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 50Ωor 150Ωsystems 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.

4.2 Insertion Loss/Coupling Factor Measurement
Illustrated in Figures 6 and 7 are typical setups for the measurement of a current
probe’s insertion loss, also known as coupling factor. Figure 6 shows the setup for
a 50 ohm system (100 ohm loop); and Figure 7 shows the setup for a 150 ohm
system (300 ohm loop).
The insertion loss/coupling factor is essentially the difference between the voltage
present on the conductor(s) passing through the current probe aperture and the
voltage present at the output of the probe. These two quantities are depicted as
V1and V2, respectively, in Figure 8; where V2 - V1= Insertion Loss/Coupling Factor.

4.3 Transfer Impedance Factors
When performing current measurements, the conductor(s) under test are passed
through the aperture of the current probe. The RF port of the current probe is
connected to the 50 ohm RF input of a spectrum analyzer or EMI receiver, where
a voltage value is measured.
The transfer impedance factor includes the loss of the probe (see section 4.2),
and also converts the measured voltage value to a current value corresponding
to the current flowing on the conductor(s) under test.
Illustrated in Figure 8 is a diagram of the equivalent calibration circuit, along with
the associated calculations.

4.4 Conducted Immunity Test Level Calibration (IEC 61000-4-6)
Calibration of test levels per IEC 61000-4-6 is performed with the CLCI-100 Bulk
Current Injection Probe installed in the FCLC-100 Calibration Fixture. The
calibration is performed into a 150 ohm system, rather than the standard 50 ohm
system employed by other standards, such as Mil-Std 461 and RTCA DO-160.
To realize a 150 ohm system, ADA-515-2 150Ωto 50ΩAdapters are installed on
either side of the test fixture.
4.4.1 Test Generator Equipment (Method A vs Method B)
Per the IEC 61000-4-6 standard, there are two acceptable procedures for
quantifying the Test Generator power when the appropriate test level is
measured during the calibration at any given frequency, so that the same
level can be reproduced during the actual testing process. For the
purposes of this procedure, we will refer to these as METHOD A (Signal
Generator Output Method) and METHOD B (Forward Power Method).
Illustrated in Figure 9 are example diagrams of the respective test
generator systems.
FIGURE 9 - Examples of Test Generator Systems
For each method, the RF power is injected into RF port of the bulk current
injection probe, and the amplitude is measured at the output of the 150Ω
to 50ΩAdapter (ADA-515-2) connected to one side of the test fixture
(through a power attenuator). For each test frequency, the amplitude of
the injected RF is adjusted incrementally until the measured amplitude
reaches the appropriate level (Umr).

Method A: For method A, once the appropriate amplitude is
measured during calibration process, the signal
generator output level is recorded with respect to the
test frequency.
During the test, the signal generator output level at any
given test frequency is equal to the respective signal
generator output level recorded during the calibration.
Method B: For method B, once the appropriate amplitude is
measured during the calibration process, the forward
power of the test generator is recorded. The forward
power is measured with an RF power meter and power
sensor, typically connected to the forward port of a
directional coupler installed in series with the RF output
of the power amplifier.
During the test, the signal generator output level is
adjusted so that the forward power measured on the
power meter at any given frequency is equal to the
respective forward power level recorded during the
calibration.
In the following sections, instructions are included for both methods:
Instructions common for both METHOD A and METHOD B are shown in
BLACK text.
Any instructions which apply only for METHOD A are shown in GREEN text.
Any instructions which apply only for METHOD B are shown in BLUE text.

4.4.2 Calibration-related Calculations
The following sets of calculations are indispensible to the proper
application of the calibration process. These calculations apply only to
calibrations performed per the IEC 61000-4-6 standard. Please refer to
the IEC 61000-4-6 standard for further information.
4.4.2.1 Test Level Calculations
Prior to the start of the calibration process, (Umr)must be
calculated. (Umr)represents the voltage to be measured at the
output of the ADA-515-2 150Ωto 50ΩAdapter connected to
one side of the test fixture, and must not be confused with the
open circuit test level (Uo)for the calibration (i.e.: 1 Vrms, 3
Vrms, 10 Vrms, etc.) The relationship between (Umr)and (Uo)is
given below:
So, for instance, if calibration is being performed for a test level
of 10 Vrms:
Due to the fact that, in our example, there is a 30 dB attenuator
between the output of the 150Ωto 50ΩAdapter and the input
of the spectrum analyzer, the (Umr)value must also be
corrected for the attenuation.
NOTE: Attenuators other than 30 dB may also be used, assuming
that any corrections will be adjusted accordingly.

4.4.2.2 Test Level Offset Calculations
If the CLCI-100 Bulk Current Injection Probe will be used for
multiple test levels (1 Vrms, 3 Vrms, 10 Vrms, etc.), calibration
should be performed at the highest test level. Calibration data
for the lower test levels can then be calculated as shown
below:
The offset factor calculated above can then be applied to the
calibration data as shown below:
4.4.2.3 Test Frequency Calculations
The frequency range of the test is, in most cases, 150 kHz to 80
MHz; and, in some cases, 150 kHz to 230 MHz. The calibration
and test is performed at discrete, logarithmically spaced
frequencies (as opposed to a frequency sweep). The
logarithmic spacing of the test frequencies means that the
actual step size increases after each step. The maximum step
size at any given frequency is equal to 1% of the present
frequency. Below is a truncated example of the test
frequencies, showing the respective step sizes.
Step Size = Present Frequency * 0.01
Next Test Frequency = Present Frequency + (Present Frequency * 0.01)

4.4.3 Equipment Setup
On a conductive ground plane, connect the FCLC-100 Calibration Fixture
with the CLCI-100 Bulk Current Injection Probe installed to the Calibration
Accessories, Adapters and Attenuators as shown in Figures 10. The
bottom surface of test fixture should be flush against the top surface of the
ground plane, and should either be: bolted directly to the ground plane
(through their respective mounting holes); or should be bonded to the
ground plane using copper tape with conducted adhesive (3M #1181 HD
recommended).
