Sequence signal generator and sequence signal generation method

A sequence signal generator, comprising:

• a communication module,
• a waveform output module,
• a waveform data storage module, and
• a time delay module, wherein
• the time delay module comprises at least one preliminary delay unit and at least one secondary delay unit, and a delay time of the preliminary delay unit is greater than a delay time of the secondary delay unit, and the delay time of the preliminary delay unit and the delay time of the secondary delay unit are both less than a system clock cycle;
• the communication module is configured to receive an instruction sent by a host computer and transmit the instruction to the waveform output module;
• the waveform output module is configured to, in a case of determining the instruction as a waveform output instruction, read waveform data from the waveform data storage module in response to the instruction, wherein the wave data comprises original square wave sequence data and target square wave sequence data;
• generate an original square wave sequence signal based on the original square wave sequence data;
• and transmit the original square wave sequence signal and the target square wave sequence data to the time delay module, wherein the target square wave sequence data comprises a preliminary delay parameter and a secondary delay parameter;
• and
• the time delay module is configured to perform a preliminary delay processing on the original square wave sequence signal by the at least one preliminary delay unit according to the preliminary delay parameter to acquire an intermediate square wave sequence signal, perform a secondary delay processing on the intermediate square wave sequence signal by the at least one secondary delay unit according to the secondary delay parameter to acquire a target square wave sequence signal, and output the target square wave sequence signal.
