The Rohde & Schwarz FSUP26 is a premium signal source analyzer and high-end spectrum analyzer with a frequency range up to 26.5 GHz. Designed for complete characterization of oscillators and high-performance phase noise measurements, it combines the capabilities of a phase noise tester, transient recorder, and a spectrum analyzer in a single cabinet. It features dual ultra-low noise DC ports for tuning and supply voltages.
