Status words are returned by remote terminals in response to
a valid message from the controller to acknowledge receipt of
a message or to convey the remote terminal status. The first
5 bits of the 16-bit information field are the terminal address.
The remaining bits represent specific status information,
including Message Error, Instrumentation Bit, Service Request,
Broadcast Command Received, Busy, Subsystem Flag,
Dynamic Bus Acceptance, and Terminal Flag.
Working With MIL-STD-1553
MIL-STD-1553 Serial Triggering and Analysis options are
available on several Tektronix oscilloscope families (see
Appendix A).
You can easily connect to a 1553 bus using passive probes
on any of the analog channels and set up the bus parameters
by pressing the front panel bus button and the on-screen
menu. To isolate specific events on the MIL-STD-1553 bus,
the oscilloscope can trigger on Sync, Word Type, Data Word
value, and Parity Error.
With the available serial triggering and analysis options, you
can easily view MIL-STD-1553 serial signals, analyze them,
and correlate them to other events in your design.
