RIGOL RSA804 REAL-TIME SPECTRUM ANALYZER

Overview

The RIGOL RSA804 Real-Time Spectrum Analyzer is expertly engineered to meet professional RF testing demands across wireless communications, IoT, automotive electronics, and laboratory environments. Utilizing RIGOL's custom-engineered hardware platform, this 4.5 GHz instrument delivers an exceptional measurement experience tailored for complex signal analysis, transient interference hunting, and high-precision debugging without compromising on test speed or accuracy.

Built for both stationary lab integration and dynamic field testing, the RSA804 combines a wide 5 kHz to 4.5 GHz frequency range with a maximum 40 MHz real-time analysis bandwidth. Highly integrated and weighing only 1.9 kg, its compact form factor and native Type-C power bank compatibility make it uniquely adapted for mobile operations and field deployments where traditional AC power is unavailable. With standard General-Purpose Spectrum Analysis (GPSA) and Real-Time Spectrum Analysis (RTSA) modes, the RSA804 ensures engineers can instantly isolate intermittent anomalies and gain actionable, deep signal insights.

Product Features

Professional Real-Time Performance

With a maximum 40 MHz real-time bandwidth and an outstanding FFT rate of up to 199,804 frames per second, the RSA804 excels at capturing transient, fast-hopping, or intermittent signals that traditional swept spectrum analyzers miss completely, achieving a 100% Probability of Intercept (POI) for signals down to 5.62 microseconds.

Multi-Mode Flexibility & Expandability

The architecture supports five distinct working modes to adapt to diverse testing criteria, providing comprehensive spectrum analysis, real-time capture, and vector signal validation to smoothly accelerate your workflow from basic signal observation to complex domain analysis.

Custom-Engineered Portability

Weighing a mere 1.9 kg with an ultra-slim depth of 77.38 mm, the RSA804 is an agile field asset. Its low-power design runs directly from a standard Type-C adapter or standard portable power bank, ensuring seamless field maintenance and drive-test capabilities without bulky equipment.

Advanced Built-in Tools

The instrument features a built-in tracking generator as standard, allowing for immediate scalar network analysis such as component, filter, and cable measurements. Signal visualization is optimized on a 7-inch capacitive multi-touch screen showing multi-pane windowed layouts for fast data correlation.
