Interaction of Intermodulation Products between DUT and Spectrum AnalyzerSource: Rohde & Schwarz GmbH & Co. KG
This white paper describes the interaction between intermodulation products generated by a device under test (DUT) and intermodulation products generated internally in a spectrum analyzer. The overall intermodulation distortion may be too optimistic or pessimistic. Examples demonstrating cancelling IM products and necessary steps to avoid an influence of the spectrum analyzer on the measurement results are outlined.
