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 50Ω or 150Ω 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.

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
and 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 150Ω to 50Ω Adapters 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.

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 50Ω Adapter (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 (U
mr
).

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. (U

one side of the test fixture, and must not be confused with the
open circuit test level (U

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

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)

4.4.4 Level Setting Process
1) With the calibration test setup configured as shown in Figure 11 or
Figure 12, set the frequency of the signal generator to 150 kHz (without
modulation).
2) WITHOUT exceeding [the 1 dB gain compression point of the power
amplifier minus 5.1 dB], adjust the amplitude setting of the signal
generator until the amplitude measured on the spectrum analyzer is
equal to the (U
test level (U
) for which calibration is being performed (see section
o
4.4.2.1).
3) Record either:
(a) the frequency (fx) and amplitude setting of the signal generator
(SGout)
-or-
(b) the frequency (fx) and forward power measured using the power
meter/sensor (FWDpwr).

4) Increase the frequency by a maximum of 1% of the present frequency
(see section 4.4.2.3).
5) Repeat steps (2) through (4) until the next frequency in the sequence
would exceed the highest frequency of the test. For tests up to 80
MHz, there should be at least 633 test frequencies; and for tests up to
230 MHz, there should be at least 739 test frequencies.

4.4.6 Running the Test
Examples of the test setup are shown in Figure 13 (for METHOD A) and
Figure 14 (for METHOD B).
The same Test Generator equipment used for the calibration is used to
inject the RF energy onto the EUT lines under test via the CLCI-100 Bulk
Current Injection probe. The calibration data table is used to set the
signal generator output at any given frequency to either:
a) the respective SGout value determined during calibration for the
present test frequency; or,
-or-
b) the level at which the power indicated by the power meter is
equal to the respective FWDpwr value determined during
calibration for the present test frequency.
Typically, the test is performed from the lowest test frequency to the
highest test frequency, one test frequency at a time, with a one to three
second dwell time at each test frequency. The RF carrier is typically 80%
amplitude modulated with a 1 kHz sine wave.
As the calibration is performed into a 150 ohm system, and the
impedance of the line(s) under test is largely uncontrolled, the injected
current must be monitored during the test using a current monitoring
device to ensure that the current does not exceed the (I
max
) limit:
