System 2050 is a highly versatile, modular, multi-role EMC test
facility adaptable to meet a wide variety of test specifications,
from compliance with basic national and international
standards, through detailed design characterisation to
compliance with manufacturers’ own, more exacting EMC
specifications. Its modularity offers each test lab a
configuration to suit its test needs cost-effectively while
remaining expandable so that, as test needs grow and change,
System 2050 can be extended accordingly, thereby protecting
investment.

Conducted Immunity EMC Test System
Intelligent Mainframe
At the heart of System 2050 is the
NSG 2050 mainframe unit, consisting of
a micro-processor based control unit, a
high voltage source and accommodation
for user selected plug-in pulse networks.
Each of the System 2050 plug-in modules
and extension units comes complete with
its own firmware, so that the system
automatically recognises its presence and
presents the user with the appropriate
software menus and front-panel options.
Intelligent control is effected either
through the front panel controls and
display or via a PC.
Further, System 2050 is designed for
inter-compatibility, using openarchitecture principles and modular
Windows control software. As such, it
can be combined seamlessly with any
of Schaffner's specialist test and
measurement instrumentation and with
third party products, including radiated
interference test equipment, in a
complete ProfLine test system to meet
the most demanding test needs.
A Complete Conducted Immunity Test
System
System 2050 offers a complete set of
plug-in networks for full compliance
testing to basic, generic and product
standards, for single-phase and threephase power lines as well as data and
telecom lines. The mainframe unit and
three plug-in networks (PNW 2055 surge
and PNW 2225 fast transient pulse
generators and PNW 2003 a power
quality module) make up a complete,
integrated system for testing
susceptibility to conducted interference
on single-phase power lines.
System 2050 may include just one or
several modules and each of these
provides a self-contained test facility that
requires no external coupling unit for
single-phase power line immunity tests to
the basic standard. As requirements
change in the future, System 2050
remains expandable with further networks
and extensions for new applications.
PNW 2055
is a basic surge generator complying with
IEC 61000-4-5 that provides a hybrid
surge pulse of 1.2/50µs - 8/20µs, with
built-in coupling for single-phase
equipment up to 16A.
PNW 2225
generates burst pulses according to
IEC 61000-4-4 and offers a range of
additional test parameters.
It includes a built-in processor-controlled
16A coupling network.
PNW 2003
is a versatile power network quality
simulator which generates drop-outs,
dips, interruptions and variations. The
correct functions for compliance testing
are pre-programmed and no external
device is needed.
An additional wide range of high current,
high voltage pulse generator plug-in
networks and external single-and threephase extension units is available for
more demanding industrial test
applications. These can be used to
create a complete user-defined system
for testing to, and beyond, the full IEC,
ANSI, IEEE, VDE standards and European
Norms.

PNW 2050
provides high energy hybrid surge pulses
of 1.2/50µs - 8/20µs with an extended
voltage range as required by IEC, ANSIIEEE and many other standards. It is
used with single- and 3-phase power-line
coupling networks or data-line couplers.
The network can also be used, in
conjunction with an antenna, for pulsed
magnetic field testing, e.g. to
IEC 61000-4-9.
PNW 2051
provides a 10/700µs pulse, as specified in
telecom applications and also required in
some industrial electronics standards, e.g.
IEC 61000-4-5. For higher test
specifications, PNW 2051 also provides
the sharper pulse rise time of 0.5µs. The
matching pulse networks, required in
some applications, are available.
PNW 2052
generates a 100kHz ringwave, as required
by the ANSI-IEEE standard. It can be
used with external coupling unit CDN 131
or CDN 133 for single-or three-phase
testing up to 25A.
PNW 2056
is a high frequency pulse generator which
produces damped oscillatory waves of
100kHz and 1MHz with amplitudes up to
4kV.
Coupling Units
A comprehensive range of couplers and
extension units is available for single- and
three-phase power-line and data-line
testing. Full technical details are outlined
on page 44.
CDN 131 and CDN 151
are designed to couple surge pulses and
fast transient pulses respectively to
single-phase power lines. They can be
used with all the surge and fast transient
pulse generator networks, for testing up
to 240Vac and 25A.
CDN 133 and CDN 153
are providing three-phase coupling for
tests up to 440Vac (phase to phase) and
25A continuous operation.
All combinations of coupling modes are
selectable under software control. There
are separate inputs for high energy surge
pulses and high frequency burst pulses
with one common output to the
equipment under test.
NSG 642
is an automated variable AC source which
can be used as a second supply with the
drop-out simulator PNW 2003 to generate
a wide range of dynamic voltage
variations including over-voltage, ramps
and dips. Meets the requirements of
IEC 61000-4-11.

Telecom Test System
A range of specialist telecom test plug-in
networks for System 2050 is available for
testing to current telecom standards
around the world, including CCITT, FCC,
IEC, Bellcore and ETSI. There is also a
full set of coupling units available, for
coupling fast transient and surge pulses
to two-wire, four-wire, multi-wire PABX
and ISDN lines.
PNW 2051
generates 10/700µs and 0.5/700µs test
pulses as used in telecom specs such as
CCITT. Normally applied in non-powered
test arrangements, it can also be used
with coupling networks for powered
system tests.
PNW 2053B
provides all pulses required by the new
FCC part 68 standard in one device.
FCC part 68 specifies the test methods
for all classes of terminal equipment in
the telecommunication environment.
The test arrangement includes a
dedicated coupling unit, CDN 141, with a
decoupling network for the 2/10µs power
line test pulse and coupling facilities for
telecom line test applications.
Components’ Test System
Components are often tested in, or close
to, the manufacturing area.
System 2050 offers the required safety
standards and operating flexibility, as well
as ready to use adapters.
Test sequences are prepared by the
system administrator then simply called
into operation by the operator.
Manipulation errors are avoided and the
test results can be recorded
automatically. The system can be used
as a platform for a wide range of test rigs
from a self-contained test bench
arrangement, to complex computer
controlled set-ups with integration of
power sources and measuring equipment.
