1.1 Documentation
1.2 Introduction to PMM
Artificial Mains
Networks
Enclosed with this manual are a service questionnaire to send back to
NARDA in case of equipment service is needed, and an accessories check
list to verify all accessories enclosed in the packaging.
The objective of EMI Conducted tests is to define the amplitude of current I
c
and Voltage V
c
emission from the Device Under Test (DUT) onto the power
mains or to define the immunity of the DUT to the conducted interference.
The mains lines themselves do not allow for reliable EMI measurements
since their impedance is subject to marked variations that generates
different test results at different test sites.
The PMM Artificial Mains Networks are LISN used for RFI measurements
on AC three-phase, power supplied electric and electronic equipment
usable from DC to 60 Hz.
The LISNs are three line V-network with an equivalent circuit of 50 ohm //
(5ohm + 50µH), fully compliant with CISPR publ. 16, VDE 0876 and FCC
part 15 regulation.
The LISNs are suited to perform measurements on conducted interference
in the frequency range from 9 kHz to 30 MHz.
Designed according to criteria of cheaply and compactness they can be
used together with PMM Systems for Conducted Interference or any other
RF receiver.
The main functions performed by the Artificial Mains Network are:
• terminate the DUT with a standardized impedance against reference
ground;
• supply power to the DUT;
• insulate the test circuits against external interference coming, for
example, from AC-voltage network;
• route the EMI (Electro Magnetic Interference) of the DUT to the receiver,
in case of conducted emission measurement, and the EMI from the
signal generator to the DUT, in case of susceptibility test (current
injection).
The PMM LISNs are provided with a standard industrial power sockets, with
a pilot conductor connector provided.
According to EN 60309 (IEC 309) Normative the pilot conductor can be
used to operate a remote control switch, to avoid any mains connector
operation with high current load.

1-2 General Information
1-3 PMM Artificial Mains
Networks for
“CURRENT
INJECTION” test
As described above, a LISN is primarily a probe to take out RF signals.
Some particular EMC recommendations might require that Device Under
Test shall be proven to conducted EMC immunity in the range 10 kHz – 30
MHz, by injecting on the supply lines certain RF interference and checking
the DUT’s response.
PMM LISNs may be used also to this purpose by injecting a RF signal into
the RF output connector on the front panel.
The following figure shows the CISPR equivalent circuit.

Document L3EN-70206 - © NARDA 2007
6-2 Installation
6-4 Preparation for use
From the mains lines conductor to the case of the unit there is a high
leakage current.
The mains lines conductor is connected to ground via high value capacitors
due to the measurement system to be applied.
Over current protection is not provided in the LISN. The LISN must be
connected to a power mains which has the properly rated mains
protection installed.
The leakage currents between the phases and the earth line generally
exceed permitted limits for typical environments due to internal
capacitors; for this reason it is mandatory to use a current rated
insulating transformer to supply the PMM LISN Network.
PMM LISN Network, the insulating transformer and Equipment Under
Test must be provided by an appropriate current rated contact
breaker or fuses as closest as possible on the supply line and with a
safety indication of equipment operated by.
6-5 Pilot circuit
According to EN 60309 (IEC 309) Normative, the industrial mains plugs and
outlets, with an operating current, are provided with an auxiliary connector
called Pilot Circuit contact.
The Pilot Circuit contact is used to avoid mains plug disconnection
with an operating high current load connected. In this case a current
rated remote control switch shall be provided to allow a safe
automatic mains disconnection.
The Pilot Circuit contact and the remote control switch, connected
according to the following figure example, also allows to check
automatically the protection earth conductor continuity till the Device
Under Test mains connection.
Fig. 6-1 Pilot Circuit connection example
This is a Safety Class I equipment, it is provided with a protective
earth terminal. Before connecting this instrument, ensure that an
uninterruptible safety earth ground is provided from the main power
source to the product protective earth connection. If this instrument
is to be connected to other equipment or accessories, prior to
energizing either unit verify that a common ground exists between
them. Any interruption or loosening of the protective earth ground
conductor, either inside or outside the unit or in an extension cable
will cause a potential shock hazard that could result in personal
injury. Verify the safety earth ground functionality before operation.
Installation 6-3
6-6 Installation Check list
Before operation ensure the following steps are taken:
• Check the line voltage to ensure the compatibility with the equipment
requirements.
• Ensure that the to be provided fuse or breaker current rating is
appropriate for the equipment setup.
• Protection earth line is connected to mains supply input on the rear
panel.
• Ensure that cables and terminals used to connect PMM LISN Network
to supply line and to Equipment Under Test are suitable for the setup
current rating and proper safety insulation.
• Verify that 50 ohm RF cable to the EMI Signal Analyzer input be
disconnected before switch on or off the supply line.
• Prior to energizing either unit verify that a common ground connection
exists between all equipment in the test setup and safety protection
earth.
To allow correct equipment ventilation ensure that the vent grid on
the equipment covers be free by any obstructing object.

