1.1 Documentation
1.2 Introduction to
PL01 Pulse Limiter
Enclosed with this manual are a service questionnaire to send back to
NARDA in case that equipment service is needed.
The Pulse Limiter PL01 is an accessory designed to protect the input circuit
of a Receiver against high energy interfering voltage pulses.
The Pulse Limiter does not cause any significant change of the measured
signal and loss in sensitivity on the measuring receiver.
Its main function is to suppress the transients that can occur when the test
item, connected to an artificial mains network LISN, is switched on or off.
When operating the receiver from artificial mains network LISN, the Pulse
Limiter PL01 must be used particularly when very strong interfering signal is
suspected. The precision input attenuator and the input mixer of the
receiver are therefore protected from being damaged.
On the other hand if the disturbance signal and spikes do not exceed the
maximum input voltage permissible for the receiver, the use of the Pulse
Limiter can be omitted.
Designed according to criteria of cheaply and compactness it can be used
together with PMM 9010F for conducted interferences measurement, or
any other RF receiver.
The following figure shows the Pulse Limiter typical frequency response.

1.3 Insertion loss
The insertion loss of the Pulse Limiter is calibrated in a 50 ohm system over
the frequency range of 9 kHz to 30 MHz, and is 0.4 dB maximum.
1.4 Environment The operating environment is specified to be within the following limitations:
•Temperature
•Humidity
0° to +45° C
< 90% relative
The instrument should be stored in a clean, dry environment
The storage and shipping environment is specified to be within the following
limitations :
•Temperature
•Humidity
-25° to + 70° C
< 95% relative
1.5 Return for service If the instrument should be returned to NARDA for service, please complete
the service questionnaire enclosed with the Operating Manual and attach it
to the instrument.
To minimize the repair time, be as specific as possible when describing the
failure. If the failure only occurs under certain conditions, explain how to
duplicate the failure.
If possible, reuse of the original packaging to ship the equipment is
preferable.
In case other package should be used ensure to wrap the instrument in
heavy paper or plastic.
Use a strong shipping container and use enough shock absorbing material
around all sides of the equipment to provide a firm cushion and prevent
movement in the container.
Seal the shipping container securely with shipment tape.
Mark the shipping container FRAGILE to encourage careful handling.

3.1 Introduction
This section provides the information needed to install and use the Pulse
Limiter PMM PL01.
Included is information pertinent to initial inspection, interconnections,
environment, cleaning and shipment.
3.2 Packing Unpacking
Inspect the shipping container for damage.
If the shipping container or cushion material is damaged, it should be kept
until the contents of the shipment have been checked for completeness
and the instrument has been checked mechanically and electrically.
Verify the accessories availability in the shipping container referring to the
accessories check list enclosed with the Operating Manual.
Notify any damage to the carrier as well as the NARDA Representative.
3.3 Initial inspection
Inspect the Pulse Limiter for damage before use.
To avoid hazardous electrical shock, do not use the Pulse Limiter
when there are signs of shipping damage to any portion of it.

WARNING

3-2 Preparation for use
3.4 Preparation for use
The male BNC plug of the Pulse Limiter must be connected to the RF input
socket of the EMI test receiver.
Pulse Limiter usage under some condition may affect the
measurement result in respect to test signal characteristics.
When test signal has very high pulses the Pulse Limiter may reach
saturation and affect measurement accuracy.
When very strong test signal is suspected the usage of a 10 dB or
more 50
Ω attenuator in front of the Pulse Limiter is strongly
recommended.
A verify if Pulse Limiter is reaching saturation can be carried out simply
performing two measurement of the suspected strong signal, respectively
with and without a 10 dB, or more, 50
Ω attenuator connected between test
signal and Pulse Limiter.
The measured test signal difference must match the attenuation
introduced: if the difference between the two measured signals is lower
than attenuator value it means that without using attenuator the Pulse
Limiter is reaching saturation, affecting therefore measurement accuracy.
In this case the final measurement must be carried out with attenuator
inserted taking into account the attenuator value in the test signal reading.
Before connecting Pulse Limiter to the associated test instrument,
ensure that an uninterruptible safety earth ground is provided from
the main power source to the EMI test receiver protective earth
connection.
To avoid hazardous electrical shock, prior to energizing either unit
and prior Pulse Limiter connection, verify that a common ground
exists between EMI test receiver and the equipment under test.
Any interruption or loosening of the protective earth ground
conductor, either inside or outside the units 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.
3.5 Equipment cleaning
Use a clean, dry non abrasive cloth for external cleaning of the Pulse
Limiter.
To clean the equipment do not use any solvent, thinner, turpentine,
acid, acetone or similar matter to avoid damage to external plastic
and surfaces.
