Vector Network Analyzers for LMR
“Vector network analyzers are valuable tools for radio technicians working with RF systems in the field or on the bench. VNAs can be used to characterize and tune frequency-dependent components such as combiners, isolators, circulators, duplexers, and filters, as well as verify antenna and transmission-line performance. Technicians can measure S-parameters and return loss, troubleshoot frequency-response problems, and use time-domain reflectometry (TDR) to check cable runs for integrity and locate faults, damaged connectors, “impedance discontinuities, or other sources of reflection. CMT offers compact VNAs well suited for both benchtop and field use.

Over-The-Air Antenna Test Systems
A new turnkey solution for customers needing to make far-field antenna measurements above 18 GHz. The over-the-air (OTA) antenna measurement chamber solution features a wide array of configurations depending on the user’s anechoic chamber requirements, antenna size, desired frequency range, and antenna positioner functionality.
CMT has partnered with MilliBox and Eravant to offer a complete OTA antenna measurement chamber solution for engineers needing to make measurements from 18 GHz to 220 GHz. Each OTA bundle can be configured with a set of 2,3, or 4 anechoic chamber cubes, depending on far field measurement requirements.
The measurement system is anchored by CMT’s 2-port 9 GHz Cobalt VNA and includes a 3D antenna positioner (Gimbal), sophisticated but intuitive measurement software, frequency extender modules, and other necessary accessories to fully set up a chamber for far field antenna measurements.
These comprehensive OTA solution bundles provide a low-cost, space-saving solution that is ideal for antenna testing applications across automotive radar, aerospace, satellite communication, and similar industries.
The OTA bundle is an all-in-one solution that provides everything needed to accurately test a large number of antennas. The combination of affordability and portability will enable multiple systems in a single lab environment for users to simultaneously test multiple antennas.”
