[R-390] R-390 Related Activities

[Jerry Kincade]

Since the subject of sweeping receivers and filters has come up again, and
at the risk of getting my typing hands severed at the wrist for mentioning
this, I put my pet HP-3325A up for sale on that awful unmentionable place
yesterday. Much like the 3336B, the 3325A is an outstanding sweeper up to 20
mHz if anyone wants to get into this test methodology.
