All mains driven types of generators are equipped for high voltage working safety in accordance with VDE
0104.
The EMC compatibility has been tested with EN 61326 version 03/2002.
1.10 Reduction of operational safety
If you have any reasons to suppose that the test equipment is not completely safe, you must shut it down and
put it out of operation. Moreover, you must mark or label the equipment appropriately so it will not inadvertently
be put into operation again. You should then call authorized service personnel for assistance.
1.11 As agreed use
The tester may be used exclusively for simulation of automotive EMC events.
1.12 General instructions
CAUTION!
Use of the generator is restricted to authorised and trained specialists.
DANGER!
Output connections must not be handled while pulses are being generated.
During pulse generation, high voltages and currents are present at the output
terminals. BNC output connectors are accessible and can have hazardous live
voltages present while in operation.
The generator is to be used only for the purposes set down by the manufacturer. It is the user’s responsibility
to ensure that the test set-up does not emit excessive radiation that may effect other equipment. The instrument itself does not produce excessive radiation. However, applying interference pulses to an DUT may cause
that DUT and its cables to start radiating EMI. The method recommended by standards bodies to prevent
unwanted emission is to operate the test set-up in a Faraday cage.
DANGER!
The construction of the unit renders it unsuitable for use in an explosive atmosphere.
DANGER!
Persons fitted with a heart pacemaker must not operate the instrument nor
approach the test rig while it is in operation.
Only approved accessory items, connectors, adapters, etc. are to be used to ensure safe operation.
9
10
1.13 Installation
The instrument conforms to protection class 1.
Local installation regulations must be respected to ensure the safe flow of leakage currents.
DANGER!
Persons fitted with a heart pacemaker must not operate the instrument nor
approach the test rig while it is in operation.
Two independent protective earth connections are necessary (instrument and DUT supply) connected back
to the local permanent installation or to a fixed, permanent protective earth conductor.
Operate the equipment only in dry surroundings. Any condensation that occurs must be allowed to evaporate
before putting the equipment into operation. Do not exceed the permissible ambient temperature, humidity or
altitude. This equipment must not be used in an enclosed space that would restrict the air flow through the
instrument.
Use only legally approved connectors and accessory items. The instrument must be powered from a mains
supply that provides a properly earthed mains socket. Before the unit is powered up, check that the voltage
selector on the instrument is set to the correct position.
Ensure that a reliable return path for the interference current is provided between the DUT and the generator.
The reference ground plane and the earth connections to the instruments as described in the relevant test
standard serve this purpose well.
The instruments must not in principle be opened. This may only be undertaken by a qualified specialist if specifically instructed to do so in the operating manual. Since the equipment generally works with two independent
power supplies for the generator and the DUT, the instrument must first be disconnected from both sources
before any changes are made. Besides the mains supply itself, certain instruments also operate at high voltages
which are not provided with any internal form of extra protection against being touched.
Ensure that all unused slots are blanked off before powering up.
NSG 5500 Automotive transient immunity generator
1.14 Test execution
The test area must be so organised that no unauthorised persons have access during execution of a test.
DUTs, together with their accessories and cables, are to be considered as being live during a test. The test
generator must be stopped and the DUT supply interrupted before any work is carried out on the DUT. This
can be implemented by pressing the “SYSTEM STOP” button.
DANGER!
The DUT is to be tested only in a protective cage or under a hood which provides
protection against electric shock and all manner of other dangers pertaining to
the particular DUT (see Dangers concerning the DUT).
CAUTION!
The safety instructions concerning all the instruments and associated equipment
involved in the test rig are to be observed.
CAUTION!
The configuration of the test rig is to be strictly in compliance with the methods
described in the relevant standard to ensure that the test is executed in a standard
conforming manner.
1.15 Dangers concerning the generator
DANGER!
Dangers from a disrupted DUT.
DANGER!
Local burning, arcing, ignition of explosive gases.
DANGER!
Danger from the resultant DUT supply current caused by a flashover or breakdown
resulting from the superimposed high voltage effects.
DANGER!
Disturbance of unrelated electronics, telecommunications, navigational systems
and heart pacemakers through unnoticed radiation of high frequency energy.
In most test rigs the interference voltage is superimposed on the protective earth conductor of the DUT in
accordance with the requirements of the test standard. Earth contacts or pins (e.g. in German and French
connectors) as well as the DUT earth can hence be at a dangerous to touch voltage. The screws, too, in certain
connectors are also linked to the protective earth conductor.
11
12
1.16 Dangers concerning the DUT
DUTs are often simply functional samples that have not previously been subjected to any safety tests. It can
therefore happen that in some cases that the DUT is quickly damaged by internal overloads caused by the
control electronics being disrupted or it may even start to burn.
CAUTION!
As soon as the DUT shows signs of being disrupted the test must be stopped and
the power to the DUT switched off.
DANGER!
Internal disruption of the electronics can result in the interference voltage or the
DUT supply voltage being present on the DUT‘s housing.
CAUTION!
Electrical breakdown or arcing from and in plugged connections that are overstressed voltage-wise during the test.
DANGER!
Explosion of electronic components with fire or fragmentation as a result of the
energy dissipated, e.g. from the resultant supply current or ignition of vaporised
plastics materials.
CAUTION!
Faulty behaviour by the DUT, e.g. robot device strikes out, temperature controller
fails, etc.

