Simultaneous measurement in two bandwidths thanks DualPath - no compromises, no doubt

In Power meters of traditional construction, a signal first passes through an analog processing, the output values ​​are digitized by an A / D converter and then processed. The resulting signal may then either measured over the full range, or treated with anti-aliasing filters, e.g., to serve as the basis for an FFT or other digital filtering. By restriction to an A / D converter, one has to taken certain disadvantages into account. If measured with a filter, in order to avoid aliasing in the FFT, the broadband values ​​are lost. When the filter is disengaged, strictly speaking, the FFT has to be omitted. If the FFT is performed without anti-aliasing filter for measurement over the full bandwidth, the quality of the calculated values ​​is questionable. For example, an aliasing error of 50% would of course be easily detected, a deviation of 0.5% could remain unnoticed. Finally, it can be switched back and forth between measurements with and without filters. The validity of these results is, however, also doubtful, as would be expected of a temporal invariability of the signal, which is hardly ever the case in reality. Moreover, this method is extremely time consuming.

Ultimately, the shown measurement methods are unsatisfactory compromises. For this reason, ZES ZIMMER has radically redesigned the signal conditioning and developed the DualPath architecture. The analog side corresponds to the conventional instruments, the subsequent digital processing, however, was revolutionized. The power analyzers of the LMG600 Series are the first power meters featuring two A / D converters in each of the two independent signal paths for current and voltage channel. A filter for the contact measurement of the broadband signal, and another for the narrowband signal at the output of anti-aliasing filter. By means of parallel processing of the digitized samples, the user has access to both measurements of the same signal without the risk of aliasing. This unique process eliminates all the disadvantages of previous approaches and guarantees accurate results in the shortest time.
