Using XDEV Customization to convert to digital waveform LeCroy Application Brief No. LAB 766 Decoding NRZ Data Using XDEV Customization to convert to digital waveform Non-Return to Zero (NRZ) sig- nals use two voltage levels (high and low) to represent logic one and logic zero values. Traditional oscilloscopes can capture and view these wave- forms but do not have the capa- bility to decode waveforms into their digital equivalents. Oscil- loscopes with XDEV custom functionality can now decode these waveforms. In Figure 1, a block of NRZ data is acquired as Function F1 and the parameter TIE@lv (Time Interval Error) is applied as parameter P1. The Virtual Clock capability of TIE reports Figure 1 The Virtual Clock tab of the TIE@lv parameter is used t……
