IEC 1010 Compliant

EMCO’S LISN Model 4825/2 is a two-line,

low pass, filter network used for con­ducted emissions measurements. The
product is placed between the power
mains and the equipment under test
(EUT) to stabilize line impedance,
provide a 50 ohm RF connection, and
eliminate unwanted RF signals from the
line supply.

LISNs play an important role in achiev­ing test accuracy. Without a LISN,
conducted interference on the power
mains can disrupt measurement
reliability. Also, line impedance variances
from one test site to another can degrade
repeatability. With a LISN integrated into
the test system, conducted RF interfer­ence is filtered and a stable line imped­ance is assured.

The Model 4825/2 is designed and tested
in accordance with IEC Publication 1010,
Safety Requirements for Electronic
Measur ing App aratus. It has als o received
CSA safety certification from the
Canadian Standards Association, a
further indication of EMCO's commit­ment to safety.

This product covers the frequency
spectra of 9 kHz to 30 MHz and is
designed to be used with a signal

analyzer for making FCC 15, VDE 0871 &
0875, EN 55022 and CISPR 22 conform­ance measurements.

Features

Earth Line Choke

A safety ground isolation choke selector
switch, located on the front panel,
switches the 1.6 microhenry earth line
choke "IN" and "OUT" of the safety
ground circuit. When the selector is
switched to the "IN" position, the unit
isolates the EUT from RF ground while
maintaining a safety ground.

Artificial Hand

An Artificial Hand circuit which conforms
to EN 55014 and BS 800 is included. The
circuit is useful for testing hand-held
equipment which does not have a
connection to protective earth ground.

High Pass Filter

A high pass filter is included on each
monitor port, preventing potential
overload to the analyzer and eliminating
the need to apply correction factors to
measurements.

Overcurrent Protection

To protect test equipment, a switchable,
two-pole circuit breaker is mounted on

LISN Model 4825/2

the rear panel. Providing excellent
overcurrent protection, the circuit
breaker is rated at 250 VAC, 50/60 Hz at
25 amperes.

EUT Power Adapter Boxes

The EUT is connected to the LISN
through an interchangeable power
adapter mounted on the front panel of
the unit. This convenient feature enables
users who are responsible for testing
products with worldwide distribution to
quickly switch from one receptacle type
to another. Please specify the receptacle
types required when placing an order.
One (1) adapter box with a single
receptacle type is standard. See Options
section for details on ordering more than
one type of adapter box.
