content: Will be harder to sell untested, if you include pictures of the exterior for an idea of overall condition that will help, and if you can run any internal self-test routines from the menu and report the result, you may get more bites.

content: Hello Vincent,Prices for this equipment go like this:1) eBay: A fully working unit up to 3GHz with fairly good cosmetic exterior will probably reach around 1200 Euro. You will need to include pictures showing some calibrated signal, though. Like having a signal generator producing a 1.5GHz signal which is shown in the same picture on the SA.2) eBay: A broken/untested unit (not tested, stated as broken, stated as "for parts", insuficient pictures, etc.) will probably reach around 600 Euro.3) EEVBlog: Again there are some differences...a) Known user of the blog (>100 posts) and/or with history of selling hardware: if the unit is stated as fully working, about 20% cheaper than eBay price = 1000 Euro.b) Known user of the blog (>100 posts) and/or with history of selling hardware: if the unit is stated as non working or with a description of known faults, about 20% cheaper than eBay price = 400-500 Euro (depending on the fault)c) Unknown user/new user (<100 posts): unit described as fully working - about 800 Euro if there is no hint of a scamd) Unknown user/new user (<100 posts): unit described as broken - about 300-400 Euro if there is no hint of a scamThis is my personal opinion, but I think it shows what you could (again, in my opinion) expect from your unit. eBay will give you higher return, but of course you have extra expenses (eBay fees), plus the usual risk associated with eBay/Paypal user protection, which is normally not in favour of the seller. On the other hand, people in this forum usually pay much less than on eBay, because there is no user protection at all and because prices are not as inflated as on eBay.Regarding your unit:1) It seems to boot and power on. That is good, as it does show that neither the power supply nor the motherboard are broken. Note that repairing broken HP/Agilent/Keysight power supplies is a real challenge due to an absence of schematics and the use of hard to obtain components.2) Not showing the spectrum on the unit does not allow evaluation if the most important component is broken: the YIG. If this component is broken, the cost of getting a replacement YIG is usually as high or even higher (!) than buying another working unit. The only way to prove the YIG is working would be to connect a known signal and show it on screen.3) The screen is scratched. A lot. That is not good...4) The floppy disk cover is missing. That is not good...5) Additional personalities are of little value without the corresponding memory card or disk.6) GSM/CDMA measurements are useless nowadays, which is why these devices (like the R&S CMU200, CRTU, etc.) pop up at a fraction of their original cost.7) Not showing the device in action because you don't know how to use it will cost you up to 50% margin on this sale. It would be well invested time learning how to use it!8 ) Restricting the potential buyers to just those living near you, so that they can test it, would again reduce your margin a lot!Regards,Vitor
