DANGER! The “SYSTEM STOP“ button does not disconnect the test system from the line voltage! If a danger for life, machine or the product occurs, the “SYSTEM STOP“ button must be pressed! Thereby the test voltage in the DUT is disconnected. NOTE! After resetting the “SYSTEM STOP“ button, the test system must be restarted before continuing operation is possible. 7 8 1.6 Safety of operation Reliable function and safe operation of the test equipment are ensured only if the relevant general precautions as well as all safety instructions given in this manual are observed. In particular, observe the following: Connect the generator only to line voltage that confirms to the power specification given on the type label (on the back of the test system). Do not touch any conductive parts at the test point connectors, the fixture and the test object during a test run. Never apply external voltage to the sytem’s output connectors. Disconnect the generator f rom the mains before opening the casing for maintenance or repair. During operating the generator always observe the relevant rules of ESD (Electro Static Discharge) protection. To guarantee the EMC features of the NSG 5500, the control computer must meet the requirements of the EN 50082, 55011, 61000 standard. The operation of radio equipment or other high frequency emitting devices near the DUT or adaptation cables, may possibly lead to wrong test results (while HF energy is emitted). Observe the environmental conditions as described in chapter 5.3 Environmental conditions. 1.7 Personnel The generator may be operated by qualified personnel only. It may be opened for adjustment, maintenance or repair by authorized staff only. Teseq or its representative may not be held responsible for service not performed by Teseq personnel. 1.8 Responsibility for safety precaution The owner, operation supervisor and/or operator of the equipment are responsible for safety. The owner, operation supervisor and/or operator are in charge of any safety measures that do not directly concern the generator itself. For details, see the relevant accident prevention regulations. See also the safety instructions in the manufacturer’s manual included with any additional instrument or device you intend to use with your Teseq equipment. Neither Teseq AG nor any of the sales organisations can accept any responsibility for personal, material or consequential injury, loss or damage that results from improper use of the equipment and accessories. 1.9 Safety regulations According to the EN 50191 standard, this equipment may involve the risk of electric shock. The owner, operation supervisor and/or operator are responsible to build-up and operate the equipment according to the EN 50191 standard. Conductive parts must not be touched, and the test station must have appropriate warning labels and signs. In general, observe the industrial health and safety standards pertaining to electrical test installations in your country. The construction of the equipment conforms to the safety requirements of IEC 348 and provides all the prerequisites for safe and reliable operation. Development and manufacture is in compliance with ISO 9001. The equipment conforms to the safety requirements of IEC 1010-1/EN 61010-1 (safety requirements for electrical equipment for measurement, control and laboratory use). The switching power supply conforms to IEC 950. NSG 5500 Automotive transient immunity generator 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. NSG 5500 Automotive transient immunity generator 2INSTALLATION 2.1 Checking the shipment Upon receiving the shipment, first check the packaging and outer equipment cover for visible damage.

The NSG 5500 may be set up by qualified personnel only. It is imperative to observe the safety instructions at the beginning of this manual. Check that all items and accessories ordered have been delivered. Inspect the equipment for damage during transit. Any damage found should be reported to the carrier immediately. Carefully study the documentation and operating instructions supplied. The mains voltage selector on the rear of the instrument must agree with the local mains voltage (mains frequency: 47–63 Hz) Connect the mains cable to a mains outlet that has a good earth connection. Ensure that all modules are inserted correctly and screwed home tightly. Observe, and adhere to, the polarity of all input and output connections. Power up and operate according to the instructions supplied. NOTE! The three modules contained herein are simply the most commonly required transient generators. Additional generators are available for use in the NSG 5500. These additional generators will be supplied with their own user’s guide. 17 18 2.6 Installation / set-up FT 5531 Check the instrument for any mechanical damage. Report any damage found to the carrier immediately. NOTE! The FT 5530 and FT 5531 are functionally identical and may be used interchargeably in this guide. Differences are noted where necessary Ensure that the power is turned off on the NSG 5500 mainframe and that the battery input is disconnected. Insert the cassette in the second slot from left and push in fully. Screw in the four retaining screws fully. Turn on the mains input power on the NSG 5500 mainframe. After approximately a two second delay the power LED (red) on the FT 5531 generator should light. Now the scope calibration setup shown in picture 2-7 should be connected and the output pulses should be quickly checked to ensure that they are of the correct form and shape. When pulses are generated the green LED (3a or 3b, whichever is selected) flashes as pulses are output. 2.6.1 Test set-up The following set-up can be used to check the integrity of the output pulses. Due to the high frequency nature of the 3a and 3b pulses it is critically important that cable lengths are kept to a minimum and that the test set-up is rigorously adhered to. The attenuator used in this test set-up is a series combination of two attenuators. The oscilloscope used needs to a have a high sampling rate and bandwidth. Refer to ISO 7637-2 for details.

Report any damage found to the carrier immediately. Both LD 5550 and LD 5505 modules are in usage. The term “LD Module” is used to refer to either of these modules. All of this information applies to both modules unless specifically refenced by module name. Ensure that the power is turned off on the NSG 5500 mainframe and that the battery input is disconnected. Insert the cassette in the right most slot and push in fully. Screw in the four retaining screws fully. If using the battery switch, ensure this module is present and inserted fully in the rear of the NSG 5500 mainframe. It is vitally important that the unit is connected to a good, protective earth. Turn on the mains input power on the NSG 5500 mainframe. After approximately a two second delay the power LED (red) on the LD module should light. After a further two seconds of initialisation, the unit is ready for operation. The software communications will not start correctly until this initialization time is complete. Now the scope test setup shown in picture 2-9 below 26 should be connected and the output pulses should be quickly checked to ensure that they are of the correct form and shape. When pulses are being generated the relevant green LED (5 or 7, whichever is selected) should flash as pulses are output. When correct operation has been verified, the DUT can be connected to the “OUTPUT” terminals at the front of the unit, and the required tests can be carried out. 2.7.1 Test set-up The following set-up can be used to check the integrity of the output pulses. The scope probe should be in conformance with the specifications outlined in ISO 7637-2.

