Featured EMC Product: Keysight FieldFox Handheld Microwave and RF Analyzers

Engineered for performance, portability, and precision, the Keysight FieldFox Handheld Microwave and RF Analyzer family delivers unmatched versatility for field and lab-based electromagnetic compatibility (EMC), RF, and microwave testing. Whether you are conducting pre-compliance EMI scans, verifying shielding integrity, measuring passive

components, or diagnosing interference in complex environments, FieldFox is designed to meet the demands of today’s RF engineers, EMC test professionals, and wireless field technicians.

Full Range of FieldFox Capabilities:

Keysight offers over 20 different FieldFox models, each tailored to unique measurement requirements and frequency ranges—from 4 GHz to 54 GHz. Each unit can be customized with modular software upgrades to consolidate multiple instruments into one. Available measurement capabilities include:

Vector Network Analyzer (VNA): Two-port S-parameter analysis for characterizing antennas, cables, filters, and passive components in EMC test chains.

Spectrum Analyzer: High-performance spectrum analysis with noise floor performance comparable to benchtop instruments—ideal for EMI and RF emissions diagnostics.

Cable and Antenna Tester (CAT): Return loss, distance-to-fault (DTF), and VSWR measurements to assess system integrity and cabling health.

Real-Time Spectrum Analysis (RTSA): Capture intermittent or time-varying RF signals with bandwidths up to 100 MHz, crucial for transient EMC events and signal hunting.

Over-the-Air (OTA) 5G Measurements: Evaluate 5G NR signals (FR1/FR2), mmWave deployments, and beamforming characteristics.

Power Meter & Signal Generator Capabilities: Add power measurements or CW/tone generation directly in the field, ideal for path loss testing and system calibration.

Rugged Construction Meets Lab-Grade Performance:

All FieldFox models are MIL-PRF-28800F Class 2 and IP53 certified, ensuring durability in harsh field conditions including temperature extremes, shock, and moisture. These instruments are fully operational in outdoor settings and vehicle-deployed environments—perfect for site EMI surveys, military EMC inspections, and on-site RF testing.

Key EMC & RF Applications:

Models of Note:

N991x Series: Compact, entry-level models for RF network analysis and cable testing (up to 26.5 GHz).

N995xA Series: High-frequency models up to 44 or 50 GHz for advanced mmWave and satellite testing.

N993xB Series: Ideal for spectrum and interference analysis with internal preamplifiers and dynamic range tailored for EMC diagnostics.

FieldFox Combination Units: Combine multiple tools (VNA + SA + CAT + RTSA) into one portable unit.

Why FieldFox for EMC Testing?

For test engineers needing to bridge the gap between the lab and field, FieldFox offers industry-leading dynamic range, phase noise, and sweep speed in a field-portable solution. It supports compliance to EMC standards such as CISPR, MIL-STD-461, DO-160, and FCC regulations when paired with appropriate accessories and probes. Additionally, FieldFox analyzers are compatible with Keysight’s PathWave Vector Signal Analysis (VSA) and 89600 software, enabling advanced demodulation and time-domain EMC analysis.
