Eye-diagram, pulse-shape mask testing performed on ARINC 429

Eye-diagram mask testing is employed in a wide range of today's serial bus applications. An eye-diagram is basically an overlay of all bits captured by the scope to show when bits are valid and not valid. This provides a composite picture of the overall quality of a system's physical layer characteristics, which includes amplitude variations possibly due to transmission line effects, reflections, system noise, over-shoot, ringing, signal edge timing, and jitter.

Eye-diagram and pulse-shape pass/fail mask testing can be performed on differential ARINC 429 signals using an Agilent 3000 X-Series oscilloscope licensed with the DSOX3AERO triggering and decode option (MIL-STD 1553 & ARINC 429), along with the DSOX3MASK mask test option. Various ARINC 429 mask files can be downloaded from Agilent's website at no charge.
