Normal trigger mode
Normal trigger mode causes the instrument to wait for a valid trigger event before displaying waveform data. Normal trigger mode
is most useful during single-shot acquisitions.
Auto trigger mode
Auto trigger mode causes the instrument to trigger if a valid trigger event does not occur within a set amount of time.
Auto trigger mode is useful when probing DC signal levels such as power supplies or logic levels that are stuck high or low. It is
also useful when looking for activities on signal nodes such as oscillations when you first set up the instrument. The length of
time it waits for a trigger event depends on the time base setting.
Force Trigger
Click this button to force the instrument to trigger and complete the current acquisition, regardless of whether any other trigger
event occurs.
NOTE. This command has no effect if the acquisition system is not running.
Push the front-panel Level knob. This control is also available in some trigger setup windows.
To use
Click this button to have the instrument automatically search for and set the trigger level to a value halfway between the peaks of
the trigger source signal.
NOTE. Some trigger types support multiple trigger levels, whereas other trigger types are unsupported, and the front-panel
control is inoperative. This control also works differently for certain Comm triggers.
