Electro-Metrics EFP-30 Electrostatic Field Probe Instruction Manual
The Electro-Metrics Model EFP-30 is a handheld, uncalibrated electrostatic field probe designed to investigate sources of localized electric field radiation. It operates within a frequency range of 9 kHz to 1 GHz and is intended for searching for Radio Frequency (RF) leakage. The probe helps users determine the side of an article under test that is radiating the highest RF level before running MIL-STD or FCC radiated emissions tests.
The device features a 50Ω nominal impedance and connects via a TNC output connector. Mechanically, it measures 280 mm in length with a diameter of 32 mm and weighs 454 g. The manual includes information on the product description, technical specifications, and a limited 12-month warranty covering defects in materials and workmanship.
