"Error condi-
tion"
Triggers on one or more errors that are detected in the decoded data,
see "Error conditions" on page 314.
SCPI command:
TRIGger<m>:FLXRay:TYPE on page 722
Indicator bits
Triggers on one or more indicator bits at the beginning of the header segment. Each bit
can be set to 0, 1, or X (don't care).

"Payload pre-
amble"
Indicates a Network Management Vector in the payload segment. The
NMV allows the host processor to send data directly, without processing
by the communication controller.
"Null frame"
Indicates a frame without usable data.
"Sync frame"
Indicates that the frame is used for synchronization of the FlexRay sys-
tem. Only sync nodes can send this frame type.
"Startup frame"
Indicates a startup frame used for startup of the network. Only specific
start nodes can send this frame type.

Frame ID (min/max)
The frame ID contains the number of the slot in which the frame is transmitted. Each
frame ID occurs only once during a FlexRay cycle.

To trigger on a frame ID, you have to define a condition and one or two identifier patterns.
The second identifier pattern is required to specify a range with conditions "In range" and
"Out of range". In binary format, use the following characters: 1; 0; or X (any bit). The use
of X is restricted to the conditions "Equal" and "Not equal". If the identifier is not relevant
for the trigger setup, set it to "Off".
