Electromagnetic Compatibility (EMC/EMI) Pre-Compliance Testing

Xin Tester Near Field Probe Kit (9KHz – 3GHz EMC Diagnostic Set)

Failing official EMC radiation compliance chamber tests causes costly product launch delays and redesign cycles. The Xin Tester 4-piece near field probe kit enables engineers to isolate electromagnetic radiation hot-spots directly on circuit boards before heading to compliance labs. By detecting magnetic field loops and electric field traces across 9kHz to 3GHz, it pinpoints offending clock lines, switching inductors, and IC packages. Explore our complete selections in the Accessories catalog.

H-Field vs E-Field Isolation

Large loop probes provide high sensitivity for sweeping broad PCB areas; smaller loop probes narrow down specific traces; the vertical E-field tip isolates high-voltage RF potentials on floating heat sinks and transformer shields.

Shielded Multi-Layer Design

Constructed with multi-layer FR4 boards where outer ground planes suppress common-mode electric field pick-up, ensuring that magnetic loop probes respond primarily to true circulating RF currents.

Package Inclusions

Kit contains 3× H-Field probes (large, medium, small), 1× E-Field probe, 1× SMA-male to SMA-male coaxial cable, 1× SMA to BNC adapter, and a protective EVA hard carry case.

FAQs

Q1: What is the difference between magnetic and electric field probes?

A1: Magnetic (H-field) probes detect the magnetic component of electromagnetic emissions, ideal for low-frequency and conducted EMI. Electric (E-field) probes detect the electric component, useful for surface and wire-level high-frequency field measurements.

Q2: Why would I need the 30dB amplifier?

A2: The optional 30dB pre-amplifier boosts weak probe signals above the noise floor of your spectrum analyzer, dramatically improving measurement sensitivity for low-emission DUTs and allowing accurate readings in low-signal environments.

Q3: Which probe size should I use for PCB testing?

A3: For PCB trace-level emissions, the HNFP-4 with 2mm loop diameter is ideal. For larger components or bus structures, the HNFP-3 (5mm) or HNFP-2 (10mm) work better. The HNFP-1 (25mm) is best for general bulk radiation testing.

Q4: Can I buy individual probes separately?

A4: This product is sold as pre-configured bundles to provide complete testing coverage at a value price. For individual probe purchases, please contact us directly.
