Rohde & Schwarz FSH-Z44 Directional RF Power Sensor 200MHz–4GHz Forward and Reverse RF Power Measurement, Compatible with FSH Analyzers

Directional RF Power Measurement for FSH Series Analyzers

The Rohde & Schwarz FSH-Z44 is a directional RF power sensor designed for accurate forward and reverse power measurement from 200 MHz to 4 GHz. It enhances the capability of compatible Rohde & Schwarz handheld spectrum analyzers—including the FSH4, FSH6, and FSH8 models—by enabling real-time verification of transmitter output, antenna loading, and feedline performance during field deployment. The sensor integrates directly with the FSH power-sensor interface, ensuring fast setup and reliable results on site.

Why It Helps

• Provides forward and reverse RF power measurement to evaluate antenna matching and system health.
• Supports the transmitter power levels commonly encountered in routine installation and service work.
• Helps isolate feedline faults, poor antenna connections, or mismatches that degrade system performance.
• Compact and rugged with an integrated sensor cable for straightforward field use.

Key Highlights

• 200 MHz–4 GHz directional RF power sensing for broadcast, land-mobile, and wireless bands.
• 30 mW to 120 W average measurement range and up to 300 W peak envelope power.
• Forward and reverse measurement for on-site antenna and feedline assessment.
• Designed for use with Rohde & Schwarz FSH-series handheld analyzers, including FSH4, FSH6, and FSH8.

Applications

• Transmitter output power verification.
• Antenna and cable system performance checks.
• Field diagnostics for public-safety, commercial, and broadcast RF installations.
