographs, mass specs, GC-MS, and more).
