The insertion loss of a current probe, at any given frequency, quantifies the
difference between the voltage quantity present on the center conductor
of the test fixture into which the probe is installed and the voltage quantity
present at the output connector of the probe.
To determine the insertion loss of the probe, a known voltage is applied into
one side of the calibration fixture, with the opposite side terminated into 50
ohms; while measuring the voltage present at the output of the probe. The
difference between the applied voltage and the measured voltage, at
any given frequency, is the insertion loss of the probe.
Shown in Figure 9 is the equivalent schematic circuit for the calibration. The
physical test setup showing the equipment and connections is illustrated in
Figure 10.
As measured in either of the circuits shown in Figure 9, the following
equation defines the insertion loss of the probe, at any given frequency:
NOTE:
Typical Insertion Loss Values for the CLCE-400 are represented in Figure 5
(Section 3.7).
