The Rohde & Schwarz R&S®FSH4 is a compact, high-performance handheld spectrum analyzer designed for field testing, on-site maintenance, and mobile measurement scenarios. It masterfully balances portability with professional-grade functionality, making it the ideal solution for telecom, broadcasting, aerospace, and industrial electronics applications.
Frequency Range: 9 kHz to 4 GHz (covering key bands for cellular communication, Wi-Fi, Bluetooth, and industrial radio systems).
Sensitivity: Typical -130 dBm (at 1 GHz, 10 kHz resolution bandwidth/RBW, preamplifier on) for capturing weak signals in noisy environments.
Resolution Bandwidth (RBW): 1 Hz to 1 MHz (manual or automatic), supporting precise analysis of both narrowband and wideband signals.
Spectrum Analysis: Real-time display with sweep times from 10 µs to 100 s and multiple trace modes (max hold, min hold, average).
Power Measurement: Integrated peak, average, and channel power functions compliant with telecom standards like LTE/5G NR.
Distortion Testing: Measures harmonic distortion, spurious emissions, and adjacent channel leakage ratio (ACLR).
Vector Network Analysis: Optional 2-port VNA capabilities (with R&S®FSH-Z10) for reflection and transmission measurements.
Rugged Design: IP54-rated enclosure protecting against dust and water splash. Complies with MIL-STD-810H standards for shock and vibration resistance.
Compact Form Factor: Dimensions of 240 mm × 130 mm × 65 mm and lightweight at only ~1.5 kg (including battery).
Battery Power: Up to 4 hours of continuous operation using a rechargeable lithium-ion battery.
The analyzer features a 5.7-inch color touchscreen (640 × 480 pixels) with intuitive menus and tactile hardware keys, allowing ease of use even when operating with gloved hands. Connectivity is supported via USB 2.0 and LAN (LXI-compliant) for swift data transfers and remote operation, alongside optional Bluetooth support.
