The MS46122B series from Anritsu has three PC-controlled Compact ShockLine Vector Network Analyzers operating from 1 MHz to 8/20/43.5 GHz. These 2 port compact VNAs have a sweeping speed of 220 us per point with a dynamic range of up to 100 dB and a directivity of 37 dB. They are low-cost full-reversing VNAs targeted at RF and microwave applications in manufacturing, engineering and education. These VNAs are in packaged in a very compact 1U chassis and are externally controlled via USB from a user supplied PC running the same Graphical User Interface (GUI) software as the rest of the ShockLine family of VNAs. The series does not have any on board memory which simplifies its use in secure applications.
