The Rohde & Schwarz FSU8 is a high-performance spectrum analyzer covering a frequency range from 20 Hz to 8 GHz. It is engineered for demanding component design and production environments, featuring exceptional dynamic range, very low phase noise (-123 dBc/Hz at 10 kHz offset), and a high Third-Order Intercept (TOI) of typically +25 dBm. The instrument offers comprehensive analysis capabilities including resolution bandwidths up to 50 MHz, rapid ACP measurements in the time domain, and high-speed data acquisition up to 70 measurements per second.
