Rohde & Schwarz AMIQ02 I/Q Signal Modulation Generator

The Rohde & Schwarz AMIQ02 is a baseband I/Q signal modulation generator engineered for precise synthesis of complex modulated signals in research, development, and production environments. It generates arbitrary I/Q waveforms and digital marker outputs for direct testing of components with I/Q interfaces or as a frontend to vector-modulated RF generators. The instrument supports advanced digital communication standards including WCDMA, HIPERLAN2, and IEEE 802.11a with exceptional spectral performance.