2.9 Installation / set-up control unit (CTR)
There are three controllers in circulation: The CTR 5500 and CTR 5501/02. The CTR 5501/02 has some small
changes: it supports a new USB connection and has a new method of updating the firmware.
CAUTION!
The IEEE Bus has proven to be a very reliable control method in industrial environments. However, the CTR 5501/02 supports also USB control. Please note that
USB can be affected by disturbances in typical EMC laboratories. For this reason,
please use only the supplied USB cable.
Only cables confirming to the USB 2.0 standard and above are supported. Even so,
in very noisy environments, the IEEE 488.2 connection is recommended.
2.9.1 Setting the IEEE address
2.9.1.1 IEEE address setting CTR 5500
When communicating with the NSG 5500 via the IEEE 488 Interface it is necessary that the address set in the
AutoStar comm setup screen corresponds with the IEEE 488 address set on the control unit.
A DIP switch array on the front panel of the control unit is used to set the NSG 5500 IEEE address. There may be
five or six switches on this DIP switch, depending on the hardware version. Only the first five switches are used.
These first five switches correspond to the binary weighted address values 1, 2, 4, 8, and 16. The total sum
of the values corresponding to the switches in the “ON” position is the IEEE address. For example, in the
illustration below, the address set is 1 + 2 + 8 = 11.

