Anritsu has introduced the ShockLine MS46121A series of 1-port USB vector
network analyzers (VNAs) that bring the price, performance, and ease-of-use
advantages of Anritsu’s patented ShockLine VNA technology to an extremely
compact package. Two models with frequency coverage of 40MHz to 4GHz and
150kHz to 6GHz are powered and controlled via a user-supplied computer to
simply and cost-efficiently test cables, antennas, and other passive RF
devices where 1-port measurements up to 6GHz are required.

To maximize throughput in manufacturing, engineering, and education
environments, a single computer connected to a USB hub with enough ports can
run up to 16 different ShockLine MS46121A VNAs. Sweeps can be conducted at
100 microseconds per point and the MS46121A VNAs have a corrected
directivity of 42dB so engineers have greater measurement confidence. Wide
dynamic range and multiple IF bandwidths optimize measurement setups to
shorten test times and maximize throughput.

The MS46121A series is controlled through the powerful ShockLine software
that provides the tools and graphical user interface (UI) for easy debug and
testing of 1-port RF devices. It also provides remote programming
capabilities that enable the ShockLine MS46121A to be easily programmed and
integrated into manufacturing applications.

Anritsu has developed two MS46121A models for specific measurement
requirements. The USB VNA with 40MHz to 4GHz frequency coverage is well
suited for base station antenna testing where limited frequency bands are
required. The wider frequency range model covers 150kHz to 6GHz and is
designed to test cellular handset antennas and other devices that must
transmit and receive on multiple frequency bands.

With the introduction of the MS46121A VNAs, the ShockLine family now has
five series, all of which bring unprecedented value and performance to
cost-sensitive engineering and production environments. The other ShockLine
series are the MS46122A low-cost full-reversing 2-port VNAs, the MS46522A
2-port series with coverage of 50kHz to 4.5/8.5GHz, Economy ShockLine
MS46322A 2-port VNA for measurements up to 40GHz, and the MS46524A 4-port
VNAs for differential and multi-port device testing.
