With high-precision measuring instruments and automated test scenarios,
Reduce TRM test complexity, cost, and measurement difficulties.


Active Electronically Scanned Array (AESA) radar is a technology utilized in the global aerospace and defense industries. The performance of an AESA radar system depends on the performance of the individual transmit/receive modules (TRMs) assembled into the antenna array.

On the 26th, Rohde & Schwarz (R&S) unveiled a TRM performance verification solution that maximizes the performance of AESA radar.

Typical TRM test requirements can be addressed with the R&S ZNA single network analyzer. Pulse noise figure measurements can be performed with the R&S FSW signal and spectrum analyzer. The calibration method employed simplifies the measurement setup and ensures high accuracy and reproducibility. Users can simplify testing procedures and reduce the cable connections required for measurements.

The R&S TS6 TRM Test Library optimizes R&S test equipment for high-speed control switching and maximum measurement speed. High-speed frequency sweeps and multiple measurements within a single pulse reduce TRM state change requirements, minimizing overall test times.

The R&S ZVAX-TRM unit also enables full automation of all tests, including port multiplexing. In particular, the R&S TS6 TRM test library's "Calibration Routine" function collects all calibration requirements required for testing and performs optimized, high-precision calibration.

Support for multiport calibration units enables efficient calibration of multi-port devices under test (DUTs). This scalable solution combines simple test setups with high-level automation capabilities, ensuring reliable and reproducible measurements. This solution can be used in a variety of environments, from manual component testing to module characterization and automated production testing.

In addition, the combination of the R&S TS6 TRM test library and the R&S TS6710 TRM radar test system allows for accelerated TRM testing, including ultra-fast switching between measurement and DUT programming. Complete TRM characterization, which previously required hours of measurement time, can now be completed in just minutes with R&S' TRM system.

The various variables typically applied in TRM design vary depending on the radar and are considered confidential. Furthermore, each TRM must be controlled via specific interfaces, protocols, and I/Os for testing. The R&S TS6 TRM test library provides an open software interface for TRM control, allowing the entire test configuration to be performed on the measuring instrument itself.

The R&S Compact TSVP test system option provides a versatile platform supporting efficient, flexible, and fast control interfaces and digital and analog measurements. This configuration enables extremely short test times with intuitive setup, without the need for FPGA (Field-Programmable Gate Array) programming.
