Rigol DNA6204 20 GHz 4-Port Vector Network Analyser

The Rigol DNA6204 provides a high-fidelity 4-port architecture for the comprehensive evaluation of transmission, reflection, and cross-talk characteristics. With a trace noise of 0.003 dB rms, the instrument delivers the measurement stability required for sensitive R&D and high-throughput automated semiconductor validation.

Covering a broad spectrum from 5 kHz to 20 GHz, the DNA6204 serves as a primary platform for analysing balanced components, differential interconnects, and MIMO antenna systems where phase-matched multi-port data is a technical requirement.

Mixed-Mode S-Parameter Characterisation 
The native 4-port configuration enables the direct extraction of mixed-mode S-parameters, allowing for the independent analysis of differential and common-mode performance. This capability is essential for characterising high-speed digital transmission lines, differential amplifiers, and balanced filters, effectively reducing measurement uncertainty by eliminating the need for external baluns or hardware transformations.

High Dynamic Range and Measurement Stability
The DNA6204 achieves a typical dynamic range of 127 dB (at 10 Hz IFBW), facilitating the characterisation of high-rejection devices and low-loss microwave networks with high precision. The ultra-low trace noise ensures high repeatability in magnitude and phase measurements, critical for meeting the performance benchmarks required in aerospace and telecommunications engineering.

True Device Performance via De-embedding
See the real performance of your DUT. The Fixture Removal and De-embedding features strip away errors caused by cables and adapters, delivering the true S-parameters you need.

Time-Domain Analysis and Fault Localisation
Integrated Time Domain Analysis (TDA) and Distance-to-Fault (DTF) functions allow for the localisation of impedance discontinuities and transmission line faults with millimetric resolution. Data is visualised via a 10.1-inch HD touch screen, supporting professional formats including Smith charts, polar plots, group delay, and VSWR for rigorous design verification and impedance matching.

ATE Integration and Error Correction
The DNA6204 supports comprehensive error correction via SOLT, OSL, and electronic calibration (ECal) protocols, ensuring traceable accuracy at the measurement plane. Designed for automated test environments, the instrument features full SCPI command set compatibility, LAN/USB/HDMI/GPIB interfaces, and Web Control for remote operation, facilitating seamless integration into existing automated test frameworks.

Technical Ecosystem and Compliance
The instrument is supported by an extensive range of RIGOL 26.5 GHz accessories, including phase-stable cables and mechanical calibration kits. Standardised SCPI support ensures code portability across the DNA series, allowing for a streamlined transition from 2-port to 4-port measurement environments while maintaining established engineering workflows and compliance standards.
