①Coupling Clamp
The coupling clamp main unit for coupling pulses to harnesses etc.
The unit is utilized by inserting a harness into the plates of the clump located on the
ceiling.
Stray capacity arisen between the harness and the plate transmits the high
frequency components onto the secondary side (harnesses) mainly by electrostatic
inductions. Therefore, the transmission gets harder as the noise components reach
a lower frequency range.
Since the transmission efficiency depends on the stray capacity between the
harness and the plate, the harness should be pinched by the plates as tight as
possible to increase the stray capacity.
The coupling would not take effect unless the coupling pulses have sufficient
energy of high frequency range.
Do not touch any portion of the clamp during pulse output. Otherwise you may get an
electric shock.
②Coaxial Cable (For Simulator Connection)
This is a 50Ωcoaxial cable with BNC connectors to connect the coupling clamp to
the simulator.
A BNC tangent line is attached.
One end is to be connected to the pulse simulator (ISS-7630 or ISS-P3ab), and the
other end is to be connected to the terminator.
③Coaxial Cable (For Terminator Connection)
A 50Ωcoaxial cable with BNC connectors to connect the coupling clamp to the
attached terminator
One end is to be connected to the coupling clamp, and the other end is to be
connected to the terminator.
④Terminator
A 50Ωterminal resistor for matching the transmission line (coupling clamp) with
50Ω.
The rated power of the terminator is 5W. Take every caution not to input the voltage
that gives higher effective power than the rating. In case of coupling pulses of the
ISS 7630 simulator or ISS-P3ab without DC voltage, It will be no problem.
⑤ Metal Fasteners
Metal pieces to fasten the simulator (ISS-7630) to the ground plane.
Attach them to 2 locations, at the FG terminals on the front and rear panes.
Refer to “8.1 Preparation of Testing”.

8. TEST PROCEDURE
8-1. Test Preparation
Before proceeding with the test, always carry out “10 Pre-Start Checkup (Waveform Verification).”
Prepare the installation environment and connect the cables. Set up according to the Standard
and/or other user requirements. An example is shown below.
・Installation
Place the Coupling Clamp, the simulator (ISS-7630 or ISS-P3ab), an
oscilloscope, and the power source (batteries) on the ground plane, and
secure each with screws. Use the Metal Fasteners attached to ISS-7360-Cup
to secure ISS-7630.

Clamp ①with Coaxial Cable ②. Connect the Coupling Clamp ①and the Terminator

Coupling Clamp, connect 20dB ATT in two series instead of the Terminator ④and
examine the waveform using an oscilloscope (50Ωtermination) after the 40dB
attenuation.
・Wiring the Simulator (for ISS-P3ab)
Connect the ISS-P3ab simulator’s Surge OUT BNC connector (Coupling Clamp) and
the Coupling Clamp ①with Coaxial Cable ②. Connect the Coupling Clamp ①and
the Terminator ④with Coaxial Cable ③. When evaluating the waveform after passing
the Coupling Clamp, connect 20dB ATT in two series instead of the Terminator ④and
examine the waveform using an oscilloscope (50Ωtermination) after the 40dB
attenuation.
・Connecting DUT
Connect DUT and peripheral connecting devices.
Insert the harness of DUT and the peripheral devices into the clamper portion
of the Coupling Clamp ①.

Since the waveform contains high frequency components over the range of 200MHz, the
malfunction level cannot be measured quantitatively if the free capacity and the
electromagnetic field radiation deviate due to placement of the simulator and DUT,
types of cables used, and the height from ground plane. This highly depends on the
physical positioning of devices under the testing environment. Thus, devices must be
always positioned in the same locations in order to realize quantitative tests.
8-2. Running DUT
Run DUT as it is used. Input signals preliminarily if necessary.
8-3. Starting Test
When the simulator (ISS-7630, ISS-P3ab) begins to output pulses, the pulse is coupled to the
harness.
Proceed according to the Standard or test plan.
For operation procedures of the simulator, refer to its manual.
Do not touch the clamper portion on the ceiling when outputting pulse. There is a risk of electric
shock.
The Terminator may burn out when tests are carried out coupling pulses to DC.
Always couple pulses without DC voltage.
To avoid coupling pulses to DC, be sure to turn OFF the DC LINE of ISS-7630. As for ISS-P3ab,
always connect from the Surge OUT BNC connector (Coupling Clamp).

always positioned in the same locations in order to realize quantitative tests.]
8-4. Finishing Test
To finish the test using ISS-7630, put it in STOP mode. As for ISS-P3ab, lower the
simulator output voltage to 0V and then put it into STOP mode.
Next, turn the power OFF.
Stop the operation (working status) of DUT, and shut the power supply off.
Remove the harness from the coupling clamp.

10. WAVEFORM VERIFICATION
Before proceeding to the coupling clamp tests, confirm that the simulator is transmitting pulses
normally. Refer to Figure 1. However, when verifying the waveform, harness must not be inserted
into the clamper portion. Insertion of the harness will alter the characteristic impedance and
cause reflections onto the waveform. The ISO complied procedure for waveform
verification is given below. Refer to ISO Standards for details.
・Place Coupling Clamp, the simulator (ISS-7630 or ISS-P3ab), and an oscilloscope on the
ground plane and screw fasten. Use Metal Fasteners ⑤for ISS-7630.
・Wiring the Simulator (for ISS-7630)
Insert the BNC Conversion Adapter (ISS-7630 accessory) into Output Connector (DC LINE
OUT/PULSE).
Connect the BNC Conversion Adaptor and Coupling Clamp ①with Coaxial Cable ②.
Connect the Coupling Clamp ①and 20dB ATT×2 (2 connected in series to attenuate 40dB) with
Coaxial Cable ③.
Connect 20dB ATT to oscilloscope (50Ωtermination) and verify the waveform.
・Wiring the Simulator (for ISS-P3ab)
Connect the simulator ISS-P3ab Surge Out BNC connector (Coupling Clamp) and Coupling Clamp
①with Coaxial Cable ②.
Connect the Coupling Clamp ①and 20dB ATT×2 (2 connected in series to attenuate 40dB) with
Coaxial Cable ③.
Connect 20dB ATT to oscilloscope (50Ωtermination) and verify the waveform.

waveform shown in the specifications of the simulator.
Do not touch the clamper portion of the ceiling when outputting pulse.
There is a risk of electric shock.
