Magnetic Field Testing on High-Frequency Connectors for PIM Quality Control
Magnetic contamination can cause PIM and signal degradation. Magnetic field testing reliably identifies critical connectors before installation.
The challenge
In modern 4G and 5G networks, passive intermodulation (PIM) can degrade signal quality. Magnetic contamination or ferromagnetic materials in high-frequency connectors contribute to non-linear mixing effects. Since PIM cannot be filtered out, components must be verified before installation. Reliable residual magnetic field testing is therefore essential for quality control.
The solution
Magnetic signature testing is performed using MAGNETOSCOP or MAGNETOMAT systems with a differential probe such as the PFD-100. The opposing sensor arrangement compensates for environmental disturbances while detecting local magnetic anomalies. Components are positioned on one sensor, enabling rapid classification of magnetic field strength without magnetic shielding.
The result
The method enables clear differentiation between compliant and non-compliant connectors, for example ~100 nT for acceptable parts and ≥1000 nT for defective ones. High sensitivity and differential measurement improve reproducibility and detection reliability. The system supports effective PIM quality control in high-frequency electronic components.
