Claims

[Scope of utility model registration request]

A pulse width measurement circuit that measures the pulse width of a signal under test, first and second registers that store two specified types of pulse width values, and determination conditions that are set in advance and output from the pulse width measurement circuit. a determination circuit that compares a pulse width value with a setting value outputted from the first register and the second register and outputs an establishment signal when the determination condition is met; and a determination circuit that outputs an establishment signal output from the determination circuit. 1. A trigger signal generation device comprising: a single pulse generation circuit that receives an input and outputs a trigger signal.
