CAN Trigger

Depending on the selected CAN trigger type, different additional parameters are avail-

able.

"Start of Frame"

Triggers on the stop bit of the sync field.

"End of frame"

Triggers after a wakeup frame.

"Frame type"

Triggers on a specified frame type (data, remote, error, or overload).

For data and remote frames, also the identifier format is considered.

"Identifier"

Sets the trigger to a specific identifier or an identifier range. Only the

6-bit identifier without parity bits is considered, not the protected iden-

tifier.

"Identifier + Data"

Sets the trigger to a combination of identifier and data condition. The

instrument triggers at the end of the last byte of the specified data

pattern.

"Error condition"

Identifies various errors in the frame. You can select one or more

error types as the trigger condition.
