1.0 Introduction
The ETS-Lindgren Current Probe is a clamp-on RF current transformer that
determines the intensity of RF current present in an electrical conductor or group
of conductors. The current probe is designed for use with electromagnetic
interference (EMI) test receivers or spectrum analyzers, or with any similar
instrument having a 50-ohm input impedance.
Model 93511 Series Current Probe
A current probe provides a way to accurately measure net (common mode) radio
frequency current flowing on a wire or bundle of wires without requiring a direct
connection to the conductor(s) of interest. The probe clamps around the test
conductor which becomes a one turn primary winding; the probe forms the core
and secondary winding of an RF transformer. Measurements can be made on
single-conductor and multi-conductor cables, grounding and bonding straps,
outer conductors of shielding conduits and coaxial cables, and so on.
