The manual describes features, specifications, operation, and accessories of the lightweight, compact Rohde & Schwarz FSL spectrum analyzer.
The Rohde & Schwarz FSL is a lightweight (<8 kg) and compact spectrum analyzer covering a continuous frequency range from 9 kHz to 18 GHz with a 28 MHz I/Q demodulation bandwidth. It offers high‑performance RF characteristics, fast scan speeds (>80 scans /s), and optional built‑in battery operation for portable use.
The instrument supports remote control via LAN or IEC/IEEE bus using SCPI commands, and a wide variety of optional modules (e.g., additional interfaces, power‑probe adapters, and tracking sources) can be added without opening the chassis. Detailed specifications, ordering information, and recommended accessories are provided in the later sections. This manual is written in Chinese.
