Advantages
- Non-intrusive coupling on harnesses without breaking the circuit.
- High power handling up to multi‑kilowatt CW on specific models.
- Broad frequency coverage with specialized UHF/SHF variants to 7 GHz.
- Standards-ready for DO‑160 Sec. 20/22, MIL‑STD‑461/462, ISO 11452‑4 and related procedures.
Key features
- Aperture choices from compact (⌀12 mm) to very large windows (up to 258 mm) for thick cable bundles.
- Cal fixtures matched to each probe family for fast setup and verification.
- Accessory ecosystem including dedicated high‑voltage variants.
