PROBLEM TO BE SOLVED: To provide triggering on detecting specific analog anomalies and/or digital data contained in a specific identification area of a serial data stream. SOLUTION: A start word recognizer 16 detects a start pattern in the serial data stream to generate an enable signal. Then a stop word recognizer 18 detects a stop pattern in the serial data stream to generate a disable signal. An arm circuit 24 generates an identification signal which indicates a period between the enable signal and the disable signal. A trigger circuit 30 generates a trigger signal if detecting an analog anomaly and/or specific digital data generated during a period of the identification signal. COPYRIGHT: (C)2007,JPO&INPIT
