Trigger is introduced   Trigger: And in order to synchronize the scanning signal and measured signal, can set some conditions, the measured signal is   constantly compared with those conditions, only when the measured signal to satisfy the conditions to start scanning, so as   to make the scanning frequency is the same as the measured signal or exist integer times, which is synchronous Is called a   trigger, the technology that we call the trigger condition.   Trigger condition: used as the trigger condition in the form of many, the most commonly used is the most basic edge trigger,   the change of the measured signal (i.e., signal rising or falling edge) compared with a certain level, when the signal changes in   some selected way to achieve the electricity at ordinary times, generate a trigger signal, start a scan trigger level can be   selected in the 0 v, when the measured signal from low to high across the electricity at ordinary times, have a scan, thus   obtained and measured signal synchronous scanning signal .   trigger mode: Automatic refers to whether meet the trigger condition, real-time refresh waveform, the waveform oscilloscope   screen usually appear to be normal shake refers to satisfy the trigger condition to trigger, stationary wave, the single refers to   capture only meet the waveform of the trigger condition, for the first time will stop after capture.       Function of ignition.   (1) Ignition is introduced.   1) Type of ignition system   The traditional ignition system with a distributor has long been used in cars and has been gradually replaced by a direct   ignition system (DIS).
