    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 437 simualtor is not a toy! It is a professional tool and belongs only in the hands of specialists and appropriately trained personnel. The instrument must not be switched on unless a correctly connected earth or earth cable (pulse current return path) is in place.
  • 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 simulator to a Teseq service centre immediately for repair. Teseq 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 Of Esd Phenomenon

    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 437 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 11: Effects On The Eut

    ESD testing usually shows up all the weak spots in the HF-range of a piece of equipment simultaneously. The uses to which the NSG 437 ESD simulator can be put hence go way beyond those called for in standard-conform applications.

    Both the operating elements and the display window remain in view of the user while work is in progress. NSG 437 offers optimal freedom of movement around the workplace 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 19: Measurement Adapters

    4.2.4 Measurement adapters The measurement adapter type MD 101 as per IEC / EN 61000-4-2 (2001) serves to verify pulse amplitudes and pulse shapes. It is designed for mounting in the side wall of a Faraday cage in which an oscilloscope has been installed. This measurement adapter has the flat impedance curve to well over 1 GHz that is necessary for the purpose.

    Before putting the instrument into operation: Study the manual Take the necessary safety precautions Connect the earth cable correctly (NSG 437 must never be switched on without a solid earth connection being made) Allow the instrument to dry out if any condensation has occurred 5.1 Function test...
  • Page 21 High voltage generation is activated by pushing the trigger button and keeping it depressed. By bringing the test finger close to the earthing point an arc discharge occurs which is acknowledged acoustically and the display shows the preset discharge voltage in a frame.

  • Page 22: Operation

    6 OPERATION This section of the manual provides a guide through the numerous operating possibilities of the NSG 437. 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. Equally, the instrument refuses to accept any invalid entries.

  • Page 23: Operation And Settings

    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. The active high voltage state is indicated on the base station by a blinking red LED. Should a parameter need changing the operator has only to press on the rel- evant field in order to call up the appropriate menu.

  • Page 27: Threshold

    6.3.4 Threshold This function permits to switch the threshold to "normal" or "off". Normal: Arcing is detected and is indicated by the kV symbol on the display blinking provided 20% (or more) of the charge voltage is dissi- pated. Off: This means in contact-discharge mode, the arcing detection is disregarded and the counter counts up / down as per settings in the repetition or counter menu respectively.
