Micropulse Generator

MPG 200S20 - Automotive Micropulse Generator

Micropulses occur on the battery supply system when an inductive load is disconnected from the DC supply. These pulses are of a medium energy content having a rise time in the low microsecond range and a duration of several tenth or hundreds/thousands of microseconds. Their polarity depends on whether the inductive load is of a passive (e.g. a heater) or an active type (e.g. a DC motor).

The MPG 200S20 has a built-in battery switch to interrupt the DC supply voltage as required by the standards. It is designed to generate pulses 1b and 6 as per GOST standard 28751-90 as well as pulse 6 as per ISO 7637-1:1990.

MPG 200S20 - Standalone Micropulse Generator with built-in Battery Switch

The MPG 200S20 includes everything necessary to conduct fully compliant tests. The built-in electronic battery switch enables interruption of the DC supply voltage as required by the standards. The MPG 200S20 is a standalone tester including a 60V/25A DC coupling/decoupling network but still it can be integrated easily into a complete test system.

Operation is both manual and by software via GPIB or RS232. Fail inputs allow to control an ongoing test sequence based on the status of the DUT. A warning lamp control contact and a safety interlock is provided.

Pre-programmed Standard Test routines allow highest user convenience. Still the MPG 200S20 offers the Quick Start test routine where parameters can be changed on-line during the test to evaluate the susceptibility level of an individual DUT.

Easy to operate

iso.control software for control and documentation

Outstanding user convenience, clearly structured windows and operation features and the EM TEST standards library along with the flexibility to generate user specific test sequences very easily are the main features of iso.control software. The software is automatically configured according to the connected EM TEST generators. iso.control software covers international/national standards and most of the manufacturer standards and is continuously updated. Extensive reporting capabilities help the user to create test reports that meet international requirements.

iso.control is supported by Windows 98, Windows 2000, Windows XP, Windows Vista and Windows 7. Remote control is achieved either via USB/RS232 or GPIB. iso.control supports a wide range of GPIB cards of National Instruments.

MPG 200 Micropulse Generator Series

EM TEST offers various Micropulse generators to cover the different test requirements of international/national standards and car manufacturers world-wide.

CA ISO - Load resistors to verify Micropulses and Load Dump pulses

A set of highly-accurate load resistors is unified in a single box for the verification of micropulses and Load Dump pulses under defined loaded condition as specified in ISO 7637-2:2004, Annex D and a wide range of manufacturer specifications.
