RF test system characterizes radar modules


The R&S TS6710 test system from Rohde & Schwarz is a flexible, turnkey standard solution for manufacturers of AESA radar equipment. Its modular architecture allows it to be configured for product development or for use on production lines.

Predefined test cases and the compilation of complete test sequences simplify operation and the user can also adapt all test cases individually to specific customer requirements. When configuring a test system for a customer, Rohde & Schwarz does not require any detailed information about the modules to be tested  so users do not need to specify the bandwidth of the particular module they are working with.

The R&S TS6710 can characterize the 25,000 measurement results of a transmitter-receiver module (TRM) in less than four minutes. The compact test system, whose frequency range extends from 1 Hz to 24 GHz, consists of three instruments: an R&S ZVA network analyzer for RF measurements, an R&S OSP-TRM control platform for RF signal switching and conditioning, and an R&S TSVP test platform for TRM control and supply.

The system can measure the S-parameters for all phase attenuation combinations, the noise factor, output power and intermodulation as well as spurious emissions. Short measurement times are an enormous advantage especially in production, where only about 2500 measurements per TRM are required. Under these circumstances, an R&S TS6710 can complete a test run in less than 15 seconds. Two modules can be tested at the same time with a single system. Optionally, users can even characterize as many as eight DUTs in parallel.

The R&S TS6710 takes relevant safety and secrecy regulations and requirements into account. To configure the system for a customer, Rohde & Schwarz does not require detailed information about the modules to be tested. The operating frequency, for example, is a core parameter of AESA radar systems. With the R&S TS6710, the manufacturers do not have to reveal it. Since the frequency range extends from 1 GHz to 24 GHz as standard,

All test cases can be specifically adapted as required, and the source code for the test cases written in C# is included in the system when it is delivered. The user can compile complete test sequences using the system software.
