PMM RF-300 Triaxial Loop Antenna, BALUN, CDN, ISN, Lamp Simulator & Conical Metal Enclosure for Lighting EMC Testing

Overview

This suite of specialized accessories is engineered to support standardized electromagnetic compatibility (EMC) testing of lighting equipment—including luminaires, electronic ballasts, LED drivers, and dimming controllers—according to IEC/CISPR 15, EN 55015, CISPR 15:2018, and related harmonized standards. The system enables precise measurement of radiated and conducted emissions, as well as immunity evaluation under controlled laboratory conditions. Each component is calibrated and traceable to national metrology institutes (e.g., INRIM in Italy), ensuring compliance with ISO/IEC 17025 requirements for accredited EMC laboratories. The triaxial loop antenna (RF-300) operates on the principle of near-field magnetic field sensing, optimized for frequencies from 9 kHz to 30 MHz, while the conical metallic enclosure provides a reproducible, low-reflection test volume for lamp simulator characterization.

Key Features

• RF-300 Triaxial Loop Antenna: Three orthogonal, actively balanced loop sensors integrated into a single compact housing; enables simultaneous X/Y/Z magnetic field vector measurement without mechanical repositioning; built-in preamplifiers with 20 dB gain and noise floor < –120 dBm (1 Hz BW) at 10 MHz.
• High-Fidelity BALUN Transformer: 50 Ω unbalanced to 150 Ω balanced conversion with amplitude balance ≤ ±0.3 dB and phase balance ≤ ±2° across 150 kHz–30 MHz; designed to minimize common-mode current injection during radiated emission scans.
• Lamp Simulator Set: Covers incandescent (resistive load), fluorescent (inductive + capacitive ballast emulation), and LED driver (switch-mode power supply waveform replication); each unit features adjustable impedance profiles per IEC 61000-4-11 Annex B and CISPR 15 Annex D.
• Coupling/Decoupling Network (CDN): Compliant with CISPR 16-1-2 Ed. 4.0; supports AC mains ports up to 250 V / 16 A; incorporates transient suppression and galvanic isolation to protect EMI receivers during conducted emission testing.
• Impedance Stabilization Network (ISN): Designed for telecom/data line ports (e.g., DALI, 0–10 V, DMX512); maintains stable 150 Ω common-mode impedance from 150 kHz to 30 MHz per CISPR 16-1-2 requirements.
• V-Network & Conical Metallic Enclosure: V-network meets CISPR 16-1-2 specifications for asymmetric conducted emission measurements; conical shield offers ≥ 80 dB shielding effectiveness (30–200 MHz) and uniform field distribution for repeatable lamp EUT characterization.

Sample Compatibility & Compliance

The accessory set is validated for use with Class B lighting products per EN 55015, including retrofit LED lamps, integrated LED luminaires, emergency lighting systems, and smart lighting controllers. All components comply with CISPR 16-1-4 (antenna calibration), CISPR 16-1-2 (CDN/ISN performance), and IEC 61000-4-6 (conducted RF immunity test setup). Traceable calibration certificates are supplied with each RF-300 antenna and CDN unit. The lamp simulators are configured to replicate real-world load dynamics under voltage dips, interruptions, and harmonic distortion per IEC 61000-4-11 and IEC 61000-4-13, supporting full GLP-compliant test documentation workflows.

Software & Data Management

These hardware accessories integrate seamlessly with industry-standard EMC test software platforms—including Keysight PathWave EDA, Rohde & Schwarz EMV-Software, and Tektronix EMCVu—via IEEE-488 (GPIB), USB-TMC, or LAN (VXI-11). Raw antenna output signals are digitized using 16-bit ADCs synchronized to spectrum analyzer sweep clocks, enabling time-domain correlation of emission bursts with lamp switching events. Audit trails, calibration expiry alerts, and instrument configuration snapshots are automatically logged in accordance with FDA 21 CFR Part 11 and ISO/IEC 17025 data integrity requirements. All firmware updates are digitally signed and delivered through PMM’s secure customer portal.

Applications

• Pre-compliance and full compliance radiated/conducted emission testing of LED drivers per CISPR 15:2018 Clause 6 & 7
• Conducted RF immunity assessment of DALI gateways using ISN-based injection per IEC 61000-4-6
• Magnetic field profiling of high-frequency switching waveforms in constant-current LED modules
• Validation of EMC filter design efficacy using comparative lamp simulator + CDN measurements
• Reproduction of worst-case lamp load transients during surge and EFT testing (IEC 61000-4-4/5)
• Shielding effectiveness verification of luminaire enclosures via conical chamber + RF-300 scanning

FAQ

Are calibration certificates included with shipment?
Yes—each RF-300 antenna, CDN, and ISN unit ships with an ISO/IEC 17025-accredited calibration certificate issued by PMM’s in-house metrology lab (accredited by ACCREDIA, Italy).
Can the lamp simulator emulate PWM-dimmed LED loads?
Yes—the LED driver emulator supports adjustable PWM frequency (100 Hz–20 kHz), duty cycle (1–100%), and rise/fall times (50 ns–1 µs) to replicate real-world dimmer interactions.
Is the conical metal enclosure compatible with 1-meter and 3-meter measurement distances?
The enclosure is dimensionally optimized for 1-m distance measurements per CISPR 15 Annex F; optional field uniformity mapping reports are available for 3-m validation upon request.
Do these accessories meet MIL-STD-461G requirements?
While primarily designed for commercial lighting standards, the RF-300 antenna and CDN may be used in MIL-STD-461G CS114 and RS103 setups when paired with appropriate amplifiers and filters; formal qualification requires site-specific validation.
What is the maximum continuous input power rating for the CDN?
The standard AC mains CDN is rated for 16 A RMS continuous current at 250 VAC, 50/60 Hz, with thermal derating above 40 °C ambient per IEC 61000-4-6 Annex C.
