MIL-STD-1553/ARINC 429 triggering and serial decode requires the AERO license 
that you can get by purchasing the DSOX3AERO upgrade.
The MIL-STD-1553 triggering and decode solution supports bi-phase 
MIL-STD-1553 signaling by using dual threshold triggering. The solution supports 
the standard 1553 Manchester II encoding, data rate of 1 Mb/s, and word length 
of 20 bits.
Setup for MIL-STD-1553 Signals
MIL-STD-1553 signal setup consists of first connecting the oscilloscope to a serial 
MIL-STD-1553 signal using a differential active probe (the Keysight N2791A is 
recommended), specifying the signal source, and specifying the high and low 
trigger threshold voltage levels.
To set up the oscilloscope to capture MIL-STD-1553 signals:
