ABSTRACT:
The invention relates to an acquisition path for acquiring a voltage pulse, and to a system and a method making use of said path, the path comprises:
a path input for a pulse signal;
a module for determining the polarity and for limiting acquisition of the input signal;
a control module for controlling acquisition and for storing the polarized peak value of the input signal;
a detect-and-hold module for detecting the polarized peak value of the signal being acquired, and for holding it; and
selection means for selecting the rating of the signal being acquired;
according to the invention the selection module for selecting the rating of the signal being acquired comprises a plurality of measurement ranges all of which are connected at their upstream ends to the path input, and all of which are connected at their downstream ends to automatic selection means for automatically selecting the optimum measurement range for the signal being acquired.
