ARINC 429 Eye-diagram and Pulse-shape
Mask Testing
Application Note
Introduction
Eye-diagram mask testing is used in a broad 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 affects, 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 a Keysight
Technologies, Inc. 3000, 4000 or 6000 X-Series oscilloscope
licensed with the DSOX3AERO/DSOX4AERO/DSOX6AERO
triggering and decode option (MIL-STD 1553 & ARINC 429), along
with the DSOX3MASK/DSOX4MASK/DSOX6MASK mask test
option. Various ARINC 429 mask files can be downloaded from
Keysight's website at no charge. Save the appropriate ARINC 429
mask files (based on baud rate) to your personal USB memory
stick and then insert the memory stick into the scope's front-
panel USB port. The following ARINC 429 mask files are available:
