ABSTRACT:
The present invention provides, a pulse generator, which is configured so as to generate pulses with a predetermined pulse width, comprises: multiple pulsers each of which is configured so as to adjust the pulse width of input pulses, and so as to output pulses with a predetermined pulse width thus adjusted, and which are connected in series; multiple signal acquisition units which are provided corresponding to the multiple pulsers, and each of which allows the pulses output from a corresponding one of the pulsers to be acquired at a position immediately after the output terminal of the corresponding pulser; a selection unit which allows the pulses acquired by one of the multiple signal acquisition units to be selected; a feedback path for inputting the pulses thus selected by the selection unit to the first pulser of the multiple pulsers; and a measurement unit for measuring the pulse width of the pulses thus selected by the selection unit based upon the loop cycle time of the pulse selected by the selection unit passing through the feedback path.
