MIL-STD 1553 Eye-diagram Mask Testing Application Note Probing the Differential MIL-STD 1553 Bus MIL-STD 1553 eye-diagram mask testing is based on capturing and overlaying all "1" and "0" bits of the differential bus. The differential bus must be probed using a differential active probe. Agilent recommends using the N2791A 25-MHz differential active probe shown in Figure 1. The attenuation setting on the probe should be set to 10:1 (not 100:1). The output of the probe should be terminated into the scope's default 1-M input termination. 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 mask testing can be performed on differential MIL-STD 1553 signals using an Agilent 3000 or 4000 X-Series oscilloscope licensed with the DSOX3AERO/ DSOX4AERO triggering and decode option (MIL-STD 1553 & ARINC 429), along with the DSOX3MASK/DSOX4MASK mask test option. Various MIL-STD 1553 mask files can be downloaded from Agilent's website at no charge. Save the appropriate MIL-STD 1553 mask files to your personal USB memory stick and then insert the memory stick into the scope's front-panel USB port. The following MIL-STD 1553 mask files are available:
