MIL-STD-1553 Decode Trace Annotations
Like all trace annotations, MIL-STD-1553 Decode annotations are rectangular shadings used to highlight
messages on decoded waveforms for easy viewing.
Tip: Data packets (or messages) on properly decoded protocol signals can be viewed using Serial Decode Trace
Annotations (on page 18), the Protocol Results Table (on page 19), and/or by Searching for Messages (on
page 21) (Types and Subtypes). Using these tools together provides fast insight to your data. See Serial Decode
Trace Annotations (on page 18) for more information.
Messages shown as annotations, table columns, and search types for most protocols are classified into Frames,
Errors, Unknown, or Grouped Primitives specific to the protocol. Sub Types then further classify each main
message type into more protocol-specific messages.
Decode annotations unique to MIL-STD-1553 include the following (some annotations are not shown in the
screen-shot):

Whether selected or not from the Error Right-Hand Dialog covered in MIL-STD-1553 Trigger Setup Detail (),
errors produced from the Word and Transfer Level Errors checkboxes (Sync, Manchester, Parity, and InvalidSync
Errors) are then displayed on waveforms in a 3-Letter form. An example is the par: annotation on the following
decoded waveform.

par - Parity Word Error

ADD - Add Mismatch Transfer Error

RTI - Response Time Transfer Error

WCO - Word Count Transfer Error

IMG - Inter-Message Gap Transfer Error

Msg - Displays the symbolic information.

CTG - Non-Contiguous Transfer Error
PLEASE NOTE THE FOLLOWING:

Lowercase error codes are for Word errors, while Uppercase error codes are for Transfer errors.

Specifications are subject to change without notice.
