Modern active electronically scanned array (AESA) radars are a strong focal point of the global aerospace and defense industry. The performance of state-of-the-art AESA radar systems depends on the performance of the individual transmit-receive-module (TRM) assembled in the antenna array. Rohde & Schwarz offers new test and measurement solutions for TRM performance validation, enabling customers to maximize their radar system capabilities.
Typical TRM test cases can be covered with a single Rohde & Schwarz network analyzer as a turnkey solution, such as the R&S ZNA. If higher performance such as the pulsed noise figure is required, the R&S FSW signal and spectrum analyzer is added to the setup. When combined with the integrated calibration routine, R&S says this simplifies the setup, ensuring full accuracy and high repeatability. Users benefit from reduced test procedure complexity and a minimized cabling assembly.
The R&S TS6 TRM test library optimizes Rohde & Schwarz test equipment for top speeds, in combination with fast control handover. Due to fast frequency sweeps and multiple measurements within one pulse, the number of required TRM state changes is reduced and overall test time minimized, they say. All tests using the R&S ZVAX-TRM signal conditioning unit run automatically without interaction, including port multiplexing.
