The swept noise figure test solution covers 100 kHz to 50 GHz and offers a wide variety of resolution bandwidths for every application, even for measurements on narrowband DUTs. If results are questionable, use the analyzer to check the test setup for radiated interference or nonharmonics. Measurements on frequencyconverting DUTs are supported by an external generator.

The Signal Analyzer R&S FSQ or the Spectrum Analyzer R&S FSP or R&S FSU can detect and analyze interference sources.
