Tektronix 119-4146-00 Near-Field Probe Set

Overview

The Tektronix 119-4146-00 is a comprehensive near-field probe set designed for diagnostic testing of radiated emissions. The kit includes three magnetic field probes, two electric field probes, and a custom carrying case with extension handle for convenient operation. It provides versatile coverage for EMI troubleshooting across a broad frequency range.

Key Features

• Three (3) magnetic field (H-field) probes: 6 cm, 3 cm, and 1 cm loop designs
• Two (2) electric field (E-field) probes: 3.6 cm ball and stub designs
• Frequency Range: below 100 kHz to above 1 GHz
• 50 Ω impedance for all probes
• 20 cm extension handle for safe operator distance
• Custom carrying case with protective foam

Probe Types and Characteristics

• H-Field Probes: Figure-8 response pattern with primary pickup broadside to the loop; more susceptible to repeatable measurements; immune to capacitive coupling effects
• E-Field Probes: Essentially omnidirectional response; susceptible to capacitive coupling with external objects but reject magnetic field components

Applications

• EMI/RFI source identification and localization
• Pre- and post-remediation emissions testing
• Field strength mapping and signal characterization
• Broadband radiated emissions diagnostics