Report any damage found to the carrier immediately. Ensure that the power is turned off on the NSG 5500 mainframe and that the battery input is disconnected. Insert the cassette in the most left slot and push in fully. Screw in the four retaining screws fully. The battery switch is required, ensure that this module is present and inserted fully in the rear of the NSG 5500 mainframe. It is vitally important that the unit mains power is connected to protective earth. Turn on the mains input power on the NSG 5500 mainframe. After approximately a two second delay the power LED (red) on the MT 5511 generator should light. After a further two-second initialisation period, the unit is ready for operation. The software communications will not start until this initialization time is complete. The scope test set-up shown in picture 2-11 should be connected and the output pulses should be quickly checked to ensure that they are of the correct form and shape. As pulses are generated the “Fire” LED should light briefly. The MT 5511 should be then verified in accordance with Annex C of ISO 7637-2:2011 or similar section of the applicable standard. When correct operation has been verified, the DUT can be connected to the “OUTPUT” terminals at the front of the unit, and the required tests can be carried out. 2.8.1 Test set-up The following set-up may be used to check the integrity of the output pulses. The scope probe should be in conformance with the specifications outlined in ISO 7637-2. CAUTION! it is critical to compensate the probe in advance. Because of the exponential shape of the transients, an uncompensated probe will cause errors on rise time and voltage measurement, and an incorrect pulse shape.

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 184.108.40.206 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. ON 1 2 4 8 16 1 2 3 4 5 6 Picture 2–13: DIP switch array to set the NSG 5500 IEEE address. NOTE! The address is read only at power on. Therefore, after changing the address setting, the NSG 5500 must be powered off and then on to accept the new setting. The hardware is set at the factory to address 1. This is also reflected in the AutoStar setup. NSG 5500 Automotive transient immunity generator 220.127.116.11 IEEE address setting CTR 5501 / CTR 5502 The CTR 5501 address can only be set with the tool supplied on the AutoStar CD using a USB 2.0 Cable. To set the GPIB address, it is first necessary to establish a connection using USB. Please see the section on installing the driver. To choose the GPIB address of the CTR 5501/02, use the Flash Loader Tool found on the AutoStar CD. Once communications is established, click “Set“ to the right of the GPIB address field to bring up this setting dialog. Picture 2–14: Set GPIB address (001 recommended) Select the desired address, then “Ok“ to confirm. The address is immediately sent to the controller interface. 2.9.2 Updating NSG 5500 firmware CAUTION! Updating the firmware should only be done with direct assistance of your local support organization. Incorrectly performed firmware downloads will result in an NSG 5500 that no longer boots and must be sent back for service! 25 26 18.104.22.168 Updating the firmware CTR 5500 The firmware of the CTR 5500 can be updated from within AutoStar. To update the CTR 5500, please see the applicable sections. 22.214.171.124 Updating the firmware CTR 5501 / CTR 5502 The firmware of the CTR 5501 cannot be updated with AutoStar.

The NSG 5500-2 can contain two large and four small transient modules. 34 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. NSG 5500 Automotive transient immunity generator 126.96.36.199 CDN 5500 - Power entry and battery switch This unit is used to bring mains input into the system and to connect the battery input to the system power bus. Bus expansion connector Remote interface Battery terminals (sense) Thermal circuit Mains input breaker with fuses 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. 1 On / off switch 0 Mains input connector 110 - 115 38 Rotate this Insert to change 220 - 240 voltage selection This indicator determines voltage selected Picture 3-5: Power entry module of the NSG 5500 (located in the CDN 5500). 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. A general block diagram of the CDN 5500 and CDN 5501 unit for the NSG 5500 system could be represented as follows. Switch + - Battery + Timer Switch Voltage control control sense (Optional most newer standards) Battery + Picture 3-7: Block diagram of the CDN 5500 battery switch unit. 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. 39 40 188.8.131.52 Control unit The control unit houses the processor board which controls the complete NSG 5500 system. The remote control interfaces are also mounted on this unit. The USB or RS 232 and IEEE 488 interfaces are supplied as standard on all NSG 5500 systems.

IEEE IEEE Interface(s) Picture 3-10: IEEE remote control of the NSG 5500 NOTE! The Windows based application program «AutoStar» allows full remote control and test sequences to be developed within the graphical Windows environment. 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. 220.127.116.11 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. Picture 3-11: HV supply of the NSG 5500.

It can be used to indicate that a DUT failure has occured. Once this signal input is pulled low the present pulse generation pattern will be aborted and testing will end. The AutoStar software can automatically detect the state of the DUT FAIL signal input and will stop the program execution automatically if it detects a low signal. The DUT FAIL input signal is optically isolated. The schematic for this input is as follows. +5 V 1K +5 V 1K Pin 5 Pin 5 Pin 1 GND Picture 3-17: Schematic for the DUT FAIL signal input.

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.

In keeping with the specifications, the following relationships result during calibration measurements: Pulse at generator output: 120 V Pulse at 50 Ω connection: 60 V NSG 5500 Automotive transient immunity generator 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.

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!

NSG 5500 Automotive transient immunity generator 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. Fig. 3.6 - A Typical ARB Test in AutoStar NOTE!
