Explanation
Auto Mode
If the trigger condition is met within the 50-ms timeout period, the waveform is updated
on each trigger occurrence. If the trigger condition is not met after the timeout period
elapses, the waveform is automatically updated. If the time axis setting is in the range in
which the display mode is set to roll mode, the display is set to roll mode. However,
triggering operates in normal mode when using simple trigger with the trigger source set
to Time, even if auto mode is specified.
Auto Level Mode
Within the timeout period (approximately 1 s), the waveforms are displayed in the same
fashion as in the auto mode. If a trigger does not occur within the timeout period
(approximately 1 s), the center value of the amplitude of the trigger source is detected,
the trigger level is automatically changed to the center value, and the trigger is generated
to update the displayed waveform. The auto-level mode is valid only if the trigger is a
simple trigger and the trigger source is between CH1 and CH16. For all other cases, the
operation is the same as for auto mode.
If the time axis setting is in the range in which the display mode is set to roll mode, the
display is set to roll mode.
Normal Mode
The display is updated only when the trigger conditions are met. The display is not
updated if the trigger does not occur. Therefore, to check the waveform or ground level
when no trigger is detected, use auto mode.
Single Mode
When the trigger condition is met, the displayed waveforms are updated only once, and
acquisition stops. In the time axis setting range in which the display mode is set to roll
mode, the display is set to roll mode. When a trigger occurs, the specified record length
of data is acquired and the displayed waveform stops.
