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 435 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 simulator can be active even without any power cable being connected.

  • Page 8: Introduction

    The high equalizing current that flows, and the associated large electromagnetic field 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 435 ESD simulator...

  • Page 9: Simulation

    2.2 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 EC.
  • Page 10 The ESD simulator NSG 435 fulfils the requirements of various applications in an ideal manner: Ergonomic shape For nontiring 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

    MOS or other components 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 435 simulator can be put hence go way beyond those called for in standard-conform applications.

  • Page 12: Nsg 435

    Thanks to its battery pack, the NSG 435 offers optimal freedom of movement around the workplace and is an ideal test instrument not just for the deve- lopment engineer but also for quality control purposes, system tests and for investigations in the field.

    The battery charge state is continuously monitored. A tendency towards low voltage is shown on the display. The instrument’s functions are inhibited once the battery voltage is insufficient to guarantee the pulse parameters. NSG 435 ESD simulator...

  • Page 15: Operating Elements

    Apart from the trigger button itself (pulse triggering) all the operating elements are on the surface of the instrument that faces the operator. The NSG 435 is switched on/off with the main switch. The significance of the elements in the display field can be seen in the following picture.

    It is not per- missible to operate the NSG 435 with a power supply unit from another system. The power supply unit can be used on all common AC mains supplies without...

  • Page 20: Discharge Networks

    The protective earth connection does not replace the earth cable for the opera- tion of the NSG 435. To ensure safe and valid test operation the earth cable must be correctly connected as the pulse return path in every case.

  • Page 21: Remote Triggering

    The normal remote trigger unit consists of a «triggerbox» and 5 m (197 “) of optical cable. The remote trigger works in parallel with the «trigger-button» on the NSG 435. Pulse triggering, or the on/off switching in the case of repetitive discharges, can be effected by a push-button or an electrical signal applied to the triggerbox.

  • Page 24 By bringing the test finger close to the earthing point an discharge occurs which is acknowledged acoustically and the display shows the effective discharge voltage in a frame. (This applies under the following conditions: air-discharge, single-pulse, preselect counter off). The instrument is now ready to use. NSG 435 ESD simulator...

  • Page 25: Operation

    5 OPERATION 5.1 General This section provides a guide through the numerous setting possibilities of the NSG 435. The operation, which is strictly logical and hierarchically arranged, is easy to remember. The display shows unmistakable information about the parameters that have been set and the operating status of the simulator.
  • Page 26 In the case of a contact-discharge this measurement is not carried out since only a discharge current can occur. The instrument switches itself off automatically after a period of 30 minutes of non-use although the parameters that have been set will remain stored in memory. NSG 435 ESD simulator...

  • Page 27: Battery Monitor

    5.3 Battery monitor The battery charge state is monitored continuously. An insufficiently charged or empty battery is indicated on the display. «LOW BAT» blinks: Change or charge the battery soon. The in- struments functions and the pulse data are still assured. «LOW BAT» steady: Battery empty.

  • Page 28: Air/Contact-Discharge

    When working with fixed voltage levels, the relevant value is automatically loaded upon toggling between the air/contact-discharge mode. The corresponding test finger must, of course, be attached to suit the particular discharge mode: Air-discharge = rounded test finger Contact-discharge = pointed test finger NSG 435 ESD simulator...

    Press F5 to return to the starting menu level. (This return will also be made automatically after about 10 s). 5.6 Polarity F3 toggles between positive and negative polarity. The sign shown in the display alters correspondingly. NSG 435 ESD simulator...

  • Page 31: Repetition Frequency

    5.7 Repetition frequency Use F4 to scroll from SINGLE (single discharges) through all the possible frequen- cies for repetitive discharges: 0.5/1/5/10/20/25 Hz for air-discharge 0.5/1/5/10 Hz for contact-discharge In the SINGLE mode a discharge is released each time the trigger button is pressed.

  • Page 32: Preselect Counter

    A specified number of discharges (0...9999) can be pre-programmed with this function. These can then be triggered single by hand or automatically. F5 first resets the counter then, when pressed a second time, branches into the preselect counter menu. NSG 435 ESD simulator...
  • Page 33 F3 switches the preselect counter operation on and off (PRESELECT ON/OFF). Use F1 and F2 to raise or lower the preset value. Keeping either button pressed causes the change to occur with increasing rapidity.

  • Page 34: Automatic Polarity Switching

    5.10 Automatic polarity switching The IEC standards call for equal quantities of positive and then negative dis- charges to be applied to a test point. The NSG 435 can execute this function automatically. The automatic polarity switch operates in conjunction with the preselect counter.
  • Page 35 F5 branches into the preselect counter menu. F4 switches the function «Automatic polarity change» on and off (Precondition: PRESELECT ON). The active state is shown by the polarity sign in front of the voltage alternating on the display.
  • Page 36 This automatic function works in both the single pulse mode as well as with repetitive discharges. Reinitialize the operation in single pulse mode after each cycle. Reset the counter and select the counter menu again (press F5 three times). NSG 435 ESD simulator...

  • Page 37: Continuous Operation

    5.11 Continuous operation A continuous operating mode can be selected for repetitive discharges. Pressing the trigger button starts the continuous operation; pressing it a second time stops the operation. Continuous operation should only be utilized in cases of real necessity since every ESD radiates electromagnetic disturbance the effect of which on the environment must be taken into consideration.
  • Page 38 Use F5 to return to the original menu level. Switching off continuous operation: By F5 branch into the preselect counter menu. Press F1 or F2. The counter shows 0000 or 9999 respectively. Continuous operation is switched off. NSG 435 ESD simulator...
