- Typical recommendation: every 12 months under most quality systems (annual calibration).
- Depending on your quality policy, usage severity, and required measurement uncertainty, intervals of 12–24 months are common. After repair or significant mechanical/electrical stress, recalibration should be performed regardless of interval.

Quick Overview
- What it is: Passive near-field (close-field) probe, 9 kHz–30 MHz, for EMI/EMC troubleshooting with spectrum analyzers/EMI receivers.
- Typical use: Localizing low-frequency emission sources on PCBs, cables, and enclosures; pre-compliance checks; diagnosing SMPS and wiring harness noise.
- Status: Obsolete (out of production, no longer supported by the OEM); commonly available used/refurbished.
A Keysight (Agilent/HP) 11941A Close-Field Probe, 9 kHz to 30 MHz doesn’t lie—but it will expose lazy calibration. High‑accuracy measurements demand calibration performed by technicians who understand the 11941A, the specification limits, and the standards behind them.
Expert calibration verifies performance against traceable references, flags drift before it becomes failure and documents every adjustment. This isn’t box‑checking or sticker‑slapping. Its precision enforced. If your work depends on numbers you can defend, Rogue Calibration helps find the right calibration service provider for you.
