Frequently Asked Questions

Q: What are near-field magnetic field probes used for in electronics testing?

A: Near-field magnetic field probes are used to detect and locate sources of electromagnetic interference (EMI) on PCBs and within electronic components. They are essential tools for EMI/EMC troubleshooting, allowing engineers and technicians to identify problem areas before formal compliance testing.

Q: What connector type do these near-field probes use?

A: These probes feature an SMA female connector, which is a standard RF connector widely compatible with spectrum analyzers, oscilloscopes, and low-noise preamplifiers used in EMI and RF testing setups.

Q: Can these probes be used with a preamplifier or spectrum analyzer?

A: Yes! These near-field magnetic probes are fully compatible with low-noise preamplifiers and spectrum analyzers. Pairing them with a preamplifier enhances sensitivity, allowing you to measure weaker phase noise and spectrum components with greater accuracy.

Q: How many probes are included in this set, and why do I need multiple?

A: The set includes 6 near-field magnetic field probes. Having multiple probes allows you to cover different loop sizes and orientations, compare measurements across different board areas simultaneously, and always have spares available for replacement — maximizing efficiency in your testing workflow.
