The Rohde & Schwarz FSMR3 is a measuring receiver that combines signal analysis and demodulation capabilities across 20 Hz to 3.6 GHz. It delivers precise signal characterization for laboratory, production, and field environments through spectrum analysis, power measurements, SNR assessment, adjacent channel power evaluation, and occupied bandwidth analysis. The instrument supports multiple digital and analog modulation schemes with frequency resolution to 0.1 Hz.
Technical Specifications
• Frequency Range: 20 Hz to 3.6 GHz
• Frequency Resolution: 0.1 Hz
• Frequency Accuracy: ± (frequency error + frequency reference error)
• RF Input Impedance: 50 Ohms
• RF Connector: N-type or equivalent
The FSMR3 offers variable analysis bandwidths tailored to different signal types. Sensitivity and dynamic range scale with resolution bandwidth and measurement configuration. Phase noise performance is specified for sensitive radio communications and radar applications. Amplitude accuracy defines measurement precision across the operating range.
