The MS46121B from Anritsu is a 1-Port USB Vector Network Analyzer that operates from 150 kHz to 6 GHz. This compact computer controlled VNA provides performance and accuracy for 1 port measurements and can directly connect to the device under test. It is ideal for applications in manufacturing, engineering and education.
The MS46121B 1-Port VNA are available in two configurations, 40 MHz to 4 GHz and 150 kHz to 6 GHz. The two MS46121B options are both available with 120 microsecond per point sweep speeds and a measurement accuracy of +/- 0.5 dB (-6 dB offset, typical), making them suitable for testing passive devices.
These VNAs are externally controlled via USB from a PC. Up to 16 independent VNAs can be operated in parallel from the same computer running the ShockLine software. This enables true parallel multisite testing of 1-port devices improving throughput over traditional single VNA and switch matrix test solutions.
Adding option 21, Scalar Transmission, will allow scalar measurements (magnitude only) between multiple MS46121B VNAs. The series does not have any on board memory which simplifies its use in secure applications. The combination of lower cost, small size, good performance, and parallel operation make the MS46121B series VNAs ideal for passive 1-port device test applications where performance and multisite testing are desired.
