I have a fully functional Agilent N8973A Noise Figure Meter in perfect working order for sale. It was purchased a few years ago, less than 5, I think. It has been in a controlled environment and used very little. This is a real Cadillac of Noise figure meters in its day. It is heavy. Pick up would be best, but I would build a crate to ship it in if necessary or drive to meet someone. Unfortunately, I have no noise source to go with it. It uses any of the standard HP noise sources. $2750 plus shipping. Thanks for looking. Dave, K4TO
