The Rohde & Schwarz FSV40 is a signal and spectrum analyzer delivering 10 Hz to 40 GHz frequency coverage with analysis bandwidth up to 160 MHz. Built for RF development, production, and service environments, it combines high-speed measurement capability with 0.01 Hz frequency resolution and 0.4 dB level measurement uncertainty to 7 GHz. The instrument executes phase noise, noise figure, vector signal analysis, analog demodulation, and EMI diagnostics across configurable sweep architectures—from 101 to 32,001 trace points. Its touchscreen interface enables rapid operation, while optional frequency stability upgrades—including OCXO and ultra-high precision references with aging rates to 4 × 10⁻⁹/year—support metrology-grade applications. The FSV40 extends beyond 40 GHz via harmonic mixer options, reaching 110 GHz.
