Rigol DSA800 Series Spectrum Analyzers for Advanced RF Testing and EMI Analysis

The Rigol DSA800 Series Spectrum Analyzers are advanced RF spectrum analyzers designed for RF testing, EMI pre-compliance testing, wireless communication analysis, signal integrity testing, and electronic product development. Built with powerful RF measurement technology, the DSA800 Series delivers high sensitivity, accurate signal analysis, and reliable spectrum monitoring for engineers, researchers, manufacturers, and educational laboratories.

These high-performance spectrum analyzers are widely used for RF troubleshooting, electromagnetic interference analysis, antenna testing, IoT device testing, communication system development, and production line testing.

Ultra-Low 10 Hz Resolution Bandwidth for Precise RF Signal Analysis

The Rigol DSA800 Series features an ultra-narrow Resolution Bandwidth (RBW) as low as 10 Hz, allowing engineers to accurately distinguish closely spaced RF signals with similar amplitudes. This advanced RF analysis capability improves signal resolution, enhances measurement accuracy, and provides detailed visibility into weak signals and adjacent channel interference.

The 10 Hz RBW capability is ideal for high-precision spectrum analysis, harmonic detection, low-noise signal measurements, and wireless communication testing.

Benefits of 10 Hz Resolution Bandwidth

• Improved RF signal discrimination
• Accurate adjacent signal analysis
• Enhanced weak signal detection
• Better low-noise spectrum analysis
• High-precision RF measurements

Exceptional Sensitivity with DANL as Low as -161 dBm

With the optional preamplifier enabled, the DSA800 Series achieves a Displayed Average Noise Level (DANL) as low as -161 dBm. This ultra-low noise floor allows users to detect extremely weak RF signals, hidden harmonics, low-level interference sources, and spurious emissions with greater accuracy.

The high sensitivity of the Rigol DSA800 Spectrum Analyzer improves RF troubleshooting performance and supports reliable signal analysis in both laboratory and production environments.

Advantages of Ultra-Low DANL

• Detect low-power RF signals easily
• Improve interference and harmonic analysis
• Enhance spectrum analyzer sensitivity
• Identify hidden RF noise sources
• Increase troubleshooting accuracy

EMI Pre-Compliance Testing for Faster Product Certification

The Rigol DSA800 Series supports EMI pre-compliance testing with built-in EMI filters, 6 dB filters, and quasi-peak detectors. These advanced EMI testing features help engineers identify electromagnetic interference issues during the product development stage, reducing costly compliance failures and accelerating product certification.

The integrated EMI software also supports automated EMI report generation for faster testing workflows and improved documentation.

EMI Pre-Compliance Features

• Conducted EMI testing
• Radiated EMI testing
• CISPR-compliant EMI filters
• Quasi-peak detector support
• Automated EMI diagnostics and reporting
• Faster EMI troubleshooting and compliance verification

Tracking Generator and VSWR Measurement Capability

The DSA800 Series “-TG” models include a built-in tracking generator for scalar network analysis and VSWR measurement applications. When used with a VSWR bridge, engineers can accurately measure Voltage Standing Wave Ratio for antennas, RF cables, amplifiers, filters, and communication systems.

This functionality makes the Rigol DSA800 Series ideal for RF component testing, impedance matching analysis, antenna tuning, and RF system maintenance.

VSWR Measurement Applications

• Antenna testing and tuning
• RF cable analysis
• Filter and amplifier testing
• Impedance matching verification
• RF network troubleshooting

Advanced UltraSpectrum Software for RF Signal Monitoring

The optional UltraSpectrum software enhances the performance of the DSA800 Series by providing advanced remote control, spectrum monitoring, waterfall display analysis, and RF signal visualization tools.

Engineers can perform detailed spectrum analysis, monitor real-time RF activity, and improve measurement efficiency using advanced display and analysis functions.

UltraSpectrum Software Features

• Remote spectrum analyzer control
• Real-time spectrum monitoring
• Waterfall spectrum display
• Advanced RF signal analysis
• Improved reporting and workflow efficiency
