Rigol RSA808 5kHz – 8.5GHz Real Time Spectrum Analyser with Tracking Generator
The Rigol RSA808 is a compact, portable 8.5 GHz real-time spectrum analyser designed for RF research and development, manufacturing, and field testing.
- Frequency Range: 5 kHz to 8.5 GHz
- Real-Time Bandwidth: Up to 40 MHz max bandwidth with 199,804 frames/s FFT rate
- Tracking Generator as standard
- Signal Capture Performance: 100% POI down to 5.62 μs minimum signal duration
- RF Sensitivity (DANL): -168" dBm" (typical, preamplifier on
- Phase Noise: -112" dBc/Hz" @ 10 kHz offset (1 GHz carrier, typical)
- Display: 7-inch HD (1024×600) capacitive multi-touch interface
- 5 Modes: RTSA, GPSA, VSA, EMI & ADM
Multi-Mode Measurements
The RSA808 operates across 5 distinct working modes to address varied RF testing topologies. GPSA and RTSA come as standard configurations. Optional software applications include VSA, EMI Pre-compliance, Analog Demodulation (ADM), and Phase Noise Measurements.
Powerful Characterisation and Modulation Analysis
When expanded with VSA and ADM software options, the RSA800 serves as a flexible digital and analogue demodulation platform. It supports deep error vector magnitude (EVM) analysis across various modulation schemes like QAM, PSK, and FSK, keeping residual QPSK EVM below 1.0% at 1 Msps. Built-in CISPR filters and detectors further streamline rapid EMI pre-compliance routines.
Modern Portable Form Factor and Native Connectivity
Weighing just 1.9 kg, the RSA800 features a compact footprint optimised for the lab bench, production line, or field testing. The unit pairs a 7-inch touch display with LXI-compliant Gigabit LAN, USB, and HDMI connectivity for seamless automated control and remote monitoring, either via SCPI or the built-in web interface. Type-C PD power input allows operators to run the complete architecture via mobile power banks.
