There are three types of triggers: internal, line, and external. The internal trigger, activated by the input channel, is the most common and used in previous examples. The line trigger uses the electrical signal (220V, 50Hz) and is used to synchronize noise associated with the electrical network. When selecting this mode, the noise signal is synchronized and appears static on the screen, with a frequency of 50Hz estimated at twenty milliseconds per period. External triggering is used to synchronize input signals with a related third signal. For example, to display aperiodic digital data frames, a periodic signal, such as pulses, is required to serve as a synchronized reference. By selecting the pulse signal from channel two as the external trigger source and adjusting the time base and attenuators, it is possible to display and synchronize part of the digital data frame on the oscilloscope screen. This facilitates taking accurate measurements of the signals in question.
