Handheld and Field-Ready Analyzers
For field measurements, interference hunting, and installation tasks, Rohde & Schwarz provides the handheld Rohde & Schwarz FSH and Rohde & Schwarz FPH (Spectrum Rider) series. Lightweight models like the Rohde & Schwarz FSH3 and Rohde & Schwarz FSH18 weigh only 2.5 kg, facilitating portable operations. While early models like the Rohde & Schwarz FSH3 cover up to 3 GHz, newer handheld developments like the Rohde & Schwarz FPH offer base models that can be upgraded up to 44 GHz.\n\nField units are equipped with optimized power systems; for example, the Rohde & Schwarz FSH4 and Rohde & Schwarz FSH8 operate on rechargeable Li-ion batteries, whereas the Rohde & Schwarz FSH3 utilizes an internal NiMH battery. Some field variants, such as the Rohde & Schwarz FSH8 version .28, integrate internal VSWR bridges and tracking generators for comprehensive cable and antenna testing.
Compact and General-Purpose Benchtop Analyzers
When benchtop capability is required in a portable or space-constrained form factor, the Rohde & Schwarz FSL and Rohde & Schwarz FSL6 serve as ideal options. Weighing 7 kg without batteries, the FSL series integrates standard signal analysis capabilities, with the FSL and FSL6 featuring a 28 MHz analysis bandwidth.\n\nFor more demanding development and manufacturing environments, the Rohde & Schwarz FSP3 and Rohde & Schwarz FSP7 focus on highly accurate, general-purpose measurements, boasting a total measurement uncertainty of just 0.5 dB. The Rohde & Schwarz FSP3 spans from 9 kHz to 3 GHz, while the Rohde & Schwarz FSP7 expands coverage to 7 GHz.
High-Speed Analysis and Signal Demodulation
The mid-range FSV family, including the Rohde & Schwarz FSV7, Rohde & Schwarz FSV13, Rohde & Schwarz FSV30, and Rohde & Schwarz FSV40, is tailored for high-speed signal processing and touchscreen-based operation. These models feature a standard 40 MHz analysis bandwidth, which on the Rohde & Schwarz FSV30 can be expanded up to 160 MHz via options. This family spans a wide range of frequencies, from the 7 GHz limit of the Rohde & Schwarz FSV7 up to 40 GHz on the Rohde & Schwarz FSV40.\n\nFor specialized communication applications, the Rohde & Schwarz FSQ8 merges high-end spectrum analysis with vector signal analysis up to 8 GHz, delivering low phase noise of -123 dBc/Hz at a 10 kHz offset.
High-End Laboratory and Microwave Analyzers
For ultra-wide dynamic range, low phase noise, and laboratory-grade measurements, Rohde & Schwarz offers the classic FSE series and the ultra-high-performance FSU series. The FSE series includes the Rohde & Schwarz FSEA20 (9 kHz to 3.5 GHz), the Rohde & Schwarz FSEA30 (20 Hz to 3.5 GHz), the Rohde & Schwarz FSEB30 (20 Hz to 7 GHz), and the microwave-focused Rohde & Schwarz FSEM30 (20 Hz to 26.5 GHz).\n\nFor absolute performance in phase noise and dynamic range up to microwave and millimeter-wave frequencies, the FSU series is standard. The Rohde & Schwarz FSU8 covers up to 8 GHz, the Rohde & Schwarz FSU46 reaches up to 46 GHz, and the Rohde & Schwarz FSU50 extends to 50 GHz, offering an attenuator range from 0 to 75 dB in 5 dB steps.