3.2 NSG 5500 Operation
3.2.1 Introduction
The NSG 5500 EMC test system is designed for testing automotive electronic components and parts. Automotive EMC test requirements are covered in ISO 7637-2, ISO 16750-2 and many OEM standards and requirements.
These standards outlines five basic pulse types that are used for automotive EMC testing. The NSG 5500 system
is a modular instrument that can generate all of the pulses described in the ISO standard and in many cases
to a higher specification than that specified in the standard.
The NSG 5500 is a modular instrument where the pulse generators are designed as plug- in modules that fit
into the NSG 5500 mainframe.
Picture 3–2: NSG 5500 mainframe with module and pulse assignment.
MT 5511
FT 5531
LD 5550
NSG 5500 Automotive transient immunity generator
Due to the modular structure of the NSG 5500 you may configure a test system that provides only the pulse
requirements that are required for your application by installing additional modules as needed.
NOTE!
Pulses of similar specification and energy requirements are usually housed in the
same plug-in unit. For example the ISO pulses 1 and 2a are all supplied within the
same plug-in.
The NSG 5500 is fully programmable over USB or RS 232 and IEEE 488 interface bus. A Windows program
«AutoStar» is available to provide full remote control via a PC computer. This program allows you to generate
pulse sequences, including dynamic ramping, and to generate hardcopy printouts of the test results.
The main features of the NSG 5500 could be summarised as follows:
Modular construction, pulse modules plug into main chassis
Exceeds specifications set out in the ISO, DIN and SAE standards
Remote controllable via USB or RS 232 and IEEE 488
Internal multiplex bus system (all pulses available from the front of the FT 5531 plug-in)
Compact construction, 12 inches high (30 cm)
19 inch rack mountable
Windows software program provided
DUT FAIL, START/STOP, TEST END, AND CRO trig signals available for interfacing with other test
equipment
3.2.2 Powering up the system
Switch on the NSG 5500 by switching on the main switch on the rear side in the power entry unit.
CAUTION!
The hardware requires at least 10 seconds to boot. Reliable software communications can not be established until the system is completely booted!
DANGER!
When any Pulse 4 control is used, the power amplifier/battery simulator should
always be turned on last to assure safe and reliable control of the power amplifier/
battery simulator. Do not, under any circumstances, touch the outputs or connect
any DUT to the outputs of the system during booting!
35
3.2.3 NSG 5500 System overview
The NSG 5500 mainframe is designed to take the pulse plug in units from the front. The system support
electronics are plugged in from the rear.
36
Picture 3-3: NSG 5500 Rear view.
These rear plug in units are not generally removed by the user. These units have a modular construction to
facilitate easy maintenance and to allow for future upgrades to the NSG 5500 system. The plug-in units in
question are,
HV-PSU 5500: this is a solid state high voltage programmable power supply that provides the required
charging voltage to the pulse generators.
CDN 5500 or CDN 5501: this unit contains a solid state switch and timing electronics which are used for precise
timing control of the “ON“ and “OFF“ periods of the battery power supplied to the device under test (DUT).
This is required to meet some of the timing requirements specified in the standards, particularly for negative
pulses.
CTR 5501 or CTR 5502: this unit contains the processor board that controls the complete system.
The remote control interfaces USB and IEEE 488 are also available via this unit.
NOTE!
The difference between the CTR 5501 and CTR 5502 is that the CTR 5502 can be
upgraded with up to eight ARB 5500 arbitrary waveform generators.

Picture 3-4: CDN 5500
If a DC source with remote sense is being used to simulate the battery input (i.e. supply power to the DUT) then
the sense inputs can be used to ensure that the voltage at the main source Input is accurate by compensating
for voltage drops in the lines. If a pulse 4/2b amplifier is supplied with the test system then this can also be
used as the battery input for all the other pulses. The mains Input unit is fitted with two 3.15 A / 6.3 A time-lag
fuses. This is intended to protect the internal power bus in the case of an overload condition.
The difference between the CDN 5500 and CDN 5501 is that the CDN 5501 can be upgraded with an additional
S1, S2 and S3 dropout switches. Both contain the CDN needed battery switch for during Pulse 1 testing, and
generally switching the DUT on and off.
NOTE!
The difference between the CDN 5500 and CDN 5501 is that the CDN 5501 can
be upgraded with an additional S1, S2 and S3 dropout switches. Both contain the
CDN needed battery switch for during Pulse 1 testing, and generally switching
the DUT on and off.
37
Mains input power is brought into the system via the power entry module. The power entry module has a
mains input power filter socket that allows for adjustment between 110/120 VAC and 220/240 VAC operation.
This filter socket contains the two 3.15/6.3 A fuses.

