INTRODUCTION
The ETS-Lindgren EMCO brand Model 94456 RF Current
Probe is a clamp-on RF current transformer designed for
use with Electromagnetic Interference (EMI) Test
Receivers/Spectrum Analyzers, or with any similar
instrument having a 50 Ohm input impedance, to determine
the intensity of RF current present in an electrical
conductor or group of conductors.
The Current Probe provides a means of accurately
measuring 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 Model
94456 Current Probe is simply clamped around the test
conductor which then becomes a one turn primary winding,
with the current probe forming the core and secondary
winding of an RF transformer. Measurements can be made
on single and multi-conductor cables, grounding and
bonding straps, outer conductors of shielding conduits and
coaxial cables, etc.
