Specification

The ROHDE & SCHWARZ FSW26 Signal & Spectrum Analyzer sets the benchmark for high-performance RF analysis, combining an extensive frequency range with unparalleled measurement accuracy. With a DC-coupled bandwidth from 2 Hz to 26.5 GHz and AC-coupled operation from 10 MHz to 26.5 GHz, this instrument is perfectly suited for demanding applications such as wideband modulation analysis, harmonic measurements, and phase noise testing. Its 0.01 Hz frequency resolution allows for precise signal characterization, while the internal reference oscillator delivers exceptional long-term stability with an aging rate of ±1×10⁻⁷ per year and a calibration accuracy of ±1×10⁻⁸. Designed for both laboratory and field use, the FSW26 ensures reliable, repeatable results across the entire frequency spectrum.