The battery switch unit is an electronic solid state switch that allows flexible control of the power bus output
during the generation of interference pulses - for example pulse 1. (ref. ISO standard 7637-2).
The requirement for sophisticated switch control when generating ISO 7637 pulses is not immediately apparent.
However, upon deeper examination it will become clear that the requirement for turning “ON“ and “OFF“ the
battery power can only be met with a complicated solid state switch arrangement. This is because high power
current needs to be switched over very short periods of time and by different control mechanisms.
Take for example pulse 1 of the ISO 7637-2 specification.
< 100 µSec
ISO 7637 - Pulse 1
Battery “OFF“ here
Battery
“ON“ here
Picture 3-6: Pulse 1 of the ISO 7637-1 specification.
NSG 5500 Automotive transient immunity generator
The voltage drop of the switch is minimal (see chapter 5.1 Technical specifications). The sense inputs are
terminated at the switch, except in pulse 4 applications where the 4 continue through the output connector
on the front panel of the FT 5531.
Upon detailed analysis of this pulse requirement it becomes clear that there is a requirement for the battery
power to switch “ON“ and “OFF“ during pulse generation.

The switch has facilities for being controlled by a voltage sense circuit or a timer circuit. While it is obvious
that the control of the battery switch to the required specification requires complicated timing and monitoring
controls, all of this activity is generally transparent to the user. The control unit in the NSG 5500 manages all
of these requirements internally and automatically, as required, during pulse generation.

The generator supports either USB or RS 232 and GPIB communication. The syntax of these commands is
discussed in chapter 3.2.4 Remote programming. However, AutoStar is programmed with these commands
and therefore, detailed understanding of the syntax is unnecessary unless the system is to be integrated into
another software package other than AutoStar.
3.2.3.4 HV-supply
This unit is used to charge the pulse generators. It is a solid state electronic power supply that is capable of
supplying the necessary high energy bursts of power required to charge all of the pulse generator capacitors
used in modules contained in the NSG 5500 mainframe system.
The HV - supply is fully programmable and is controlled on the internal
bus by the control unit.

3.3 FT 5531 Operation
3.3.1 Introduction
The FT 5531 (FT = Fast Transients) is a plug-in burst generator designed for use with the NSG 5500 mainframe
system. This generator is designed primarily to meet the specification requirements for the ISO 7637
standard for pulses 3a and 3b. In many cases the specification of this generator exceeds those specified in
the ISO 7637 standard.
When slotted into an NSG 5500 mainframe, the FT 5531 burst generator is fully programmable via USB or RS
232 or IEEE 488 interface. Parameters such as amplitude, burst frequency, pulse frequency, number of pulses
in the burst, number of bursts are all under program control. This allows flexible test patterns to be generated
which can facilitate rapid analysis of susceptibility limits of a device under test.
The FT 5531 is designed using state of the art semi-conductor technology. This means repeatable performance
and maintenance free operation. It also means that test results can be repeated accurately.
The output pulses of the generator are available on two connectors, a 50 Ohm BNC connector and a pair of 6
mm sockets. The 6 mm socket output has the added advantage in that it forms part of the multiplexed power
bus within the NSG 5500 system. This means that output pulses for other plug-in units are also available on
the socket output of the FT 5531 module. This can simplify fixturing to the device under test.
NOTE!
The AutoStar program available from Teseq is a Windows based graphical program
which allows full control of all programmable features via an intuitive graphical
windows front panel.
The BNC output connector must be chosen from AutoStar. NO DC is present at
this connector and it is meant for pulse 3 only.

3.4 LD 5550 Operation
3.4.1 Introduction
The LD 5550 (LD = Load Dump Generator) is a plug-in high energy generator module designed for use with
the NSG 5500 mainframe system. It is designed primarily to meet the specification requirements for the ISO
7637 standard for pulses 5. In many cases the specification of this generator exceeds those specified in the
ISO 7637 standard.
49
When slotted into an NSG 5500 mainframe the LD module is fully programmable via USB or RS 232 and IEEE
488 interface. Parameters such as amplitude, pulse frequency, pulse width, are all under program control.
The LD 5550 is specified in the ISO 16750-2 (previously ISO 7637-2) standard, which defines how the pulses
are generated in relation to the vehicle battery voltage. When operating with a battery or battery simulator
connected to the NSG 5500 mainframe, the CDN 5500 battery switch module should also be mounted in the
rear of the NSG 5500 chassis. This module provides the necessary switching on and off of the battery voltage
according to the standard.
The module is designed using state of the art active pulse-shaping technology. This means repeatable performance and maintenance free operation. It also means that test results can be repeated accurately.
The output pulses of the generator are available on two 6 mm sockets on the front of the NSG 5500 instrument.
NOTE!
The AutoStar program available from Teseq is a Windows based graphical program
which allows full control of all programmable features via an intuitive graphical
windows front panel.

