Claim 15:
16. The oscilloscope according to claim 10, wherein the characteristic parameter data comprises envelope variation information, and calculating the envelope variation information of the to-be-triggered signal comprises:
determining whether the to-be-triggered signal is a modulated signal, and in a case where the to-be-triggered signal is the modulated signal, generating a pulse signal corresponding to a modulated wave;
detecting a pulse width of the modulated wave and a period of the modulated wave; and
determining whether a difference between a maximum value of the pulse width of the modulated wave and a minimum value of the pulse width of the modulated wave during a fourth time is greater than a preset second pulse width variation threshold, and determining whether a difference between a maximum value of a period of the modulated wave and a minimum value of the period of the modulated wave during a fifth time is greater than a preset period variation threshold.
