4.0 Using the CLCI-100 Probe with the FCLC-100 Fixture
Calibration fixtures provide a means by which current probes, including bulk current
injection (BCI) probes, can be calibrated to determine the transfer impedance,
insertion/coupling loss. Fixtures are also used to establish, or calibrate, power drive levels
into 50
Ω
or 150
Ω
systems for various conducted susceptibility/immunity tests performed
using BCI probes. These applications are discussed in more detail in the following
sections.
The FCLC-100 Fixture is specifically designed for use with the CLCI-100 BCI probe. The
intent of the fixture is to maintain the coaxial structure of the transmission line, while
allowing the probe to be installed around the center conductor of the coaxial line.
4.1 Installation of CLCI-100 Probe into FCLC-100 Fixture
Illustrated in Figure 5 is the procedure to be followed for installing the CLCI-100 BCI
Probe into the FCLC Calibration Fixture.
