  • Page 52: Getting Started

    R&S SMU200A Introduction - Getting Started 2 Getting Started Introduction - Getting Started The main field of application of the R&S SMU is the generation of digitally modulated signals. The R&S SMU uses I/Q (vector) modulation. Digital data streams are converted to an I/Q baseband signal. The baseband signal is then D/A-converted and modulated onto the desired RF carrier frequency with the aid of an I/Q modulator.
  • Page 53 Introduction - Getting Started R&S SMU200A In the R&S SMU, a digitally modulated signal can be generated in two ways: 1. The I/Q signal is generated internally in the R&S SMU. In this case the instrument must be equipped with at least one baseband generator (option R&S SMU-B10) and at least one baseband main module (option R&S SMU-B13).
  • Page 54 R&S SMU200A Introduction - Getting Started 2. An external analog I/Q signal is directly applied to the I/Q modulator of the R&S SMU (Analog Wideband I/Q operation). In this mode, the entire bandwidth of the I/Q modulator can be utilized. The various capabilities of the baseband section (AWGN, addition of signals, etc) are disabled, however.
  • Page 55: Baseband Section Of R&S Smu

    Baseband Section of R&S SMU R&S SMU200A Baseband Section of R&S SMU The baseband section of the R&S SMU is fully digital and contains the hardware for generating and processing I/Q signals. The baseband section may contain two paths. Baseband generator (option R&S SMU-B10): The generator produces baseband signals. It contains modules for real time signal generation and an arbitrary waveform generator (ARB).
  • Page 56: Rf Section Of R&S Smu

    R&S SMU200A RF Section of R&S SMU RF Section of R&S SMU The RF section of the R&S SMU may also contain two paths. An RF path is configured by installing a frequency option that comprises all required modules including synthesizer, output section with I/Q modulator and attenuator.
