TRIG DELAY The trigger delay field allows the trigger point to be positioned
anywhere in the acquisition window. A negative value will
provide pre-trigger information on data leading up to the trigger
event. The pre-trigger delay cannot exceed the length of the
acquisition buffer. See paragraph 4.6.3.3 for details. A positive
trigger delay positions the data window after the trigger event.
Positive trigger delays can exceed the length of the acquisition
buffer in which case the trigger event itself will not be in the
buffer any more. The maximum value of the trigger delay is
1000 ms. The default trigger delay value is 0.0 ms, which puts
the trigger event at the beginning of the acquisition window.
START The START field is used to start a new acquisition run. To start
an acquisition, place the cursor on the START field and press
the ENTER key. Once the ENTER key is pressed, the display
toggles to the data display mode selected in the VIEW field as
soon as the selected trigger event occurs. To return to the
HARMONICS/TRACE ANALYSIS menu, press the ENTER key
while in the data display mode.
To change display modes without triggering a new acquisition,
make the desired changes in the menu and move the cursor to
the VIEW field. Once on the VIEW field, press the ENTER key.
This will not trigger a new acquisition, which means the original
data is retained.
