With the active/passive switchable monitoring device MD 4070, Teseq is presenting an up to now unique wide dynamic range. With the generous frequency range from 10 kHz to 600 MHz, it is the ideal accessory of the compact testing system NSG 4070 and other systems. The requirements of IEC/EN 61000-4-6 and the BCI tests have been incorporated in the development of the monitoring device. The MD 4070 can also be used for the EUT monitoring. The active/passive changeover can be made manually and via remote control.
When using the EM-clamp or current injection probe, IEC/EN 61000-4-6 tests require the monitoring and if necessary limitation of the stress level if the requirements for asymmetrical impedance cannot be fulfilled. For these reasons, the test design has a current probe in the test item path. The resulting current and its maximum value can be determined. In the case of unfavourable impedance of the test item during the test, the interference current is limited to a maximum value.
For automotive BCI tests, e.g. according to ISO 11452-4, the use of current probe for measurement of the interference factor for the logging or as part of a closed-loop setup is defined.
The monitoring device MD 4070 completes the product range of Teseq for conducted RF interference in the commercial, automotive and military areas.
