The MS46121A 1-port USB VNA is a small (USB power sensor-like) 1-port VNA series with two frequency ranges from 40 MHz to 4 GHz and 150 kHz to 6 GHz. A user-supplied computer supplies power and control to these VNAs through a USB cable.

The MS46121A comes standard with an N(m) connector for easy connection to N(f) connectorised devices such as antennas and cables. ShockLine software controls the MS46121A and provides the tools and graphical user interface for easy debug and testing of 1-port RF devices. ShockLine is compatible with Windows 7 or Windows 8 (32- and 64-bit) operating systems making it very easy to integrate the MS46121A into most test application environments. For remote programming, the MS46121A supports a complete SCPI command set as well as LabView, LabWindows, Matlab, C# and other software interfaces through an IVI-C driver.

MS46121A VNAs support efficient multisite testing by enabling up to sixteen 1-port VNAs to operate in parallel from a single host computer using a powered USB hub. Using multiple MS46121A VNAs in place of a single VNA and a switch box setup improves throughput by enabling true parallel testing of devices.

The 1-port USB VNA is compact and lightweight, making it well suited for applications such as near-field antenna testing where direct connection to the DUT is an advantage. Eliminating RF interface cabling improves calibration stability and measurement quality while reducing the cost of test for such applications.
