Acquisition Window Trigger Points
Pretrigger
Seven-eighths of the waveform acquisition window is prior to
the trigger (other trigger points are selectable via the MENU).
'Performance requirement not checked in manual.
4Holdoff in STORE mode is a function of microprocessor activity and the pretrigger acquisition. The VAR HOLDOFF control main-
tains some control over the STORE
holdoff
by
preventing a new trigger from being accepted by the storage circuitry until the next
(or current, if one is in progress) NON-STORE
holdoff has completed.
