CALIBRATION 

 

 

Rev0305 

Calibration fixtures provide a means by which current probes can be calibrated to 

determine the insertion loss and transfer impedance factors for the probe.  Fixtures are also 
used when establishing or calibrating, drive levels for conducted susceptibility tests.  These 
applications are discussed in more detail in the following sections. 

The FCLCE-1000 Fixture is specifically designed for use with the CLCE-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 8 is the procedure to be followed for installing the CLCE-400 
Current Probe into the FCLCE-1000 Calibration Fixture.
