The Rohde & Schwarz FSWP provides high‑sensitivity phase‑noise and AM‑noise measurements for radar, OCXO, DRO and VCO development.
The FSWP combines an ultra‑low‑noise internal source with cross‑correlation to achieve exceptional phase‑noise sensitivity, allowing fast measurements of high‑stability sources such as radar oscillators. It integrates signal‑and‑spectrum analysis, pulse‑source phase‑noise measurement, and optional add‑on modules for extended functionality.
The manual describes system setup, measurement procedures, optional hardware (B‑ and K‑options), technical specifications, ordering information, and service details, enabling users to configure the instrument for a wide range of frequency‑synthesis and VCO testing applications. This manual is written in Chinese.
| Frequency range | 1 MHz ~ 8 GHz / 26.5 GHz / 50 GHz |
|---|---|
| Typical phase‑noise at 1 GHz | -172 dBc (1 Hz) |
| Low‑noise floor (D ANL) | -156 dBm (1 Hz) |
| Measurement uncertainty | < 0.2 dB below 3.6 GHz, < 0.3 dB below 8 GHz |
| Signal analysis bandwidth | 80 MHz |
By installing the FSWP‑K4 option, the instrument provides one‑click pulse‑source phase‑noise measurement and automatic pulse‑parameter extraction.
Yes, the B1 option adds integrated signal‑and‑spectrum analysis functionality to the FSWP.
The typical phase‑noise value is about –140 dBc (1 Hz) for a 1 GHz carrier.
