Functions
Trigger Hold-off
≡
Page 6-5.
≡
The trigger hold-off function temporarily stops detection of the next trigger once a trigger has
been activated. For example, when observing a pulse train signal, such as a PCM code, display
of the waveform can be synchronized with repetitive cycles; or when using the history memory
function, you may want to change the repetitive period, as shown below.

Trigger signal restricted by hold-off time "t" (when "Rise" is selected as the trigger slope)
Trigger Position/Trigger Delay
≡
Page 6-6 to 6-8.
≡
Specify which part of the acquired waveform in the acquisition memory to display on the screen
by setting the trigger position. Trigger position is equal to the trigger point when the trigger
delay is set to 0 s.
By using the trigger delay function, the waveform whose acquisition starting point is delayed
from the trigger point by the trigger delay time can be displayed.

Changing the T/div setting, the time axis setting is rescaled with respect to the trigger position.
The time measurement of cursor measurements and automatic measurement of waveform
parameters is based on the trigger position (0 s).
