10.9 MIL-STD-1553B Trigger and Serial Decode
This section covers triggering and decoding MIL-STD-1553B signals. Please read the
following for more details:
MIL-STD-1553B Signal Configuration , and MIL-STD-
1553B Serial Decode .
Before configuring the signals settings connect the MIL-STD-1553B signal to the
oscilloscope.

Protocol Signals
To set the source and threshold of the MIL-STD-1553B signal use the touchscreen to
select
Protocol Signal :
1. The MIL-STD-1553B menu will be displayed. (Figure 10.46 )
2. Use the touchscreen to select Source and select the source the signal is connected to.
3. Use the touchscreen to select Upper Threshold and input the desired threshold
– The threshold voltage level is for decoding, and it will be regarded as the trigger
voltage level when the trigger type is set to serial.
– The threshold level line only appears when adjusting the threshold level.
4. Use the touchscreen to select Lower Threshold and input the desired threshold
– The threshold voltage level is for decoding, and it will be regarded as the trigger
voltage level when the trigger type is set to serial.
– The threshold level line only appears when adjusting the threshold level.
