Trigger mode (Trigger Mode)
Auto
If the trigger conditions are met within a 50-ms timeout period, the instrument updates the displayed
waveforms on each trigger occurrence. If not, the instrument automatically updates the displayed
waveforms. If simple trigger is in use and the trigger source is set to Time, the instrument operates
in Normal mode even when Auto mode is specified. If the time axis is set to a value that would
cause the display to switch to roll mode, roll mode display will be enabled.
Normal
The instrument updates the waveform display only when the trigger conditions are met. If no
triggers occur, the display is not updated. If you want to view waveforms that the instrument cannot
trigger on, or if you want to check the ground level, use Auto mode.
Single
When the trigger conditions are met, the instrument updates the displayed waveform once and
stops signal acquisition. If the time axis is set to a value that would cause the display to switch to
roll mode, roll mode display will be enabled. When the instrument triggers, it begins recording data.
When data has been acquired up to the amount specified by the set record length, the waveform
display stops.
On Start
Regardless of the trigger settings, when you press the START key, the instrument updates the
displayed waveforms once and stops signal acquisition. If the time axis is set to a value that would
cause the display to switch to roll mode, roll mode display will be enabled. When data has been
acquired up to the amount specified by the set record length, the waveform display stops.
