The Rohde & Schwarz LDS is a signal generator engineered for precision signal generation across demanding research, development, and testing applications. Built on Rohde & Schwarz’s foundation of innovation and reliability, it delivers the frequency coverage, output power, and signal fidelity required in modern RF and microwave test environments.
Technical Specifications
Frequency Coverage
Signal generation capability extends across broad frequency ranges. Vector and analog signal generator variants within the Rohde & Schwarz portfolio cover spans from 100 kHz to 44 GHz, 9 kHz to 12.75 GHz, and up to 70 GHz depending on configuration.
Output Power
Standard output power reaches +18 dBm to +25 dBm, with select configurations delivering up to +38 dBm.
Signal Quality
Phase noise performance achieves SSB values below -120 dBc (typ.) at 10 GHz with 20 kHz offset. Close-in SSB phase noise measures -83 dBc (typ.) at 10 GHz with 10 Hz offset. Non-harmonic signal components remain below -90 dBc (typ.) at 10 GHz.
Modulation Bandwidth
Internal RF modulation bandwidth reaches 1 GHz on select models.
