    1 EXPLANATION OF THE SYMBOLS USED IN THIS MANUAL Please take note of the following explanations of the symbols used in order to achieve the optimum benefi t from this manual and to ensure safety during operation of the equipment. The following symbol draws your attention to a circumstance where non- observation of the warning could lead to inconvenience or impairment in the performance.

  • Page 6: Safety

    The NSG 438 simulator is not a toy! It is a professional tool and belongs only in the hands of specialists and appropriately trained personnel. When powered by its own batteries the generator can be active even without any power cable being connected.
  • Page 7 The instrument’s housing and the cable have both an insulating and a screen- ing function, which can only be assured while the housing is intact. Return a damaged generator to a Teseq service centre immediately for repair. Teseq AG Luterbach, Switzerland and the associated sales organization accept no responsibility for personal or material damage nor for any consequential damage that results from irresponsible operation of this instrument.

  • Page 8: Introduction

    The high equalizing current that fl ows, and the associated large electromagnetic fi eld that hence results, can cause electronic devices (computers, terminals, process controllers, vehicle electronics, solid state devices, credit or memory cards, etc.) to malfunction or even be destroyed. NSG 438 /438A ESD simulator...

  • Page 9: Simulation

    3.2 Simulation A systematic investigation of electronic equipment and installations to deter- mine their electromagnetic compatibility (EMC) is, today, a necessity if one is not prepared to suffer the economic disadvantages that could otherwise ensue. As a logical consequence, appropriate testing is now a legal requirement for the sale of electronic products within the EU.
  • Page 10 The ESD simulator NSG 438 fulfils the requirements of numerous applications in an ideal manner, thus: Ergonomic shape: For non-tiring use. Operation: Operating elements and display always in view of the user. Constant check on the test values. Battery-powered: Independence from a mains power feed.

  • Page 11: Effects On The Eut

    ESD (electrostatic discharge) testing usually shows up all the weak spots in the HF-range of a piece of equipment simultaneously. The uses to which the NSG 438 ESD simulator can be put hence go way beyond those called for in standard-conform applications.

  • Page 12: The Nsg 438 System

    Both the operating elements and the display window remain in view of the user while work is in progress. The NSG 438 offers optimal freedom of movement around the work-place and is an ideal test instrument not just for the development engineer but also for quality control purposes, system tests and for investigations in the field.

  • Page 13: The Simulator

    4.1 The simulator The NSG 438 simulator is modularly constructed from a number of discrete function units. 4.1.1 Function modules The base station contains the battery supply, the high voltage generator and regulator as well as several safety features.

    This port is intented to allow the user to connect external signals in order to remote control the NSG 438 generator, as well as to connect external acces- sories like the charge removing device INA 4430. See tables and graphs below for detailed signal description and drive circuitry information.

  • Page 22: Interlock

    2. Internal emergency off button opens the interlock. Outputs 1. Operating mode: the NSG 438 can generate no high voltage as long as the interlock is not closed. High voltage generation is prevented if the interlock is opened during a test procedure.
  • Page 23 An arbitrary number of instruments or accessories can be incorporated in this safety concept. The high voltage supply can only be activated if the safety requirements in all the associated devices are fulfilled (emergency off buttons released, safety contacts closed). The control of the warning lamps must make use of the interlock feature.

  • Page 28: Operation

    6 OPERATION This section of the manual provides a guide through the numerous operating possibilities of the NSG 438. The operation, hierarchically arranged, is therefore easy to remember. The display shows unmistakable information about the parameters that have been set and the operating status of the simulator.
  • Page 29 Press the interlock reset button. The red interlock LED will extinguish and the red high voltage LED blinks while the pistol runs its self-test and calibration routine. The instrument is ready for use immediately after self-test and calibration pro- cedures have been completed. High voltage generation is activated by pressing and holding the trigger button.

  • Page 31: Display Mode

    6.3.1 Display mode When adjusting some parameters a keyboard and up / down buttons can be selected. Numerical values (voltage, preset counter, random repetition times) can be entered just the same as with a pocket calculator. Selection functions (such as language, type of discharge, program number, etc.) are handled by up / down buttons to scroll through the settings.
