For example to trigger from an external clock or with a signal from another part of the test circuit The EXT EXT 5 trigger sources use the external trigger signal connected to the EXT TRIG connector Ext uses the signal directly it has a trigger level range of 0 6V to 0 6V The EXT 5 trigger source attenuates the signal by 5X which extends the trigger level range to 3V to 3V This allows the oscilloscope to trigger on a larger signal 2 Trigger Mode The trigger mode determines how the oscilloscope behaves in the absence of a trigger event The oscilloscope provides three trigger modes Auto Normal and Single Auto This sweep mode allows the oscilloscope to acquire waveforms even when it does not detect a trigger condition If no trigger condition occurs while the oscilloscope is waiting for a specific period as determined by the time base setting it will force itself to trigger Normal The Normal mode allows the oscilloscope to acquire a waveform only when it is triggered If no trigger occurs the oscilloscope keeps waiting and the previous waveform if any will remain on the display Single In Single mode after pressing the Run Stop key the oscilloscope waits for trigger While the trigger occurs the oscilloscope acquires one waveform then stop Single In Single mode after pressing the Run Stop key the oscilloscope waits for trigger While the trigger occurs the oscilloscope acquires one waveform then Stop
