- CALIB RATION
Rev081219
Calibration fixtures provide a means by which current probes, including bulk current
injection (BCI) probes, can be calibrated to determine the insertion loss and transfer
impedance factors for the probe. Fixtures are also used to establish, or calibrate, drive
levels for conducted susceptibility tests performed using BCI probes. These applications
are discussed in more detail in the following sections.
The FCLC-400 Fixture is specifically designed for use with the CLCI-400. 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.
Illustrated in Figure 10 is the procedure to be followed for installing the CLCI-400 BCI
Probe into the FCLC-400 Calibration Fixture.
