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
