1.0 Introduction
The ETS-Lindgren Bulk Current Injection Probe (BCIP) Series is used to
inject RF current into conductors and cables of electrical and electronic
equipment undergoing susceptibility testing. This manual includes information for
these BCIP models:
• Model 95236-1
• Model 95242-1
The BCIP provides a means of applying a controlled RF stress level to an
instrument under test through interconnecting cables or power cables without
requiring a direct connection to the conductor(s) of interest. The models in this
series are simply clamped around the test conductor which then becomes a
one turn secondary winding, with the current probe forming the core and primary
winding of an RF transformer. RF energy can be injected onto single and
multi-conductor cables, grounding and bonding straps, outer conductors of
shielding conduits and coaxial cables, and so on.
Because of the high efficiency design, the probes can also be used as sensors.

95242-1 10 MHz–400 MHz 2 MHz–400 MHz
The BCIP Series is especially designed to provide minimum insertion loss

Supporting Equipment
Contact ETS-Lindgren for sizes and sensitivities of other current
probes.
When using the Model 95242-1 to perform susceptibility tests, the following
equipment may be required.
OPTIONAL INJECTION PROBE
The Model 93686-1 Current Probe with a 6.6 cm window diameter may be used
as a bulk current injection probe over the frequency range 50 kHz to 2 MHz.
MODEL 95241-1 CALIBRATION JIG
The Model 95241-1 Calibration Jig is used in equipment setup for measuring
insertion loss of the current probe and is essential to set up equipment for some
susceptibility test procedures.
CURRENT MONITORING PROBES
Suggested current monitoring probes are Model 91550-1 (10 kHz to 100 MHz)
and Model 94111-1 (1 MHz to 1 GHz). These probes have a 1.25-inch (3.2-cm)
window size and a transfer impedance of 1 ohm to 6 ohms over the 50 kHz to
400 MHz frequency range.
8 | Introduction
Operation: Precautionary Measures
Before connecting any components, follow the
safety information in the ETS-Lindgren
Product Information Bulletin included with your
shipment.
RF fields can be hazardous. Observe
appropriate RF exposure limits.
When measuring conductors that are not
insulated, use extreme care when installing the
current probe and taking measurements. If
possible, de-energize the test sample during
assembly and disassembly of the setup. Also,
arrange to center the test conductor in the
current probe window for additional voltage
breakdown protection.
Do not permit the uninsulated current probe
connector and cable connectors to come in
contact with the ground plane or other nearby
conductors. This will prevent possible
measurement error due to ground loops, and
will avoid danger from high voltages.
Ensure that the 50-ohm load is capable of safely
dissipating the incurred power. Should the load
become disconnected, the developed voltage
will be come much greater and may be very
dangerous.
