Testing signal generator for sequence of event

The utility model provides a testing signal generator for sequence of event (SOE), which is additionally provided with a GPS clock signal receiver and a timer. The GPS clock signal receiver is used for being connected with a device providing GPS clock signals, acquiring the GPS clock signals from the device and controlling the timer to synchronize with a GPS clock. After setting the test start time, a user starts the timer to time the test start time; and when the time of the timer is arrived, triggering signals of each channel in a triggering signal output module are generated. The SOE testing signal generator ensures the absolute time precision of happening events, can conveniently detect the clock synchronization performance of a detected system, can measure in different triggering sequence without changing the connecting mode of cables when the detecting objects are a plurality of SOE recoding modules, and has low requirement on the cables.
