You are bidding on a used Anritsu Scorpion-series MS4623B 10 MHz - 6 GHz Vector Signal Analyzer.   The analyzer has the following options:
3B                        2nd source/3rd port/step attenuator
4                           noise figure measurement
8                           harmonic measurements
11                         connector type N(F)
13                         IMD measurement

This analyzer has been refurbished.  It had lost both memory backup batteries, so were the boot and application software gone.  The system was recovered from zero point, but the serial number has not been inserted, which can be seen on the service log.  The LCD display has been changed and also the 2nd source module. After changing the 2nd source module both sources were ALC calibrated.
The analyzer calibrates and measures in normal way.  This is a full 3-port VNA:  you may see in pictures a S31 measurement of the transmission path formed by two small antennas connected directly to ports 2 and 3, as well as S33 measurement with SWR format at port 3.
The analyzer has also noise figure measurement option, a NoiseComm NC346A noise source is included with the instrument.
This is a great instrument for duplex filter tuning, mixer characterizing, amplifier gain/NF measurement and many other works.
