Advance Oscilloscope Triggering

In this paper, we present an advanced triggering method for digital oscilloscopes for measurements involving complex waveforms that are challenging even today. Based on the associative-memory technique and on utilizing a new weighted-hamming-distance parameter, this technique is capable of providing stable oscilloscope triggering, even for complex waveforms where the commonly used voltage level triggering method fails to perform adequately. The proposed technique has been verified by exhaustive software simulations using Matlab and Xilinx foundation series softwares. Furthermore, the technique has been implemented and validated on a XCV300EPQ240 field-programmable gate array device and has given successful initial results using several different kinds of test waveforms
