On conventional power analyzers, a signal first undergoes analog conditioning, followed by optional anti-aliasing filters, to then be fed into an A/D converter. The resulting signal can afterwards be used for the calculation of cycle-based RMS values. Alternatively it can serve as the base for an FFT or further digital filtering. Due to the limitation to a single A/D converter, there are inherently some downsides to be factored in with conventional devices. If measurements are carried out with filters active, in order to avoid aliasing with FFTs, then the wide-band values are lost. With the...

Precise measurements thanks to optimal alignment Accurate power measurement requires a poor utilization of measuring ranges, that 0 < λ <1. Even standby measurements and highly fine-tuned alignment of current and even a small offset can produce errors in gas discharge lamps, which are still used in voltage channels. This is where the LMG600 the magnitude of single-digit percentages. video projectors, pose no challenge for the series is setting a new global standard with At high frequencies and thus very short pe- timing differences of <3 ns.

Current sensors LMG Test Suite The tests performed by LMG Test Suite are in accordance with the currently valid edition of EN 61000-3-2/-12 or EN 61000-3/-11, and measurements according to ECE R-10.4 Annex 11 (electromagnetic compatibility of vehicles), for example, are also possible. The LMG Remote PC software allows to easily control the LMG610 remotely from a Windows PC. Since this software mimicks the measuring device itself down to the last detail, the LMG610 can be operated as usual, even from the PC - no rethinking required, no familiarization time. © 2016 - ZES ZIMMER Electronic...
