Keysight N9913AU/361 EMI Measurements Option

Overview

Keysight's N9913AU/361 EMI Measurements option for FieldFox series analyzers measures and displays EMI signals to verify pre-compliance measurements before formal compliance testing. The option requires option 233 (Spectrum analyzer) and helps identify noise floor rise, interference patterns, and regulatory compliance issues in devices and networks.

Key Features

• Amplitude Probability Distribution (APD) Statistics
• Resolution bandwidths: 200 Hz, 9 kHz, 120 kHz (6 dB), and 1 MHz impulse bandwidth, auto-coupled to CISPR bands
• Detector modes: Quasi-Peak, EMI Average, Positive Peak
• Identifies noise floor rise and interference from equipment
• Performs equipment and network regulatory audits against CISPR 16-1-1 and other standards

Applications

• Pre-compliance EMI testing and verification
• Troubleshooting circuit board electromagnetic issues
• Equipment and network regulatory audits
• System-level performance impact analysis due to EMI degradation
