1.0 Introduction
The ETS-Lindgren
Model 3816/2 Line
Impedance Stabilization
Network (LISN) is a
two-channel low pass filter
network designed to isolate
the Equipment Under Test
from an external power
source while steering any
radio frequency signals
from the power line to a
50-ohm port.
Model 3816/2 Front View
The conducted emissions measurements may be made in accordance with
regulatory compliance standards.
Data
Characterizations for each measurement port of the Model 3816/2 Line
Impedance Stabilization Network (LISN) are included with the unit. The graphs
provide individual plots of both impedance and insertion loss data.
A Certificate of Calibration Conformance is provided with each Model 3816/2.

2.0 Maintenance
Only trained service personnel should
perform adjustments and/or service
procedures.
Inside the Model 3816/2 are LETHAL
voltages with which you could come into
contact. Capacitors inside the unit may
still be CHARGED even when the unit is
disconnected from power.
Before performing any maintenance,
follow the safety information in the
ETS-Lindgren Product Information
Bulletin included with your shipment.
WARRANTY
Maintenance of the Model 3816/2 is
limited to external components such as
cables or connectors.
Clean the exterior of the cabinet using a
damp cloth and mild cleaner. Always
unplug the unit before cleaning.
To prevent electrical shock, do not
remove cover.
If you have any questions concerning
maintenance, contact ETS-Lindgren
Customer Service.

4.0 Installation and Application
Before connecting any components, follow the
safety information in the ETS-Lindgren
Product Information Bulletin included with your
shipment.
The Model 3816/2 is provided with resistors to
help bleed off high voltage transients, but it is
advisable to connect the input and output
connectors to their proper power lines and
loads before connecting the monitor port to the
measurement instrumentation; otherwise,
power surges or transients can damage the test
instrumentation mixers or attenuators.
The Model 3816/2 Line Impedance Stabilization Network (LISN) is nominally
designed for a 15-ampere current capacity, this rating may be increased to
16 amperes provided that the input and output connections are configured for
these currents.

Maximum line-to-line voltage must not exceed the 460 volts AC RMS.

Maximum line-to-ground voltage must not exceed 250 volts AC RMS.
The safety ground should be connected first
and disconnected last on the input side of the
unit.
An RF ground stud is provided on the front panel and rear panel for
bonding to the ground plane.
www.ets-lindgren.com
Installation and Application
13
The input power connection is made through a three-wire power cord utilizing the
accepted international color code. The input power cord opening is sized to
accept a standard electrical conduit fitting or strain relief (supplied). An
internally-mounted terminal strip provides the input connection point. When
connecting the conduit, disconnect the power cord from the terminal strip and
remove it.
Front Panel Connectors and Controls
BNC CONNECTOR
Connect the Model 3816/2 to the spectrum analyzer or EMI receiver through the
BNC connector.
RF GROUND
The Model 3816/2 is provided with an RF bonding stud on both the front and rear
panels. The unit should be bonded to a ground plane in normal operation.
EARTH LINE CHOKE SWITCH
The safety ground isolation choke selector switch switches the 1.6 mH earth line
choke IN and OUT of the safety ground circuit. The ground choke is designed
and manufactured with sufficient capacity to conduct the maximum current rating
of the Model 3816/2 and at no time is the safety ground of the unit compromised.
The earth line choke avoids a double RF ground connection (safety ground and
measurement ground) in the conducted emissions test setup.
ARTIFICIAL HAND
In conformance with EN55014 and BS800, the artificial hand connection is used
to test handheld equipment that is provided without earth connections.

Installation and Application
www.ets-lindgren.com
LINE SELECT SWITCH
Select the line to be monitored by the three-position selector switch. The line not
selected is internally terminated into 50 ohms. When using the remote (center)
position, connect the monitored line to the 9-pin connector on the rear panel.
Control signals are low-level 5 volt DC.

To monitor Line L1, apply +5VDC to pin 1 of the 9-pin connector.

To monitor L2, apply +5VDC to pin 3.

Should +5VDC be applied to both pins, the first pin to receive the
control signal will be selected.

As with manual selection, the line not selected is terminated into 50 Ω.

Pin 2 of the 9-pin connector is control common.
Although the unit is provided with resistors to
help bleed off high voltage transients, connect
the input and output connectors to their proper
power lines and loads before connecting the
monitor port to the measurement instrument.
Otherwise, you may damage the mixers or
attenuators of the test instrumentation due to
power surges or transients.
Switching between the two lines will not generate transients. Remove the power
source first when disconnecting power.

Back Panel Connectors
POWER INPUT
The input power connection is made through a jacketed three-conductor power
cable. This three-conductor power cable is rated at 16 amperes maximum. In
case of emergency, power can be removed from the unit by disconnecting the
Model 3816/2 input power plug from the power mains. Alternately, a properly
rated circuit breaker or switch which removes mains power from the unit can be
installed in proximity to the unit.
