The fully compliant harmonics and flicker analyzer

The EM Test DPA 503N is a fully compliant analyzer for harmonics and flicker as per the latest IEC/EN 61000-3-2, IEC/EN 61000-3-3 and JIS C 61000-3-2 as well as IEC/EN 61000-3-11 and IEC/EN 61000-3-12:2011 requirements. The DPA 503N has six independent input channels; three for voltage and three for current. It follows the design specifications as per IEC/EN 61000-4-7:2009 (for Class A instruments) for harmonics analyzers and IEC/EN 61000-4-15:2010 for flicker meters.

Based on a real-time kernel and equipped with its own harddisk it allows to record the measuring data continuously without any gaps or overlapping. The rectangular measurement window is synchronised to each group of 10 or 12 cycles of the mains supply frequency (50Hz or 60Hz) by means of a digital PLL (Phase Lock Loop). A wide-range current input (up to 140A) avoids loss of measured data due to range switching that would occur when using different shunt resistors.

The classification of the measurement can be selected at any time, before or after the measurement has been performed. During all measurements the AC supply voltage is measured simultaneously with the current.

net.control – Editing, documenting and managing your waveforms and standard tests

Software for NetWaveZoom


net.control is the tool to easily and conveniently control the NetWave. By means of net.control the user can program any kind of waveform either composed from segments or points and download into the NetWave. Enhanced graphic tools are at hand to adjust the waveform according to individual requirements.

net.control provides a library of an extensive compilation of predefined segments as well as a large number of standard test routines as per EMC and avionics standards. net.control is also handling any waveform recorded by other method (e.g. captured by an oscilloscope) or imported as Excel or CSV files. All waveforms can be downloaded into the NetWave.

net.control offers an enhanced reporting tool to generate test/measuring reports and can be used under Windows 7, Windows 8 (64 Bit) and Windows 10.
