Hello,while getting closer to my first really phase noise measurement setup with a HP 3048a , I cant stop looking at products from this decade. Does anyone have an idea how much the microsemi products 5120a and 53100a costs? On the datasheets it looked like made for newbees like me: Press one botton and get all answers you want.  Thx and Kind regards  Norman

Hi When I last bought 3120A’s they sold for about $15K. The 53100A was in the same range before it moved over to Microsemi. One would *guess* the price went up. The 5120A is (essentially) obsolete at this point. Microsemi shows it in the “not recommended” category. I believe the last one we bought was up around $30K. That was a very long time ago. I could easily be off on that price. At least to me, the “big deal” with the 3120 and 53100 is on the time domain side. There are other (even more expensive) phase noise boxes that are more capable. The 3120 has a very limited input frequency range. The 53100 is significantly better, but still not into the GHz like some other devices.
