NSIL Chamber Validation: Low-Frequency EMC Testing

Shielding Integrity Services provides expert NSIL Chamber Validation to confirm your Semi-Anechoic Chamber (SAC) meets the essential performance criteria required for compliant low-frequency radiated emissions testing. This critical evaluation guarantees your chamber provides accurate and reliable data in the 9 kHz to 30 MHz range, adhering strictly to official standards.

Test Purpose & Standards

The Normalized Site Insertion Loss (NSIL) test confirms your Semi-Anechoic Chamber (SAC) meets the essential performance criteria required for compliant low-frequency radiated emissions testing.

Accreditation Standard

• CISPR 16-1-4 (The specific edition and year will be noted in your report.)

Technical Specifications & Methodology

The NSIL measurement is a test involving magnetic field measurements inside the chamber.

Frequency & Range

• Frequency Range: 9 kHz – 30 MHz (Critical for low-frequency emissions).
• Test Distance: Performed at 3-meters.

Measurement Methodology

Our NSIL measurement is an adaptation of the NSA procedure, using specialized H-field (magnetic field) loop antennas. Performance is demonstrated using loop antennas in three orthogonal orientations: Hx, Hy, and Hz.
