In any case, if -60 dB at 3 GHz isn't enough for you, you should probably spend more than $70 on your network analyzer.

good point to notify us.. attached is noise floor for KC901V. comparing with picture from switchatbl, they are not far off, maybe spending more than $2K if even lower noise is needed

btw, i'm browsing aliexpress for Nano 3GHz 2N with 4" LCD but with SMA connection at the bottom (more convenient for my setup... or top? is there setting to rotate view?) with SMA cal kit and coax set, but it seems like no model for that, only N connector as in OP. if possible i dont want to play more with N adapter i want to "uniformified" my setup to all SMA to reduce cost of cal kit, adapter etc in long run... anyone know such version? i actually dont need another N-cal kit, its useless to me. if there is no direct SMA connection, then its ok with OP version i already have a few N to SMA adapters, but having another SMA cal kit and cables will be nicer i can make comparison among them with Kirkby cal kit, which is much better than $1 hung low 50 ohm version.