Operating PMM Networks 7-1
7 - Operating PMM Networks
7-1 Operating PMM
Networks
To operate the PMM Artificial Mains Networks connect the IEC plug on the
rear input to the mains insulating transformer.
To avoid any damage caused by transient current pulses, connect the RF
cable to the receiver only after the AC supply has been switched on.
The Equipment Under Test should be connected to the D.U.T. connector.
To select the phase line to be tested operate the phase knob on the front
panel, in this case there is no led indication.
Using PMM receivers the phase switching can be automatically performed;
in this case the phase under test will be indicated by the led in the front
panel.
To avoid any damage caused by transient current pulses, disconnect
the test Signal Analyzer input before switching AC supply on or off
To allow correct equipment ventilation ensure that all the vent grids
on the equipment covers be free by any obstructing object.
The PMM LISN continuous operation at higher current limit shall not
exceed one hour, a rest period of at least a half hour shall be
observed to allow the equipment to cool down.

7-2 Operating PMM Networks
7-2 Test Set-Up
Considerations
Measurement repeatability is the main concern of standards and
regulations, that exactly define the test set-up for interference
measurements. The Artificial Mains Network complies with CISPR publ.16
(part 2), VDE 0876 and the American FCC part 15 rules and regulations.
The test SET-UPs required for various standards are largely identical; a
detailed description is given in VDE 0877 part 1. (par. 9.2 "Measurements
using LISNs").
The DUT has to be positioned on a non-metallic or conductive table (height
>80cm.), 40 cm. in front of a metallic grounded wall with dimensions of at
least 2 m. x 2 m.
The table may also be used inside a screened room.
The distance of the DUT from any metallic part may affect the measured
RFI voltage values; VDE 0877 exactly define the dimensions for the test
configurations, by means of the following drawing:
Fig. 7-1 Typical test set-up
The figure 7-1 describes the test configuration and the interconnection of a
mains operated DUT, according to the above mentioned VDE specification,
where:
1. Metallic grounded wall;
2. Device Undet Test (DUT);
3. Folded mains cable fixed with strips of adhesive tape;
4. Non-metallic table;
5. RFI measuring receiver;
6. Line Impedance Stabilization Network (LISN) with:
B - connection to reference ground.
P - jack for DUT.
M - coaxial connection to measuring receiver.
All dimensions are given in centimeters.
Internal hardware checks and repairs shall be performed only by
NARDA authorized assistance and service centers.
The manufacturer, the worldwide distributors and the national
distributor agents shall not be responsible and kept liable for
damages to goods, to instruments or persons caused during
unauthorized operations on the instrument, or by manumitted
instrument.
Operating PMM Networks 7-3
7-3 Network verification
and maintenance
To verify proper operation of the PMM Networks use the following test
procedure:
Do not connect any AC or DC supply to PMM Networks during this
verification test.
Test equipment needed:
1. RF Generator and level measuring calibrated instrument or
2. Spectrum Analyzer with Tracking Generator.
In both cases, instrument shall be working at 1 MHz.
Verification test procedure:
1. Connect the RF signal (or tracking signal) to the mains output of L3-100
making sure that the ground is connected to the shield of the RF cable
(grounded). The RF signal (or tracking signal) shall be taken to L1 and
L2 sockets, alternatively
2. Connect PMM Networks RF output 3 to the level-meter input (or
