Equipment Setup to Measure RF Current
Standing waves can exist on the test conductor under test at or near
the resonant frequency. Under these conditions, several
measurements taken along the line will provide a complete picture of
the RF current distribution and amplitude.
F OR A S INGLE C ONDUCTOR
1. Place the probe jaws around the conductor so that the conductor
passes through the center opening.
2. Lock the jaws together.
F OR A T WO -C ONDUCTOR C ABLE
• To evaluate the common mode component of the noise current (the
net effect of the currents leaving and returning): Place the probe over
both conductors at the same time.
• To measure the interference current in either conductor separately:
Place the probe over each wire individually.
F OR M ULTI -C ONDUCTOR C ABLES
The probe will measure the net external effects of all the currents in the
conductors that pass through the center of the probe.
