Rohde & Schwarz FSP30 9KHz-30GHz Spectrum Analyzer

The Rohde & Schwarz FSP30 is a spectrum analyzer covering 9 kHz to 30 GHz for signal analysis, interference detection, and component testing in development and production environments. This instrument delivers measurement uncertainty of 0.5 dB and displayed average noise level of typically -155 dBm (1 Hz) without preamplifier, making it suitable for precision RF characterization across multiple domains.
