Test sol'n generates phase-coherent signals up to 20GHz

Rohde & Schwarz has developed what it describes as a compact solution with up to four RF outputs for generating phase-coherent signals up to 20GHz. According to the company, the test solution is aimed at aerospace and defence applications, which can be used to test multichannel antenna systems including phased array antennas.

At the heart of the system is the R&S SMW200A. Equipped with the R&S SMW-B90 phase coherence option, the test solution can phase lock modulated or unmodulated signals. The high-end vector signal generator has two RF outputs. Two other RF outputs up to 20GHz can be economically added using two R&S SGS100A signal generators and two R&S SGU100A upconverters.

The entire setup takes up only six height units and is significantly smaller than comparable solutions, noted the company. Users can also easily configure the setup on the intuitive R&S SMW200A touchscreen, added Rohde & Schwarz.