3.5 MT 5511 Operation
3.5.1 Introduction
The MT 5511 (MT = Micro Transients) is a plug-in transient generator module designed for use with the NSG
5500 mainframe system. This generator is designed to meet the specification requirements for the ISO 7637
standard for pulses 1, 2a, 6 and similar. In many cases the specification of this generator exceeds those
specified in the applicable standard. The MT 5511 complies with ISO 7637:2011, with previous versions of the
standard and also meets many proprietary automobile manufacturer standards.
The MT 5511 generates pulses of types 1, 2a and 6, as specified in the ISO, SAE and Ford™ standards. This
standard defines how these pulses are generated in relation to the vehicle battery voltage.
When slotted into an NSG 5500 mainframe, the MT 5511 Micro transient generator is fully programmable either
via USB or RS 232 and the IEEE 488 interface. Parameters such as amplitude, pulse width and pulse rise time
are all under program control. This allows flexible test patterns to be generated, which can facilitate rapid
analysis of susceptibility limits of a device under test.
The output pulses of the generator are available on two 6 mm sockets on the front of the NSG 5500 mainframe.
The MT 5511 allows selection of different internal output resistances under software control. If enabled in
AutoStar, the Ri jacks will not internally be bypassed. This will allow to add an additional resistance to the
selected internal pulse output resistor.
NOTE!
The AutoStar software program, available from Teseq, is a Windows based graphical program that allows full control of all programmable features via an intuitive
graphical windows front panel.

3.6 ARB 5500 Arbitrary Waveform Generator
Systems ordered (or upgraded) with the +ARB Option contain one ARB 5500. Additional ARB 5500 modules
can be added at any service center.
A CTR 5502 can be equipped with up to eight ARB 5500 arbitrary waveform generators.
Each ARB 5500 contains the necessary +/- 10V control signal for driving a source like Teseq’s PA 5840 or PA
5740. The ARB 5500 also provides a 0-10V control signal is provided for Teseq sources with a programmable
current limit. A programmable TTL trigger is also provided.
The ARB 5500 has a bandwidth of 500 kHz and features stepless playback of many fully parameterized
waveforms:
The MT 5511 allows selection of different internal output resistances under software control. If enabled in
AutoStar, the Ri jacks will not internally be bypassed. This will allow to add an additional resistance to the
selected internal pulse output resistor.
The ARB 5500 has a bandwidth of 500 kHz and features stepless playback of many fully parameterized waveforms:
Sine Waves
Square Waves
DC
Ramps
Exponential (Rise and Fall)
Triangle Waves
Switching
A typical test is made of up one or more of these segment types. The NSG 5500 equipped
with the +ARB Option can perform 64,000 segments shared between up to eight channels.

3.6.1 The Hardware
The NSG 5500 can contain up to eight ARB 5500 modules, but it must be prepared to hold the modules. An
NSG 5500 +ARB already contains one ARB 5500, and some necessary electronics. Once the +ARB Option is
included, up to seven additional ARB 5500 modules may be added to control up to eight sources.
3.6.2 Connections
Each ARB 5500 contains not only a DB-9 output for connecting to the source, but also a BNC trigger.
As many sources, such as the Teseq PA 5840 and PA 5740 contain a voltage programmable current limit, this
is also provided.
